3 Important information about voltage areas

3.1 Voltage areas for Inline Modular IO and Inline Block IO

Inline Block IO modules are available for the SELV area

Inline Modular IO terminals are available for the SELV and low voltage areas. The terminals are divided into three product groups according to their use in a specific voltage area and their function.

Table 3-1 Voltage areas and corresponding terminal designations for Inline

Voltage area Voltage used for Inline Product group
SELV 24 V DC Low-level signal terminals;		Inline Block IO modules
Low voltage 120 V AC Low voltage terminals; AC		terminals

Observe the safety notes in the following sections when working outside the SELV area.

3.2 Correct usage

Inline Block IO modules and Inline Modular IO terminals should only be used according to the instructions in the terminal-specific data sheets and this user manual. Phoenix Contact accepts no liability if the device is used for anything other than its designated use.

When used in the SELV area:

NOTE: Disregarding this warning may result in malfunction

Do not replace terminals while the power is connected.

Before removing or mounting a terminal, disconnect power to the entire station.

Make sure the entire station is reassembled before switching the power back on.

When used in the low voltage area:

WARNING: Dangerous contact voltage

Do not replace terminals while the power is connected.

Before removing or mounting a terminal, disconnect power to the entire station.

Make sure the entire station is reassembled before switching the power back on.

WARNING: Dangerous contact voltage

Please note that there are dangerous contact voltages when switching circuits that do meet SELV requirements.

When working on the terminals and wiring, always switch off the supply voltage and ensure it cannot be switched on again.

3.3 Notes for Inline Modular IO

3.3.1 Safety notes for use in the low voltage area

Only qualified personnel (qualified electricians or persons instructed in electrical engineering) may work on Inline terminals outside the SELV area.

The instructions given in the terminal-specific data sheets must be followed during installation and startup.

An electrician is a person who, because of their education, experience, and instruction, and their knowledge of relevant standards, can assess any required operations and recognize any possible dangers. (Definitions according to DIN VDE 1000-10:1995).

A person instructed in electrical engineering is someone who has been instructed by an electrician in their required tasks and the possible dangers caused by incorrect handling and, if necessary, has also been informed of the necessary safety equipment and safety measures. (Definitions according to DIN VDE 1000-10:1995).

3.3.2 Safety notes for electrical equipment used in industrial plants with a 400 V AC voltage

WARNING: Dangerous contact voltage

The electrical power-level terminals for the 400 V AC area and connected machines refer to equipment used in industrial plants. During operation, this equipment has dangerous, live, moving or rotating parts. These can therefore cause considerable damage to health or equipment, e.g., due to the unauthorized removal of protective covers or inadequate maintenance.

• Only qualified personnel may work on the power-level terminals or system (for the definition, see Section 3.3.1 on page 16).
• When working on the power-level terminals and the system, you must always keep the operating instructions and other items of product documentation to hand and observe the information therein.
• It is prohibited for unqualified personnel to work on the power-level terminals, on the machine or in their vicinity.

The instructions given in the terminal-specific data sheets must be followed during installation and startup.

The notes on the procedures and the circuit details presented in the terminal-specific data sheets should be understood in a general sense and the relevant application should be tested to see if they apply.

Phoenix Contact cannot guarantee the suitability of the procedures or the circuit suggestions described for the relevant application.

3.3.3 Installation instructions and notes for low voltage terminals

WARNING: Dangerous contact voltage

Please note that there are dangerous contact voltages when switching circuits that do meet SELV requirements.

Connecting and disconnecting the terminals for the 120 V AC and 230 V AC voltage areas is only permitted if the power supply is disconnected.

When working on the terminals and wiring, always switch off the supply voltage and ensure it cannot be switched on again.

WARNING: Dangerous contact voltage in the event of ground faults

(e.g., because the FI circuit breaker has not tripped or the star point connection is "free") Inline terminals for the 120 V AC and 230 V AC voltage areas should only be operated in grounded AC voltage networks (AC networks).

3.3.3.1 Structure of a 120 V AC/230 V AC area

A 120 V AC/230 V AC area must have a power terminal at one end and an end terminal at the other.

I/O terminals for these voltage areas can be used between these terminals. The number of terminals is limited by the system limits of the bus system and the Inline system (see Section 11, "Inline Modular IO: Technical data and ordering data").

Figure 3-1 Typical structure of an Inline station with different voltage areas

1 Bus coupler

2 Power terminal for the 120 V AC or 230 V AC area

3 Various I/O terminals for the 120 V AC or 230 V AC area

4 End terminal for the 120 V AC or 230 V AC area

5 Power terminal for the 24 V DC area

6 Various I/O terminals for the 24 V DC area

3.3.3.2 Fuse protection for a 120 V AC/230 V AC area

Each 120 V AC/230 V AC area must be protected by its own external fuse. Select the rating of the fuse according to the strength of the cable. The maximum fuse value is 8 A. For additional restrictions, please refer to the data sheets for the power terminals.

3.3.3.3 Connecting the power supply and I/O in the 120 V AC/230 V AC area

WARNING: Dangerous contact voltage

The supply voltage must only be provided at the appropriate power terminal.

If you provided voltage to several places in an incomplete Inline station, there would be a danger of touching live parts.

The connecting cables of all actuators and sensors must only be connected to the Inline terminals for the relevant voltage area. The use of external bus bars for group potentials is not permitted.

3.3.3.4 Interrupting PE jumpering in the 120 V AC/230 V AC area

The PE jumper begins at the power terminal of the 120 V AC/230 V AC area and, in a complete AC voltage area, ends at the end terminal.

If a terminal is removed from this area, the PE jumper is interrupted.

If the installation instructions have been followed, all subsequent terminals will be disconnected.

3.3.4 Electronics base and connectors for the different voltage areas

Power-level terminals are located in a power housing.

Low-level signal terminals and low voltage terminals are located in the same type of housing, which is referred to as low-level signal housing. An external feature that distinguishes the base and the corresponding connectors of low voltage terminals from the base and connectors of low-level signal terminals is their color:

Table 3-2 Base and connector colors for the different voltage areas

Area	Terminal	Connector	Other differences
Low-level signal (24 V DC)	Green Green or black		Light color for function identification (e.g., light blue)
Low voltage (120 V AC/ 230 V AC)	Gray Gray Dark color for function identification (e.g., dark blue) with white lightning bolt

3.3.5 Safety mechanisms to prevent incorrect connection of terminals for different voltage areas

3.3.5.1 Protection against the insertion of 24 V DC terminals and power-level terminals in the 120 V AC/230 V AC area

Low-level signal terminals and power-level terminals cannot be snapped-on within a low voltage area because there is no keyway on the right-hand side of the low voltage terminals (120 V AC/230 V AC).

WARNING: Dangerous contact voltage

The power terminals for the 24 V DC area can be inserted in a 120 V AC/230 V AC area. The minimum isolating distance in this case is the distance between two adjacent connectors. This isolating distance is not permitted. Therefore, only use end terminals that are designed for terminating the 120 V AC/230 V AC area.

3.3.5.2 Protection against the connection of 24 V connectors to 120 V AC/230 V AC terminals

The two terminal points for the low voltage I/O terminals are closed using filler plugs. The connectors for low-level signal terminals therefore do not fit on the low voltage terminals.

Exception 1: The low-level signal connectors can be plugged into 120 V AC/230 V AC power terminals.

This connection error has no hazardous effect on the electrical components, but it can lead to system malfunctions.

Only the appropriate connectors should therefore be plugged into the low voltage power terminals.

Exception 2: The low-level signal connectors can be plugged into relay terminals. Because the relay outputs are floating, this connection error has no adverse effects.

3.3.5.3 Protection against the connection of live 120 V AC/230 V AC connectors in the 24 V DC area

If the connectors for the I/O terminals are wired according to the installation instructions, they are disconnected from the power supply when removed.

The following connectors may be live in the low voltage area:

1 Connectors of the power terminals for the 120 V AC and 230 V AC areas

2 Connectors for relay terminals

These connectors are closed using filler plugs in some places and therefore do not fit on the terminals of the 24 V area.

3.3.6 Response to the connection of a 120 V AC or 230 V AC terminal in the 24 V DC area

An AC terminal can be inserted in the 24 V DC area. The effects are described in Table 3-3.

A 24 V DC terminal cannot be inserted accidentally in an AC area as these terminals are not mechanically compatible.

AC power terminal in the 24 V DC area	Specified interface between a 24 V DC area and an AC area.The AC power terminal consists of two function parts:- The left-hand part interrupts the jumpering of U_S, U_M, GND , and FE- The connections for the power supply and the jumper contacts for L, N, and PE are on the right-hand part
Digital AC output terminal in the 24 V DC area	No direct danger to people.If the output is activated, the Triac output may be forced to trip and no longer switch off because the supply voltage does not pass through zero.NOTE: Possible malfunctionThis is likely to be caused by a malfunction of the actuator connected to the relevant output.
Digital AC input terminal in the 24 V DC area	No danger to people or machines.The input does not function due to missing ground.
Relay terminal in the 24 V DC area	No direct danger to people.The module has no diagonal routing, so there is no direct danger from the terminal, even with a 230 V connector. This means that the shortest isolating distance is the distance from one connector to the next. This isolating distance is not permitted. Therefore, insert a distance terminal (order designation IB IL DOR LV-SET) before and after the relay terminal.
AC end terminal in the 24 V DC area	No danger to people or machines.The terminal offers neither diagonal routing nor connector connection.

Inline ECO terminals enhance the Inline portfolio by inexpensive and especially simple terminals providing basic functionality. You can recognize these terminals by the "ECO" specified in the order designation. You can install Inline ECO terminals in series behind Inline bus couplers or Inline controllers, and combine them with standard terminals. Please note that if an Inline ECO terminal is used, the permissible ambient temperature for the station is limited to 0 °C to 55 °C.

Features of Inline ECO terminals

- No parameterization required (for digital and analog input and output terminals)

- Limited temperature range for operation: 0 °C ... 55 °C

– Scope of supply: electronics base and required connectors

- Analog and function terminals come without shield plug. For notes on shielding, please refer to Section “Connecting cables using Inline connectors” on page 123.

- Labeling fields are not included. For ordering data for labeling fields, please refer to the Section "Ordering data for accessories" on page 153.

4.2.2 Scope of supply

Depending on the type, Inline terminals are available with varying accessories. Type “-PAC” and “-ME” Inline terminals come with:

- The electronics base,

– all required Inline connectors, and

– all required labeling fields.

Inline connectors are designed for connecting the cables. They are required for correct operation of the terminal.

Labeling fields are used for clear marking. They are optional accessories.

In the past, Inline terminals were available as stand-alone items without accessories. For a stand-alone item without accessories, the Inline connectors have to be ordered separately.

If your item comes without labeling field, you can separately order labeling fields as optional accessories.

NOTE: Consequential damage

Protect the power supply externally, regardless of the power and/or segment terminal used.

Terminals that are not bus devices can be used in a local bus with 500 kbps as well as a local bus with 2 Mbps.

4.2.6.2 Power terminals

A power terminal is used to supply the required voltages to the internal station potential jumpers. Several power terminals can be used in one station. This means that different circuits can be electrically isolated and areas with different voltages can be created within the station (e.g., 24 V DC and 230 V AC).

All power terminals are used to supply the main voltage and/or segment voltage.

A 24 V supply voltage is also supplied at the IB IL 24 PWR IN/R-PAC and IB IL 24 PWR IN/PS-PAC terminals, from which the communications power U_L and the analog voltage U_ANA are generated. These terminals are mainly designed to boost the communications power and analog voltage when the maximum current carrying capacity of the potential jumpers for U_L/U_ANA or the maximum current carrying capacity of the bus coupler for U_L/U_ANA is reached.

Technical line drawing of a mechanical or electronic component with no visible text or symbols

Figure 4-3 Example of a power terminal: IB IL 24 PWR IN-PAC

Voltage areas

Depending on the power terminal, it is possible to work with 24 V DC, 120 V AC or 230 V AC within an Inline station.

To utilize different voltage areas within a station, a new power terminal must be used for each area.

WARNING: Dangerous contact voltage

When the power terminal is removed, the metal contacts are freely accessible. With 120 V AC or 230 V AC power terminals, it should be assumed that dangerous contact voltage is present. You must disconnect power to the station before removing a terminal.

If these instructions are not followed, there is a danger of damage to health or even of a life-threatening injury.

Observe safety notes

Observe the notes provided in Section “Important information about voltage areas” on page 15 when using voltages outside the SELV area.

IL SYS INST UM E

Potential jumpers	The power terminal interrupts all potential jumpers for the voltages to be reinjected, and recreates all potential jumpers (see also Section “Electrical potential and data routing (Inline Modular IO)” on page 73).
Carrying capacity of the jumper contacts	The maximum current carrying capacity of the jumper contacts on the side is specified in Section “Current and voltage distribution” on page 84.
Electrical isolation	The power terminal is used to create electrically isolated I/O areas within a station.
Functional earth grounding (24 V DC)	24 V power terminals are connected to functional earth ground when they are snapped onto the grounded DIN rail via the FE spring on the bottom of the terminal. This spring is connected to the FE potential jumper and to the terminal points for an FE connection.If the previous terminal is a 24 V terminal, the power terminal is connected to the FE potential jumper of the station when it is snapped onto this terminal.
Required additional functional earth grounding (24 V DC)	A 120 V AC and 230 V AC voltage level area interrupts the FE jumper, which is connected to FE via the additional functional earth grounding at the bus coupler. A 24 V DC power terminal that is at a different voltage area must therefore be reconnected to functional earth ground via the FE connection to ensure reliable functional earth grounding of the station even if the FE spring is dirty or damaged. Connect the terminal points for the FE connection to a grounded PE terminal (see Section “Grounding concept” on page 106).
Protective earth grounding(120 V AC/230 V AC)	The PE terminal point of the power connector connects the 120 V AC and 230 V AC power terminals to protective earth ground (PE). This terminal point is connected to the PE potential jumper, which is led through the entire 120 V AC or 230 V AC voltage area.
Additional documentation

For more detailed information about the function, properties, and wiring of the individual terminals, please refer to the terminal-specific documentation.

4.2.6.3 Segment terminals

Segment terminals can only be used in the 24 V DC area. Segment terminals can be used to create partial circuits (segment circuits) within the main circuit.

On segment terminals without a fuse, the connection between the main circuit U_M and the segment circuit U_S must be established using a jumper or a switch. Segment terminals with a fuse establish this connection automatically.

Technical line drawing of an electrical enclosure or switchgear component (no text or symbols visible)

Figure 4-4 Example of a segment terminal: IB IL 24 SEG-PAC

U_M The potential jumper for the main circuit U_M is not interrupted in the segment terminal. The potential for the segment circuit U_S is tapped from the potential jumper at the segment terminal.

U_S The segment terminal interrupts the segment circuit U_S in the potential jumper of the previous terminal.

For more detailed information about the supply voltages, please refer to Section "Circuits and provision of supply voltages" on page 73.

Carrying capacity of the jumper contacts The maximum current carrying capacity of the jumper contacts on the side is specified in Section "Current and voltage distribution" on page 84.

Functional earth grounding The terminal is connected to functional earth ground when it is snapped onto the grounded DIN rail via the FE spring on the bottom of the terminal. This spring is connected to the FE potential jumper and to the terminal points for an FE connection.

When snapped onto the previous terminal, the segment terminal is connected to the FE potential jumper of the station.

Additional documentation

For more detailed information about the function, properties, and wiring of the individual terminals, please refer to the terminal-specific documentation.

4.2.6.4 Accessory terminals

Potential distributor terminals and distance terminals are available as accessory terminals.

Potential distributor terminals (for GND and 24 V) are designed for the economical return wiring of sensor and actuator cables when using Inline terminals with 1-wire termination.

The distance terminal set creates the specified creepage distance when using AC terminals. Both distance terminals interrupt the potential jumpers for the main voltage, segment voltage, ground, and functional earth ground.

4.2.9 Safety modules

4.2.9.1 Bus-independent safety modules

IB IL 24 SAFE 2-ECO

The Inline ECO safety module with sensor circuits is designed for use within the 24 V area of an Inline station.

The module monitors two sensor circuits. The sensor circuits can be designed as single/two-channel, non-equivalent/equivalent.

If at least one sensor circuit is interrupted, the safety module initiates the safe state, and switches off the subsequent segment circuit for safety.

Possible signal generators

- Emergency stop button

– Safety door monitoring

- Light grid

Suitable up to category 4, PL e (EN ISO 13849-1), SILCL 3 (EN 62061)

Technical line drawing of an industrial electrical switchgear unit (no text or symbols)

Figure 4-10 Safety module IB IL SAFE 2-ECO

Safety-related segment circuit

The safety module can be used to create a safety-related segment circuit.

The structure of the safety-related segment circuit in the Inline system is such that actuators/controlled devices, which are connected to output terminals, can be switched separately via the bus system and can be switched off safely on a safety demand to the pre-connected safety module.

The safety-related segment circuit starts at a safety module and finishes at the last Inline terminal before another power supply unit or at the end of the station. Only Inline terminals that are specifically designed for the safety-related segment circuit may be used. They are listed in the "Safety-related segment circuit" application note, AH EN IL SAFE. Please also refer to the data sheet for the safety module in use.

4.2.9.2 Safety modules in a bus system with a safe protocol

In addition to the use of bus-independent, conventional safety modules (such as IB IL SAFE 2-ECO) in an Inline station, safety modules can also be used in a bus system with a safe protocol (SafetyBridge technology, PROFIsafe). In this type of bus system, the safe data is transmitted between the safe controller and the safety modules via the bus using a safe protocol. This means that the same cable is used for both safety-related communication and standard communication.

Technical line drawing of an electrical component with no visible text or symbols

Figure 4-11 Example of a safety module: IB IL 24 PSDO 8-PAC

SafetyBridge Technology

SafetyBridge Technology means that input and output modules exchange safety-related signals with each other. Since the modules process the safety functions themselves, they use the standard controller and network only for transport purposes.

Without a safety controller or safe fieldbus system, this is a cost-effective solution for functional safety in standard applications.

With SafetyBridge Technology, safety functions with the following requirements can be met: - up to category 4, PL e according to standard EN ISO 13849-1, - up to SILCL 3 according to standard EN 62061.

Within the Inline product group, the following safety modules, for example, are available for SafetyBridge Technology: - IB IL 24 LPSDO 8-PAC - IB IL 24 LPSDO 8 V2-PAC - IB IL 24 LPSDO 8 V3-PAC - IB IL 24 PSDI 8-PAC - IB IL 24 PSDI 16-PAC - IB IL 24 PSDO 8-PAC - IB IL 24 PSDO 4/4-PAC - IB IL 24 PSDOR 4-PAC

For detailed information, please refer to the module-specific user manuals.

PROFIsafe

PROFIsafe is a profile for PROFIBUS and PROFINET certified according to IEC 61508.

PROFIsafe can be used to achieve safety functions with the following requirements:

• up to category 4, PL e according to standard EN ISO 13849-1,
• up to SILCL 3 according to standard EN 62061.

Within the Inline product range, the following safety modules, for example, are available for PROFIsafe:

• IB IL 24 PSDI 8-PAC
• IB IL 24 PSDI 16-PAC
• IB IL 24 PSDO 8-PAC
• IB IL 24 PSDO 4/4-PAC
• IB IL 24 PSDOR 4-PAC

4.2.10 Programmable logic controllers (PLC)

Programmable logic controllers, so-called Inline controllers, are available for control tasks. Using an Inline Controller, the Inline station becomes a distributed control system. The Inline Controller integrates an IEC 61131-programmable PLC CPU in the Inline system. The Inline Controller enables direct signal processing of the distributed I/O points. The Inline Controller also enables the creation of independent subnetworks, which process automation tasks autonomously.

These branch terminals can be used to integrate sensors and actuators in close proximity to the station, which are connected to the Fieldline Modular M8 or M12 local bus with IP65/67 protection, in your bus system.

The terminal converts the physical transmission method of the Inline local bus to the physical transmission method of the Fieldline Modular local bus.

For additional information, please refer to the terminal-specific data sheet and the documentation for Fieldline Modular.

4.2.11.2 Local bus extension (jumping between two rows)

An Inline station can be extended by one or more rows. A combination of an IB IL 24 FLM-PAC branch terminal and an IB IL 24 LSKIP-PAC local bus extension terminal is used for this.

The branch terminal is installed at the end of a row of an Inline station and the local bus extension terminal is installed at the start of the following row.

The data is transmitted between the two terminals via the RS-422 protocol.

5 Structure and dimensions

5.1 Structure and dimensions of Inline Modular IO terminals

5.1.1 Basic structure of terminals in the 24 V DC and 120 V AC/230 V AC areas

Regardless of the function and design width, an Inline terminal for these voltage areas consists of the electronics base and the snap-on connector (Inline connector).

Figure 5-1 Basic structure of an Inline Modular IO terminal

ZBFM: Zack marker sheets, flat

(See also Section "Function identification and labeling" on page 53)

The components required for labeling are listed in the Phoenix Contact catalog.

5.1.2 Electronics base

	The electronics base holds the entire electronics for an Inline terminal and the potential and data routing.
Potential and data routing	Potential and data routing are located in the base. As all terminals are snapped onto the DIN rail, the position of the interfaces between the terminals in relation to the DIN rail is the same for all terminals. The advantage of this is that terminals of different sizes can be integrated into the station.The knife contacts are located on the left-hand side of the terminal (shown in Figure 5-1). They snap into the featherkeys of the next terminal on the left when the station is mounted.The type of routing contacts (i.e., potential or data) that are on each terminal depends on the function of the terminal and is shown in the circuit diagram of the relevant terminal-specific data sheet.
Snap-on mechanism/latching	Pressing the front and back snap-on mechanism at the same time releases the latching, enabling the terminal to be removed by pulling it straight back from the DIN rail (see Section “Basic information about mounting” on page 100).
Keyway/featherkey connection	The featherkeys are on the left-hand side of the terminal (Figure 5-1). They snap into the keyways of the next terminal on the left when the terminal is mounted on the DIN rail. The featherkeys are also referred to as locking clips and the keyways as guideways.
Base colors	The base and the appropriate connectors for the different voltage areas are of different colors (see Section “Electronics base and connectors for the different voltage areas” on page 19).

5.1.3 Connectors for terminals in the 24 V DC and 120 V AC/230 V AC areas

The I/O or supply voltages are connected using a pluggable connector. For more detailed information about the Inline connectors, please refer to Section 6, "Inline connectors".

5.1.4 Basic structure of power-level terminals

Power-level terminals are located in a power housing.

The power housing consists of the following parts:

Figure 5-2 Basic structure of Inline housing for power-level terminals

ZBFM: Zack marker sheets, flat

(See also Section "Function identification and labeling" on page 53)

The components required for labeling are listed in the Phoenix Contact catalog.

	The entire electronics for the Inline power-level terminal, the potential routing for the 24 V DC area, and the data routing are located in the power housing.
Potential and data routing	The potential and data jumpers that are led through the 24 V DC terminals are not interrupted by the power-level terminals. For more detailed information about the jumpers, please refer to Section “Electrical potential and data routing (Inline Modular IO)” on page 73.
Release flaps	Remove the power-level terminal from the DIN rail by pulling both release flaps (see Section “Mounting/removing power-level terminals” on page 117).
Keyway/featherkey connection	The featherkeys are on the left-hand side of the terminal (Figure 5-2). They snap into the keyways of the next terminal on the left when the terminal is mounted on the DIN rail.
	5.1.5 Connectors for power-level terminals
	The mains voltage, motor output, brake module, hand-held operator panel mode, and the enable power level/24 V isolation functions are connected via connectors.
Power connector/ power bridge/ cover	A power connector is available for supplying the mains voltage (IB IL 400 CN-PWR-IN).A power bridge is available for forwarding the mains voltage between power-level terminals (IB IL 400 CN-BRG).A cover is available for covering unused connections for the 400 V mains connection of the Inline power-level terminals (IB IL 400 CN-COV).
	Figure 5-3 Power connector, power bridge, and cover
Other connectors	All other connectors are connected using COMBICON or MINI-COMBICON connectors (see Phoenix Contact catalog).

Connector types

The following connector types are available for the 24 V DC area:

Technical line drawings of four mechanical components labeled A, B, C, D (no text or symbols on the parts themselves)

Figure 6-3 Connector types for Inline terminals

A S t a n d a r d c o n n e c t

The green standard connector is used for the connection of two signals in 4-wire technology or 8 signals in 1-wire technology (e.g., digital I/O signals).

The black standard connector is used to supply the supply voltage. Some of the adjacent contacts can be jumpered internally (see Figure 6-4 on page 66).

B Shield connector for connecting one cable

C Shield connector for connecting two cables

Green connectors B and C are used for signals connected using shielded cables (e.g., analog I/O signals, high-frequency counter inputs, remote bus cable).

FE or shielding is connected via a shield connection clamp rather than via a terminal point.

D Extended double signal connector

The green double signal connector is used for the connection of four signals in 3-wire technology (e.g., digital I/O signals).

The black double signal connector is used to supply the supply voltage. Some of the adjacent contacts can be jumpered internally (see Figure 6-4 on page 66).

Connector identification

All connectors are available with and without color print. The connectors with color print (indicated with CP in the order designation) have terminal points that are color-coded according to their functions. The following colors indicate the signals of the terminal points:

Table 6-1 Color-coding of terminal points (24 V DC)

Color Signal at terminal point
Red +
Blue -
Green Functional earth ground (FE)
Green/yellow Functional earth ground (FE);This marking may still be seen on older connectors. Functional earth ground is marked in green on modern connectors.

Internal jumpering

Depending on their function, the connectors may support internal jumpering.

NOTE: Disregarding this warning may result in malfunction

To avoid malfunction, only snap the connector onto an appropriate terminal. Refer to the relevant terminal-specific data sheet to select the correct connectors.

Only place black connectors on power or segment terminals.

When the terminal points are jumpered in the black connector, potential is routed through the jumpering in the connector and not through the printed circuit board of the terminal.

The complete current carrying capacity is ensured through this jumpering.

A black connector must not be placed on a terminal that is to be used for a double signal connector. Incorrect connection may lead to a short circuit between two signal terminal points.

6.4 Numbering and labeling of terminal points

Labeling/terminal numbering

Terminal point numbering is explained using the example of an 8-slot Inline Modular IO terminal.

Figure 6-6 Terminal point numbering

Slot/connector

The slots (connectors) on a base are numbered consecutively. This numbering is not indicated on the terminal (shown above the terminals in Figure 6-6).

Terminal point

Connectors are available with different forms of marking. In general, the numbering format X.Y is marked above the terminal point.

1 Terminal point numbering by connector (detail A in Figure 6-6):

On these connectors:

X: Number of the terminal point column on the connector.
Y: Number of the terminal point within the terminal point column.

2 Terminal point numbering by channel (detail B in Figure 6-6):

For terminals with 8, 16 or 32 I/Os, connector sets are available in which the terminal point rows are numbered by terminal (1 to 8) rather than by connector (1 and 2).

X: Number of the terminal point column on the Inline terminal.
Y: Number of the terminal point within the terminal point column.

Select the necessary connectors from the Phoenix Contact catalog.

Additional labeling

In addition to this connector marking, you can identify the slots, terminal points, and connections using Zack marker strips and labeling fields.

Figure 6-7 Labeling

Various options are available for labeling the slots and terminal points:

1 Each connector can be labeled individually using Zack marker strips. 2/3 Another option is to use a labeling field. Labeling fields are available in two widths, either as a labeling field covering one connector (2; IB IL FIELD 2) or as a labeling field covering four connectors (3; IB IL FIELD 8). You can label each channel individually with free text. On the upper part of the connector there is a keyway for attaching this labeling field. The labeling field can be tilted up and down. In each end position a light latching ensures that the labeling field remains in place.

4/5 Each signal can be labeled individually using Zack marker strips. On a double signal connector, the upper keyway (4) is designed for labeling signals 1 and 2 and the lower keyway (5) is for signals 3 and 4.

6 On the electronics base, each slot can be labeled individually using Zack marker strips. These marker strips are covered when a connector is plugged in.

Using the marker strips on the connector and on the electronics base, you can clearly assign both connector and slot.

Insert strips for use with a laser printer are available for insertion in the IB IL FIELD 2 and IB IL FIELD 8 labeling fields (see Section "Ordering data for accessories" on page 153).

The components required for labeling are listed in the Phoenix Contact catalog.

6.5 Terminal point keying

In order to prevent connectors being mixed up, the connection points between connectors and terminals can be keyed using the IL CP keying profile.

Figure 6-8 Connector and terminal keying

A 1. Insert a keying section of the keying profile in the corresponding keyway of the terminal point on the electronic housing.

1. Twist the keying profile to break off the keying section.

B Remove the keying tab from the corresponding slot keying on the connector.

C Insert the keyed connector in the corresponding slot.

7 Electrical potential and data routing (Inline Modular IO)

The Project+ software provides support when configuring an Inline station (see Section "Appendix: Software support" on page 169).

7.1 Circuits and provision of supply voltages

There are several circuits within an Inline station. These are automatically created when the terminals are properly installed. The voltages of the different circuits are supplied to the connected terminals via potential jumpers.

An example of the circuits within an Inline station is given in Section "Example of a circuit diagram" on page 78. The descriptions in the following sections refer to this example.

Please refer to the terminal-specific data sheet for the circuit to which the I/O circuit of a specific terminal is to be connected.

Carrying capacity of the jumper contacts

Observe the maximum current carrying capacity of the jumper contacts on the side for each circuit. The current carrying capacities for all potential jumpers are given in the following sections and are summarized in Section "Current and voltage distribution" on page 84.

For the arrangement of the potential jumpers and information about current and voltage distribution on the potential jumpers, please refer to Section “Electrical potential and data routing” on page 80.

The connection of the supply voltages is described in Section “Connecting the power supplies” on page 128.

For voltage connection, please observe the notes in the terminal-specific data sheets.

7.1.1 Bus coupler supply

Please refer to the documentation for your bus coupler to determine the correct supply voltage for the bus coupler.

The voltages for the logic circuit U_L and the supply of the terminals for analog signals U_ANA are always internally generated from the bus coupler supply.

7.1.2 Logic circuit

The logic circuit with the communications power U_L starts at the bus coupler or at a power terminal (IB IL 24 PWR IN/R-PAC; IB IL 24 PWR IN/PS-PAC) and is led through all the terminals of an Inline station.

Function The logic circuit (e.g., protocol chip, microcontroller) of the devices in a station is supplied with voltage from the logic circuit.

Voltage The voltage in this circuit is 7.5 V DC ±5%.

Provision of U_L The communications power U_L is provided by the bus coupler or a corresponding power terminal from the connected supply voltage.

Current carrying capacity The maximum current carrying capacity is 2 A. If this value is reached, the voltage must be boosted via a power terminal or a new station must be created using a bus coupler.

The current consumption from the logic circuit of each device is specified in the DB GB IB IL DEVICE LIST data sheet and the relevant terminal-specific data sheet.

The communications power is not electrically isolated from the 24 V DC input voltage for the bus coupler.

This maximum current carrying capacity can be limited by certain bus couplers or corresponding power terminals. Please refer to the information in the terminal-specific data sheets.

7.1.3 Analog circuit

The analog circuit with the supply for the analog terminals (also referred to as analog voltage) U_ANA starts at the bus coupler or at a power terminal (IB IL 24 PWR IN/R-PAC; IB IL 24 PWR IN/PS-PAC) and is led through all the terminals of an Inline station.

Function The I/O for analog signal terminals is supplied from the analog circuit.

Voltage The voltage in this circuit is 24 V DC (+20%, -15%).

Provision of U_ANA The analog voltage U_ANA is provided by the bus coupler or a corresponding power terminal from the connected supply voltage.

Current carrying capacity The maximum current carrying capacity is 0.5 A. If this value is reached, the voltage must be boosted via a power terminal or a new station must be created using a bus coupler.

The current consumption from the analog circuit of each device that is supplied from U_ANA is specified in the DB GB IB IL DEVICE LIST data sheet and the relevant terminal-specific data sheet.

7.1.4 Main circuit

The main circuit with the main voltage U_M starts at the bus coupler or a power terminal and is led through subsequent terminals until it reaches the next power terminal.

Please note the special requirements of Inline terminals with relay outputs. These terminals interrupt the potential jumpers U_M and U_S .

A new circuit starts at the next power terminal. This circuit is electrically isolated from the previous one if electrically isolated power supply units are used.

Several power terminals can be used within one station.

Function The segment voltage U

U_S can be tapped from the main voltage U_M using different segment terminals. Several independent segments can thus be created within the main circuit. The main circuit provides the supply voltage for these segments.

Some terminals access the main circuit directly. For example, the encoder supply for positioning terminals is tapped from the main circuit, while the I/O is supplied from the segment circuit.

Voltage The voltage in this circuit must not exceed 30 V DC.

Current carrying capacity

The maximum current carrying capacity for the main circuit is 8 A (total current with the segment circuit).

This maximum current carrying capacity can be limited by certain terminals. Please refer to the information in the terminal-specific data sheets.

If the limit value of the potential jumpers U_M and U_S is reached (total current of U_S and U_M ), a new power terminal must be used.

Provision of U_M

In the simplest case, the main voltage U_M can be supplied at the bus coupler.

The main voltage U_M can also be supplied via a power terminal. A power terminal must be used if:

1 A bus coupler that cannot supply the main voltage is used.
2 Different voltage areas (e.g., 24 V DC and 120 V AC) are to be created.
3 Electrical isolation between different I/O areas is to be created.
4 The maximum current carrying capacity of the potential jumpers U_M , U_S , and GND (total current of U_S and U_M ) is reached.

7.1.5 Segment circuit

The segment circuit with segment voltage U_S starts at the bus coupler or a power or segment terminal and is led through the subsequent terminals until it reaches the next power or segment terminal.

Please note the special requirements of Inline terminals with relay output. These terminals interrupt the potential jumpers U_M and U_S .

You can use several segment terminals within a main circuit and therefore segment the main circuit.

Function

Almost all the terminals in the Inline station except the analog terminals are supplied from the segment circuit (e.g., digital input terminals, digital output terminals).

The segment circuit also provides the auxiliary voltage for controlling circuit breakers and contactors.

Some terminals access both the segment circuit and the main circuit. For example, the encoder supply for positioning terminals is tapped from the main circuit, while the I/O is supplied from the segment circuit.

The segment circuit can be switched off or fused using the safety or segment terminals. It has the same reference ground as the main circuit. This means that circuits with different fuses can be created within the station without external cross-wiring.

Voltage The voltage in this circuit must not exceed 30 V DC.

Current carrying capacity

The maximum current carrying capacity for the segment circuit is 8 A (total current with the main circuit).

This maximum current carrying capacity can be limited by certain terminals. Please refer to the information in the terminal-specific data sheets.

If the limit value of the potential jumpers U_M and U_S is reached (total current of U_S and U_M ), a new power terminal must be used.

Provision of U_S

There are various ways of providing the segment voltage U_S :

1 The segment voltage can be supplied at the bus coupler or a power terminal.
2 The segment voltage can be tapped from the main voltage at the bus coupler or a power terminal using a jumper or a switch.
3 An IB IL 24 PWR IN/2-F...-PAC power terminal with fuse for the main and segment circuit or a segment terminal with fuse for the segment circuit can be used. In these terminals the segment voltage is automatically tapped from the main voltage.
4 A segment terminal can be used without a fuse and the segment voltage can be tapped from the main voltage using a jumper or a switch.

The creation of segments is not possible for the 120 V AC and 230 V AC voltage levels. Here, only one circuit is used, which corresponds to the main circuit.

7.1.6 Mains voltage for power-level terminals

The mains voltage for power-level terminals is not provided via the potential jumpers. It is either supplied to the power-level terminal via a power connector or led between directly adjacent power-level terminals via power bridges.

Voltage The mains voltage must have the following values:

IB IL 400 ELR ... IB IL 400 MLR ...

Nominal voltage during operation (conductor voltage) 400 V AC 400 V AC

Voltage range 187 V AC ... 440 V AC + 0% with safe isolation between mains and SELV 187 V AC ... 519 V AC + 0% with safe isolation between mains and SELV;

187 V AC ... 600 V AC + 0% with basic insulation between mains and SELV

Frequency The frequency of the mains voltage must be 50 Hz or 60 Hz.

Current carrying capacity The maximum current carrying capacity for the incoming mains must be 20 A. If this value is reached, it must be reinjected.

7.1.7 Example of a circuit diagram

Main circuit M1/segment S1.1

The supply voltage for the bus coupler U_BK is supplied at the bus coupler (BK). In addition, the main voltage U_M1 is supplied at the bus coupler or a subsequent power terminal.

The communications power U_L and the supply voltage for the analog terminals U_ANA are generated from the bus coupler supply and led through the entire station.

Electrical isolation between logic and I/O is created through the separate supply of the bus coupler supply U_BK and the main voltage U_M1 .

If these voltages are not supplied separately (e.g., only the voltage U_M1 , from which U_L and U_ANA are also generated), there is no electrical isolation between logic and I/O.

No terminals are used in segment S1.1.

Segment S1.2 In a segment terminal with fuse, the segment voltage U S for segment S1.2 is automatically tapped from the main voltage U M1 . This segment circuit is protected by the internal fuse.

This segment terminal has been specifically used to create a protected segment circuit without the need for an additional external fuse. If this is not necessary, the terminal does not have to be used. In this case, the connection between U_M and U_S on the bus coupler must be established using a jumper (as shown on the IB IL 24 PWR/IN-PAC terminal) or a switch (as shown on the IB IL 24 SEG-PAC terminal).

Main circuit M2/segment S2.1

The supply voltage for the power-level terminals and the subsequent terminals should be supplied separately. For this, a new power terminal (e.g., IB IL 24 PWR/IN-PAC) is used, which supplies the supply voltage U_M2 .

Using a jumper, the segment voltage U_S for segment S2.1 is tapped from the main voltage U_M2 at this terminal.

Segment S2.2 The segment voltage U _S is provided at the IB IL 24 SEG-PAC segment terminal via a switch. Output terminals installed here can therefore be switched externally.

Examples of errors and their effects:

1 In this example structure, a short circuit in segment S1.2 would not affect the terminals in other segments. The fuse in the IB IL 24 SEG/F-PAC segment terminal means that only segment S1.2 is switched off.
2 If an error occurred in the system, the terminals in segment S2.2, for example, could be switched on or off without affecting the terminals in other segments.

7.2 Electrical potential and data routing

7.2.1 Arrangement of potential and data jumpers

An important feature of Inline is its internal potential routing system. The electric connection between the individual station devices is created automatically when the station is installed. When the individual station devices are connected, a power rail is created for the relevant circuit. Mechanically, this is created by interlocking knife and featherkey contacts from the adjacent terminals.

This potential routing eliminates the need for additional external potential routing or cross-wiring.

The 400 V AC mains voltage for power-level terminals is not led via the internal station potential routing. It is supplied via a power connector and is led between two power-level terminals via power bridges.

Terminal inputs and outputs are supplied with voltage via the segment circuit.

The voltage for the segment circuit can be tapped from the main circuit. In addition, some terminals tap the voltage directly from the main circuit.

For more detailed information about the circuits that are created via the potential jumpers U_L , U_ANA , U_M , and U_S , please refer to page 73.

Depending on the terminal function, not all of the jumpers listed in Figure 7-2 are present on a terminal. Please refer to the circuit diagram of the terminal to see which jumpers are available for a terminal and how they are internally connected. The circuit diagram is shown in the terminal-specific data sheet.

GND

(24 V DC area)

This potential jumper is ground for the main and segment circuits.

NOTE: Overload

Please note that the GND potential jumper carries the total current of the main and segment circuits. The total current of the main and segment circuits must not exceed the maximum current carrying capacity of the potential jumpers (8 A). The maximum current carrying capacity is determined not only by the potential jumpers, but also by the power/segment terminal used.

Calculate the current in the station. Refer to the data provided in the terminal-specific data sheets for your particular application.

The Project+ software provides support when calculating the currents (see Section "Appendix: Software support" on page 169).

FE

(24 V DC area)

The FE potential jumper is connected to the grounded DIN rail via the FE spring at each bus coupler, each 24 V power terminal, and each segment terminal and is led through all subsequent 24 V terminals.

In addition, connect the FE connection to a grounding terminal at the bus coupler.

If the FE jumper is interrupted by a 120 V AC/230 V AC voltage level, reconnect the FE connection to a grounding terminal at the subsequent 24 V DC power terminal.

Please also observe the information in Section "Grounding concept" on page 106.

FE spring

(24 V DC area)

This spring creates the FE contact between the bus coupler, a 24 V DC power terminal or a segment terminal, and the grounded DIN rail.

Data routing

(all areas)

The bus signal is also transmitted within the station using a connection that is created automatically when the station devices are snapped on.

Current carrying capacity

(all areas)

The maximum total current flowing through the potential jumpers is limited. The maximum current carrying capacity for each circuit is specified in Section "Circuits and provision of supply voltages" on page 73.

Please also observe the information about the current carrying capacity of the power and segment terminals provided in the terminal-specific data sheets.

NOTE: Malfunctions

If the current carrying capacity of the potential jumpers U_L or U_ANA is reached, the voltage must be boosted via a power terminal, or a new station must be created using a bus coupler

If the current carrying capacity of the potential jumpers U_M, U_S , and GND is reached (total current of U_S and U_M ), a new power terminal must be used.

The Project+ software provides support when calculating the currents (see Section "Appendix: Software support" on page 169).

8 Diagnostic and status indicators

	All Inline Block IO modules and Inline Modular IO terminals (referred to below as the device) are equipped with diagnostic and status indicators for quick local error diagnostics. They enable the clear localization of system errors (bus errors) or peripheral faults.
Diagnostics	The diagnostic indicators (red, yellow or green) provide information about the state of the device and, in the event of an error, provide information about the type and location of the error. The device is operating correctly if all of its green LEDs are on.
Status	The status indicators (yellow) indicate the status of the relevant input/output and the connected I/O device.
Extended diagnostics	Some devices have extended diagnostics. A short circuit or overload of the sensor supply is indicated for each input. If a short circuit occurs at an output, each channel is diagnosed individually. Information about the supply voltage is also reported. Information about peripheral faults is sent to the control system with precise details of the error type and is displayed using status indicators.
	For information about the diagnostic and status indicators on a specific device, please refer to the device-specific data sheet.
	8.1 Indicators on Inline Modular IO terminals
	8.1.1 Indicators on bus couplers and terminals with remote bus branch
	For the meaning of the diagnostic and status indicators of the bus coupler and the terminals with remote bus branch, please refer to the corresponding documentation.

8.1.2 Indicators available on different terminals in the Inline system

Some indicators can be found on various terminals (see section below) and generally have the same meaning:

UM Green LED Supply in the main circuit
ON: Supply present in the main circuit
OFF: Supply not present in the main circuit
US Green LED Supply in the segment circuit
ON: Supply present in the segment circuit
OFF: Supply not present in the segment circuit
D Green LED Diagnostics
ON: Data transmission active within the station
Flashing:
0.5 Hz:(slow)	Communications power present, data transmission not active within the station
2 Hz:(medium)	Communications power present, peripheral fault (e.g., fuse has blown, voltage not present)
4 Hz:(fast)	Communications power present, error at the interface between previous and flashing terminal (the terminals after the flashing terminal cannot be addressed). (E.g., loose contact at the bus interface, terminal before the flashing terminal has failed, another terminal was snapped on during operation (not permitted))
OFF: Communications power not present

8.1.3 Indicators on power and segment terminals

Figure 8-1 Possible indicators on power and segment terminals
Diagnostics The following states can be read on power and segment terminals:

Power terminal
UM (1)	Green LED	Supply voltage in the main circuit (for meaning see page 88)
Segment terminal
US (1)	Green LED	Supply voltage in the segment circuit (for meaning see page 88)
Power terminal with fuse and diagnostics/segment terminal with electronic fuse
D (3) Green LED Diagnostics (for meaning see page 88)
Also on terminals with fuse
E (2) Red LED Fuse status

On terminals with fuses, the green UM or US LED indicates that the main or segment voltage is present on the line side of the fuse, meaning that if the green LED is on, there is voltage on the line side of the fuse. If the red E LED is also on, the fuse has blown or is missing and no voltage is applied after the fuse.

If the red E LED is on and the green D LED is flashing at 2Hz on terminals with fuse and diagnostics, there is no voltage present after the fuse. Thus, a blown fuse is indicated by both diagnostic indicators (E and D).

8.1.4 Indicators on I/O terminals

In this section, I/O terminals are all terminals that acquire or output signals, i.e., all terminals excluding bus couplers, power, segment, and power-level terminals.

The LEDs of the I/O terminals are electrically located in the logic area. This may mean that the LED of an output is on but the output cannot be controlled due to an error between the logic area and the digital output. The LED does not monitor the output state. In the event of an error, the actual output state may differ from the state indicated by the LED.

Figure 8-2 Indicators on I/O terminals

Diagnostics The following states can be read on I/O terminals:

D(1)	Green LED Diagnostics (for meaning see page 88)

8.2.3 Indicators in the I/O function area (IN, OUT, IN/OUT)

The LEDs of the I/O function area are electrically located in the logic area.

This may mean that the LED of an output is on but the output cannot be controlled due to an error between the logic area and the digital output. The LED does not monitor the output state. In the event of an error, the actual output state may differ from the state indicated by the LED.

For every module, the assignment is specified in the module-specific data sheet.

9 Mounting/removing devices

9.1 Installation instructions

9.1.1 Unpacking

ESD regulations

NOTE: Electrostatic discharge

The devices contain components that can be damaged or destroyed by electrostatic discharge. When handling the devices, observe the necessary safety precautions against electrostatic discharge (ESD) according to EN 61340-5-1 and IEC 61340-5-1.

Unpacking

All devices are supplied in an ESD bag.

Only qualified personnel should pack, unpack, mount, and remove the device while observing the ESD regulations.

9.1.2 Replacing a device

When replacing a device, please observe the following.

- In the SELV area:

NOTE: Disregarding this warning may result in malfunction

Do not replace devices while the power is connected.

Inline Modular IO:

Before removing or mounting a terminal, disconnect power to the entire station.

Make sure the entire station is reassembled before switching the power back on.

– In the low voltage area (Inline Modular IO):

WARNING: Dangerous contact voltage

Do not replace devices while the power is connected.

Before removing or mounting a terminal, disconnect power to the entire station.

Make sure the entire station is reassembled before switching the power back on.

9.2 Basic information about mounting

Mounting location

Modules and terminals of the Inline product range have IP20 protection and are therefore designed for use in a closed control cabinet or control box (terminal box) with IP54 protection or higher.

DIN rail

All Inline Block IO modules and Inline Modular IO terminals are mounted on 35 mm standard DIN rails.

The modules are mounted perpendicular to the DIN rail. This ensures that they can be easily mounted and removed even when space is at a premium.

The distance between DIN rail fasteners must not exceed 200 mm. This distance is necessary for the stability of the rail when mounting and removing devices.

Figure 9-1 Fixing the DIN rail (in mm)

Mounting position

No specific mounting position is specified for the Inline Block IO modules or Inline Modular IO terminals. However, please refer to the ambient temperatures and any other special requirements (such as derating) specified in the data sheets.

Analog terminals are a special case. The accuracy data specified in the data sheets for these devices refers to the documented mounting position (usually horizontal DIN rail; Figure 9-2, detail A). The typical tolerance values for the relevant configurations are determined in this mounting position. Experience from previous testing indicates that the typical tolerances of analog terminals are slightly affected by the mounting position. This means that another mounting position is also possible in principle.

To ensure sufficient mechanical fixing for the Inline station or Inline Block IO module when mounting on a vertical DIN rail (Figure 9-2, detail B), we recommend the E/AL-NS 35 end clamp. This prevents the station or module from slipping down, particularly in the event of vibration.

B

Figure 9-2 Mounting positions for an Inline station

9.3 Mounting distances

The space required for cable routing depends on the number of cables to be installed and must be left free on the left and/or right-hand side.

In order to minimize the parallel installation of signal and power supply lines, the cable duct on the left can be used for the signal and bus lines, for example, and the duct on the right for the power supply lines. This ensures that the parallel installation of these cable types is kept to a minimum and limits interference on the signal lines.

For the distances of the upper and lower cable ducts or the cable routing to the devices, please refer to the sections below.

9.3.1 Mounting distances for Inline Modular IO terminals

9.3.1.1 Mounting distances for terminals in the 24 V DC, 120 V AC, and 230 V AC areas (excluding terminals with fiber optic connections)

Figure 9-3 Mounting distances for terminals in the 24 V DC, 120 V AC, and 230 V AC areas

If the distances are smaller, the minimum bending radius of the cables, easy handling during installation, and a clear structure cannot be guaranteed.

9.3.1.2 Mounting distances for terminals with fiber optic connections

The bending radius and the space required for mounting terminals with fiber optic connections depends on the fiber optics used. Furthermore, the connector that is used affects the mounting distances.

Observe the instructions in the "IBS SYS FOC ASSEMBLY" fiber optic installation guidelines when determining the mounting distances.

According to the guidelines valid at the time of publication (Revision 03, 01/2007) the minimum bending radius for individual wires is 30 mm, and the minimum bending radius for a cable is either 50 mm or 65 mm depending on the cable. Using a fast connection connector with bend protection, for example, results in the following mounting distances:

Figure 9-4 Example mounting distances for the IBS IL 24 BK-LK-PAC bus coupler when using individual wires (bending radius 30 mm)

9.3.1.3 Mounting distances for power-level terminals

NOTE: Overheating

The minimum vertical mounting distances shown in Figure 9-5 must be observed for power-level terminals to ensure sufficient ventilation of the power-level terminals.

Ensure additional space for installing the cables.

Figure 9-5 Mounting distances for power-level terminals

9.3.1.4 Mounting distances for mounting outside a terminal box

If the Inline stations are housed, e.g., in a control cabinet rather than a terminal box, the DIN rail distances depend on the previously specified mounting distances and the particular configuration of the individual Inline stations. The possible mounting distances are shown in Figure 9-6.

Figure 9-6 Mounting distances for mounting outside the terminal box for different station structures

9.3.2 Mounting distances for Inline Block IO modules

Figure 9-7 Mounting distances (in mm)

If the distances are smaller, the minimum bending radius of the cables, easy handling during installation, and a clear structure cannot be guaranteed.

9.4 Grounding concept

Within an Inline station, a distinction is made between functional earth ground (FE) and protective earth ground (PE).

For Inline Block IO modules, only functional earth grounding is used.

Protective earth grounding (PE)

Protective earth grounding protects people and machines against hazardous voltages. To avoid these dangers, correct installation, taking the local conditions into account, is vital.

Functional earth grounding (FE)

Functional earth grounding is used to improve noise immunity. All devices must be grounded so that any possible interference from data transmission paths is shielded and discharged to ground.

A 1.5 mm ^2 wire must be used for grounding spring-cage terminals.

9.4.1 Functional earth ground (FE)

Functional earth ground is a low-impedance current path between circuits and ground. It is not designed as a safety measure but rather, for example, for the improvement of noise immunity.

Functional earth ground (FE) is only used to discharge interference. It does not provide shock protection for people.

Functional earth ground is used within the 24 V DC area (SELV).

To ensure reliable functional earth grounding of the station, various points must be observed.

Inline Modular IO

For Inline Modular IO terminals, functional earth ground is led from the grounded bus coupler through the 24 V DC area of the station using the FE potential jumper.

1 The bus coupler, power terminals, and segment terminals have an FE spring (metal clip) on the bottom of the electronics base. This spring establishes an electrical connection to the DIN rail. Use grounding terminals to connect the DIN rail to protective earth ground. The terminals are grounded when they are snapped onto the DIN rail.

2 Phoenix Contact also recommends grounding the Inline Modular IO bus coupler via the FE terminal point of the corresponding connector to ensure reliable functional earth grounding even if the DIN rail is dirty or the metal clip is damaged (see terminal-specific data sheet).

3 A 120 V AC or 230 V AC voltage area interrupts the FE potential jumper. Therefore, a 24 V DC power terminal, which is installed directly after such an area, must also be grounded via the FE terminal point (see terminal-specific data sheet).

Any additional Inline low-level signal terminals are automatically grounded via the FE potential jumper when they are properly installed.

The FE potential jumper is looped through the power-level terminals.

Illustration of an industrial control unit with wiring and connector (no text or symbols)

Figure 9-8 Additional functional earth grounding of a bus coupler (Example: IL PB BK DI8 DO4-PAC)

Figure 9-8 shows the additional grounding for a bus coupler using the example of the IL PB BK DI8 DO4-PAC bus coupler. Connect the additional grounding to your device according to the terminal-specific documentation.

Inline Block IO

1 The modules have an FE spring (metal clip) on the bottom of the electronics base. This spring establishes an electrical connection to the DIN rail. Use grounding terminals to connect the DIN rail to protective earth ground. The modules are grounded when they are snapped onto the DIN rail.
2 Phoenix Contact also recommends grounding the Inline Block IO module via the FE terminal point of the corresponding connector to ensure reliable functional earth grounding even if the DIN rail is dirty or the metal clip is damaged (see terminal-specific data sheet).

9.4.2 Protective earth ground (PE) (Inline Modular IO)

Protective earth ground is a low-impedance current path that minimizes the risk to the operator in the event of an error (including a high voltage and/or current error between an electrical circuit and ground).

In Inline terminals, protective earth ground is used outside the SELV.

WARNING: Disregarding this warning may result in the loss of electrical safety

Every power terminal of the 120 V AC or 230 V AC area must be connected to the DIN rail with low impedance, otherwise no protection is provided.

The PE (protective earth ground) potential jumper is led from the power terminal of the 120 V AC or 230 V AC area through this entire area to the next power terminal.

Power-level terminals are connected to PE using the power connector and voltage continuation between power-level terminals is ensured using the power bridge.

Illustration of an industrial control unit with wiring and connectors (no text or symbols)

Figure 9-9 Additional grounding of a bus coupler and protective earth ground connection (Example: IL PB BK DI8 DO4-PAC)

Figure 9-9 shows the additional grounding and protective earth ground connection using the example of the IL PB BK DI8 DO4-PAC bus coupler. Connect the additional grounding and protective earth ground to your devices according to the terminal-specific documentation.

9.5 Shielding concept

Shielding is used to reduce the effects of interference on the system.

9.5.1 Inline shielding concept

In the Inline system, shielded cables are used with the following terminals:

• Remote bus cables

• Connecting cables

• At terminals for analog signals (analog input, analog output, temperature recording)

• At terminals for open and closed-loop control
• At communication terminals
• At detection terminals
• At programmable terminals

Observe the following points when installing shielding:

• Secure the shielding so that as much of the braided shield as possible is held underneath the clamp of the shield connection.
• Make sure there is good contact between the connector and base.
• Do not damage or squeeze the wires.
• When connecting the shielding, observe the specifications for the connector wiring.

9.5.2 Shielding when connecting analog sensors and actuators

• Always connect analog sensors and actuators with shielded, twisted pair cables.
• Connect the shielding via the Inline connector with shield connection (see Section "Connecting shielded cables using an Inline shield connector" on page 124).

When connecting the cables, observe the instructions in the terminal-specific data sheets.

• As a rule, shielding must only be connected directly to the PE potential on one side. This is to prevent any occurrence of voltage equalization currents via the shielding.
• If necessary, integrate the shielding concept for analog I/O cables into the system concept, for example, it is useful to use a central FE shield connection at the control cabinet entry.

Example: Integration of analog shielding in a concept with central equipotential bonding at the control cabinet entry

Figure 9-10 Integration of analog shielding in a concept with central equipotential bonding at the control cabinet entry

1 Lead the analog cable into the Inline connector making sure to maintain the cable insulation.
2 Use shielded twisted pair cables.
3 Connect the strain relief directly to PE potential. Connect the shield for the entire analog transmission path to PE potential at just one point. In the example above, this point is the jumpering level (C).
4 Lead the sensor cable into the sensor making sure to maintain the cable insulation.

NOTE: Possible malfunctions

When integrating the shielding of analog I/O cables in an equipotential bonding concept, make sure that direct connection to the PE potential is only made at one point (e.g., at the central grounding point of the jumpering level).

9.6 Mounting/removal

9.6.1 Inline Modular IO: Mounting/removal

Mounting side by side (Inline Modular IO)	An Inline station is set up by mounting the individual components side by side. No tools are required. Mounting the components side by side automatically establishes the potential and bus signal connections between the individual station components.After a station has been set up, individual terminals can be exchanged by pulling them out or plugging them in. Tools are not required.
End clamps (Inline Modular IO)	Mount end clamps on both sides of the Inline station. The end clamps ensure that the Inline station is correctly mounted. End clamps secure the Inline station on both sides and keep it from moving from side to side on the DIN rail. For the recommended end clamps, please refer to Section “Ordering data” on page 153.When mounting on a horizontal DIN rail, the end clamps can be snapped onto the DIN rail at any point during station assembly.When mounting on a vertical DIN rail, secure the end clamp on the left at the start of station assembly, so as to prevent the station from slipping down.
End plate (Inline Modular IO)	The end plate terminates an Inline station. It has no electrical function. It protects the station against ESD pulses and the user against dangerous contact voltages. The end plate is supplied with the bus coupler and does not have to be ordered separately.
Order of the Inline terminals	When mounting, observe the correct order of the Inline terminals (see Section “Order of the Inline Modular IO terminals” on page 120).

9.6.1.1 Mounting/removing/replacing terminals in the 24 V DC and 120 V AC/230 V AC areas

Mounting

When mounting a terminal in these areas, proceed as shown in Figure 9-11 on page 113:

• Disconnect the power to the station.
• First snap on the electronics base, which is required for mounting the station, perpendicular to the DIN rail (detail A).

When doing this ensure that all featherkeys and keyways on adjacent terminals are securely interlocked (detail B).

The keyway/featherkey connection links adjacent terminals together and ensures that data and potential routing is created safely.

- First, insert the data jumper for the bus interface in the guideways by snapping it onto the previous terminal (detail B1).

NOTE: Malfunction in the event of no contacting

Press gently against the adjacent terminal on the left to make sure that the featherkey has snapped into its keyway on the bus interface.

• Then insert the other potential jumpers into their guideways and snap the featherkeys into the corresponding keyways (detail B2).
• Detail C1 shows a common error. Here, the bus interface has not contacted properly. The featherkey is not in the keyway. The bus is not running or is running with errors ("loose contact").
• Detail C2 shows secure contacting of the data jumpers and the interlocking keyway/featherkey connection.

- Once all the bases have been snapped on, plug the connectors into the appropriate bases.

First, place the front connector shaft latching in the front snap-on mechanism (detail D1).

Then press the top of the connector towards the base until it snaps into the back snap-on mechanism (detail D2).

The keyways of an electronics base do not continue on a connector. When snapping on an electronics base, there must be no connector on the left-hand side of the base. If a connector is present, it will have to be removed.

Removal

When removing a terminal, proceed as shown in Figure 9-12 on page 114:

• Disconnect the power to the station.
• If there is a labeling field, which covers several connectors, it may have to be removed (detail A1).

If a terminal has several connectors, all connectors of the terminal must be removed. The following describes how a 2-slot terminal is removed.

- Lift the connector of the terminal to be removed by pressing on the back connector shaft latching (detail A2).

When using extended double signal connectors (long connectors), please ensure that you do not bend them back too far, as you may break the front snap-on mechanism.

• Remove the connector (detail B).
• Remove the adjacent connectors of the neighboring terminals (detail C). This prevents the potential routing knife contacts and the keyway/featherkey connections from being damaged. You also have more space available for accessing the terminal.

- Press the snap-on mechanism (detail D1), and remove the electronics base from the DIN rail by pulling the base straight back (detail D2). If you have not removed the connector of the adjacent terminal on the left, remove it now in order to protect the potential routing knife contacts and the featherkeys of the keyway/featherkey connection.

Figure 9-12 Removing a terminal

Replacing a terminal

If you want to replace a terminal within the Inline station, follow the removal procedure described above. Do not snap the connector of the adjacent terminal on the left back on yet. Insert the base of the new terminal.

When doing this ensure that all featherkeys and keyways on adjacent terminals are securely interlocked.

Then reconnect all the connectors.

The top connector latching must click into place.

9.6.1.2 Replacing a fuse

The 24 V DC power and segment terminals are also available in versions with a fuse. If a fuse is not present or faulty, you must insert or replace it.

WARNING: Observe the following notes when replacing a fuse for the protection of your health and your system.

1. Use the screwdriver carefully to avoid injury to yourself or other persons.
2. Lift the fuse out at the metal contact. Do not lift the fuse out at the glass part as this may break it.
3. Carefully lift the fuse out at one side and remove it by hand. Make sure the fuse does not fall into your system.

When replacing a fuse, proceed as shown in Figure 9-13 on page 116:

• Lift the fuse lever (detail A).
• Insert the screwdriver behind a metal contact of the fuse (detail B).
• Carefully lift out the metal contact of the fuse (detail C).
• Remove the fuse by hand (detail D).
• Insert a new fuse (detail E).
• Push the fuse lever down again until it clicks into place (detail F).

9.6.1.3 Mounting/removing power-level terminals

Observe the following safety notes and warning instructions when working on power-level terminals.

WARNING: Dangerous contact voltage

Only work on power-level terminals and connectors when the power is disconnected.

Observe the safety notes and warning instructions provided in the terminal-specific data sheets.

Mounting

When mounting a power-level terminal, proceed as shown in Figure 9-14:

- Snap on the power housing, which is required for mounting the station, perpendicular to the DIN rail (detail A).

When doing this ensure that all featherkeys and keyways on adjacent terminals are securely interlocked.

The keyway/featherkey connection links adjacent terminals together and ensures that potential routing is created safely.

The keyways of an electronics base do not continue on the connector of terminals for the 24 V DC area. When snapping on a power housing, there must be no 24 V connector on the left-hand side of the housing. If a connector is present, it will have to be removed.

Figure 9-14 Mounting a power-level terminal

- Next, attach the required connectors to the housing. The available connections are described in Section "Connections on a power-level terminal (Inline Modular IO)" on page 139.

Removal

When removing a terminal, proceed as shown in Figure 9-15:

• If adjacent terminals belong to the 24 V DC or 120 V AC/230 V AC area: Remove the adjacent connectors of the neighboring terminals (Figure 9-12 on page 114). This prevents the potential routing knife contacts and the keyway/featherkey connection from being damaged.
• Lift the release flaps towards the center of the power-level terminal (Figure 9-15, detail A).
• Remove the power-level terminal by uniformly pulling the release flaps straight back from the DIN rail (detail B). If you have not removed the connector of the adjacent terminal on the left, remove it now in order to protect the potential routing featherkeys and the keyway/featherkey connection.

Before removing the base, disconnect all the necessary connectors, so as to provide access to the base latch.

When using extended double signal connectors (long connectors), please ensure that you do not bend them back too far, as you may break the front snap-on mechanism.

• Lift the connector that is to be removed by pressing on the back connector shaft latching (Figure 9-18, A).
• Remove the connector (B).
• Insert a tool in the base latch and pull gently upwards (Figure 9-19, A). Pull the module out from the DIN rail (B, C).

9.6.3 Order of the Inline Modular IO terminals

9.6.3.1 General order

The order of the terminals within an Inline station should depend on the current consumption of the I/O from the potential jumpers U_M and U_S .

As the voltage at every power terminal is reinjected into the potential jumpers U_M and U_S , the section (main circuit) between a bus coupler and a power terminal or between a power terminal and another power terminal must always be considered when calculating the current. If power terminals are not used, the entire station is a main circuit.

Within a main circuit, install the terminals according to their current consumption. Install the terminals with the highest current consumption first. This has the advantage that the high supply current does not flow through the entire main circuit and thus does not flow through all the terminals.

The following order is recommended.

Table 9-1 Order of the Inline terminals within a main circuit

	Function Abbreviation	in order designation	Function identi-fication	Note
1	Digital output DO, SDO	Pink, red,	dark red	In descending order of current consumption
2	Digital input DI, SDI Light	blue, blue,	dark blue	In descending order of current consumption
3	Relay DOR, SDOR Dark	red
4	Power ELR, MLR,	EC AR, DC AR	Dark red See also	9.6.3.4
5	Special functions		Orange	In descending order of current consumption
	- Open and closed-loop control	PWM, CNT, SSI, INC, TEMPCON
	- Communication	RS, ASI MA, DALI
	- Detection	INC-IN, SSI-IN, IMPULSE-IN
	- Safety	SAFE		Please observe any special requirements (subsequent safety-related segment circuit or subsequent power-level terminals).
6	Analog output	AO	Yellow	In descending order of current consumption; see also 9.6.3.3
7	Analog input	AI, SGI, TEMP	Green	In descending order of current consumption; see also 9.6.3.3
		IB IL TEMP 2/UTH-PAC		As the last terminal

Please also observe the following notes:

• In the event of any further restrictions regarding the position of a terminal, please refer to the terminal-specific data sheet.
• For the current consumption of the terminals, please refer to the relevant terminal-specific data sheet.

9.6.3.2 Remote bus branch in an Inline station

If you want to integrate a remote bus branch into an Inline station, please note that the terminal with remote bus branch must be placed directly after a bus terminal, an Inline Controller or another terminal with remote bus branch.

Please refer to the corresponding data sheets to see if any other special requirements should be observed.

9.6.3.3 Positioning terminals for analog signals

High current flowing through potential jumpers U_M and U_S leads to a temperature rise in the potential jumpers and inside the terminal. This reduces the measuring accuracy and shortens the service life of the terminal.

To keep the current flowing through the potential jumpers of the analog terminals as low as possible, always place the analog terminals after all the other terminals at the end of the main circuit.

Within the analog terminals, position the IB IL TEMP 2/UTH-PAC terminal after all the other terminals to keep the current flowing through all the potential jumpers for this terminal as low as possible.

9.6.3.4 Positioning power-level terminals

In a 24 V DC area, position the power-level terminals anywhere in the main circuit, but before the analog terminals.

In a 24 V DC area, power-level terminals can be positioned anywhere in the main circuit before terminals with a special function and analog terminals. Due to noise emissions, power-level terminals with mechanical load relay (MLR) should be positioned away from analog terminals, i.e., they must not be placed adjacent to them.

Please note that only adjacent power-level terminals can be connected for potential jumpering using power bridges.

9.6.3.5 Example of the structure of a main circuit

Table 9-2 Example: Structure of a main circuit

TerminalTypeReason for position
1 IB IL 24 DO 16-PAC	Digital output terminal	DO, current higher than for 2;please observe note below table
2 IB IL 24 DO 2-PAC Digital output terminal DO
3 IB IL 24 DI 16-PAC	Digital input terminal	DI, current higher than for 4
4 IB IL 24 DI 2-PAC Digital input terminal DI
5 IB IL 400 MLR 1-8A	Power-level terminal	Any, before analog
6 IB IL CNT-PAC Function terminal
7 IB IL AO 2/SF-PAC Analog output terminal AO
8 IB IL TEMP 2/UTH-PAC	Analog input terminal	AI, after all others

NOTE:

In the event of high simultaneity of digital outputs and maximum current load, insert a power terminal after the IB IL 24 DO 16-PAC terminal.

If the maximum load of the outputs is 0.2 A, an additional power terminal is not required. This configuration is in Figure 9-20.

Figure 9-20 Suggested solution

10 Connecting cables

10.1 Connecting cables using Inline connectors

Excluding a few exceptions, the cables for the I/O and supply voltages are connected via Inline connectors using the spring-cage method. This means that signals up to 250 V AC/DC and 8 A can be connected with a conductor cross-section of 0.08 mm^2 to 1.5 mm^2 .

Please observe the permissible lengths for sensor/actuator cables (see Section "Cable connection method/cross-section" on page 151 or terminal-specific data sheet).

Both shielded and unshielded cables are used with Inline Modular IO terminals or Inline Block IO modules.

10.1.1 Connecting unshielded cables

Figure 10-1 Connecting unshielded cables

Wire the connectors according to your application.

For the connector pin assignment, please refer to the corresponding terminal-specific data sheet.

When wiring, proceed as follows:

- Strip 8 mm off the cable.

Inline wiring is normally done without ferrules. However, it is possible to use ferrules. If using ferrules, make sure they are properly crimped.

• Push a screwdriver into the slot of the appropriate terminal point (Figure 10-1, detail 1), so that you can insert the wire into the spring opening.
  Phoenix Contact recommends using a SZF 1 - 0,6X3,5 screwdriver (Order No. 1204517).
• Insert the wire (Figure 10-1, detail 2). Remove the screwdriver from the opening. This clamps the wire.

Following installation, the wires and the terminal points should be labeled (see also Section "Function identification and labeling" on page 53).

10.1.2 Connecting shielded cables using an Inline shield connector

Shielded cables can be connected via IB IL SCN-6 SHIELD and

IB IL SCN 6-SHIELD-TWIN shield connectors. The IB IL SCN-6 SHIELD shield connector is designed to connect one shielded cable. Two shielded cables can be easily connected via the IB IL SCN 6-SHIELD-TWIN shield connector. In principle, cables are connected via the shield connector in the same way as shown in Figure 10-2 on page 125 and Figure 10-3 on page 126.

Figure 10-2 shows the connection of a shielded cable using a remote bus cable as an example. In this example, the cables are twisted pair cables.

Figure 10-3 shows the connection of two shielded cables, using the wiring of the IB IL AI 2/SF-PAC terminal as an example. As two channels can be used here, the IB IL SCN 6-SHIELD-TWIN shield connector is used.

When connecting the cables proceed as shown in Figure 10-2 and Figure 10-3:

Stripping cables

• Strip the outer cable sheath to the desired length (a) (detail A).
  The desired length (a) depends on the connection position of the wires and whether the wires should have a large or small amount of space between the connection point and the shield connection.
• Shorten the braided shield to 15 mm (detail A).
• Fold the braided shield back over the outer sheath (detail B).
• Remove the protective foil.
• Strip 8 mm off the wires (detail B).

Inline wiring is normally done without ferrules. However, it is possible to use ferrules. If using ferrules, make sure they are properly crimped.

When using twisted pair cables, keep the wire twisted until just before the terminal point.

Wiring the connectors

- Push a screwdriver into the actuation shaft of the appropriate terminal point (Figure 10-1 on page 123, detail 1), so that you can insert the wire into the spring opening.

Phoenix Contact recommends using a SZF 1 - 0,6X3,5 screwdriver (Order No. 1204517).

- Insert the wire (Figure 10-1 on page 123, detail 2). Remove the screwdriver from the opening. This clamps the wire.

For the connector pin assignment, please refer to the corresponding terminal-specific data sheet.

Connecting the shield

Figure 10-2 shows the shield connection for the IB IL SCN 6-SHIELD connector. The procedure for the IB IL SCN 6-SHIELD-TWIN connector (shown in Figure 10-3) is the same.

• Open the shield connection (detail C).
• Check the position of the shield connection clamp in the shield connection (see also "Shield connection clamp" on page 127).
• Place the cable with the folded braided shield in the shield connection (detail D).
• Close the shield connection (detail E).
• Tighten the screws on the shield connection with a screwdriver (detail F).

To ensure that the shield connection clamp remains in place when the shield connection is closed, first secure the shield clamp with screws and then close the shield connection.

Shield connection clamp

The shield connection clamp (a in Figure 10-4, detail B) in the shield connection can be used in various ways depending on the cable cross-section. For thicker cables (e.g., bus cable), the dip in the clamp must be turned away from the cable (Figure 10-4, detail B). For thinner cables, the dip in the clamp must be turned towards the cable (Figure 10-4, detail F).

If you need to change the position of the shield connection clamp, proceed as shown in Figure 10-4:

• Open the shield connection housing (detail A).
• The shield connection is delivered with the clamp positioned for connecting thicker cables (detail B).
• Remove the clamp (detail C), turn it to suit the cross-section of the cable (detail D), then reinsert the clamp (detail E).
  • Detail F shows the position of the clamp for a thin cable.

10.1.3 Connecting shielded cables using an Inline connector

With analog, function, or communication terminals without Inline shield plug, shielding can be connected by separate accessories. Connect the shielding with the shielding accessories given in the ordering data.

Please refer to the "Ordering data for accessories: shield connection" on page 153 for the recommended accessories. You will also find the relevant information in the terminal-specific data sheet.

10.2 Connecting the power supplies

Inline Modular IO

To operate an Inline station you must provide the supply voltage for the bus coupler, the logic of the terminals, and the sensors and actuators.

Connect the power supplies using unshielded cables as described in Section "Connecting unshielded cables" on page 123.

For the connector pin assignment of the supply voltage connections, please refer to the terminal-specific data sheets for bus couplers, power terminals, and segment terminals.

Inline Block IO

When using Inline Block IO modules, the supply voltage for the module and the sensors and actuators must be provided. Depending on the module, connection can be via Inline connector or COMBICON connector.

The power supplies are connected using unshielded cables. For connection via Inline connector, see Section “Connecting unshielded cables” on page 123.

For the connector pin assignments for connecting supply voltages, please refer to the relevant module-specific data sheet.

10.2.1 Inline Modular IO: Supply options

Bus coupler supply

For detailed information, please refer to the documentation for your bus coupler.

Power terminal supply

Depending on the type of power terminal, the following supply voltages can be supplied or provided:

• U_M and U_S (I/O supply voltage)
• U_24V (generation of U_L and U_ANA ), U_M , and U_S (communications power and I/O supply voltage)

Please also refer to the information provided in Section “Power, segment, and accessory terminals” on page 29.

Providing the segment voltage at segment terminals

At segment terminals, the segment voltage U_S is provided from the main circuit U_M .

Please also refer to the information provided in Section "Power, segment, and accessory terminals" on page 29.

Notes on supply voltages

The bus coupler supplies the module electronics of the connected terminals with communications power ( U_L ), which is generated, for example, from the bus coupler supply voltage ( U_BK ). If the supply voltage U_BK is disconnected, the bus stops.

The supply voltage to the sensors and actuators ( U_M/U_S ) should be installed and protected independently of the bus coupler supply ( U_BK ). In this way the bus continues to run even if some I/O devices are switched off.

10.2.2 Power supply requirements

WARNING: Dangerous contact voltage

Only use power supply units that ensure safe isolation between the primary and secondary circuits according to EN 50178.

For additional power supply requirements, please refer to the documentation for your bus coupler and the power terminals.

Inline Modular IO: Supply voltage requirements that differ from the system specifications

The specifications for Inline system supply voltages are described in “Technical data for Inline Modular IO” on page 147. However, some terminals have specific requirements. Therefore, always refer to the corresponding data sheet.

This section provides information about the various possible requirements within an Inline system.

Table 10-1 Supply voltage requirements of various products (example)

	Inline (system requirements)	IB IL 400 MLR 1-8A
Nominal voltage 24 V DC 24 V DC
Ripple ±5% ±5%
Permissible voltage range (including ripple)	19.2 V DC to 30.0 V DC	19.2 V DC to 28.8 V DC
Documented in “Technical data for Inline Modular IO” on page 147		Data sheet

If you are using Inline in a system with other product ranges, also observe the technical data for these product ranges. Please refer to the corresponding documentation for this technical data.

Two options are available when using terminals, which have special requirements regarding the power supply:

1 Observe the specific parameters for the power supply in the entire system.
2 Observe the specific parameters in the main circuit where the terminals are located.

10.3 Recommendation for supplying the supply voltage and resetting the voltage with regard to Inline Modular

10.3.1 Supply at the bus head

In the Inline terminals, electrical isolation is implemented between the logic and I/O devices. To prevent decreasing the electrical isolation, the voltages for supplying the logic and for supplying the I/O devices must be provided separately using two separate power supply units.

10.3.4 Testing the supply during startup

During startup, make sure that all GND connections of the supply connectors of an Inline station are connected to GND (0 V) of the relevant power supply unit by means of measurement. For this purpose, remove all power connectors from the relevant terminals and measure the connection.

When using power terminals, make sure that they are assigned to the correct power supply unit in order not to decrease electrical isolation within the station.

10.3.5 Behavior during reset at the bus coupler, Inline controller or field multiplexer

NOTE: Malfunction

If you want to perform a reset at the head of the Inline station by switching the supply voltage off and on again, disconnect power to all I/O devices connected.

Disregarding this measure may lead to unwanted feedback.

10.4 Connecting the bus

The bus cable for your system is connected directly to the module in the case of Inline Block IO and to a bus coupler in the case of Inline Modular IO. Table 10-4 below lists the basic options for connecting the bus.

10.5 Connecting sensors and actuators

Sensors and actuators are connected using connectors. The relevant terminal-specific data sheet indicates which connector(s) can be used for which terminal.

Connect the unshielded cables as described in Section “Connecting unshielded cables” on page 123.

Connect the shielded cables as described in Section “Connecting shielded cables using an Inline shield connector” on page 124.

10.5.1 Connection methods for sensors and actuators

Most of the digital I/O terminals in the Inline product range support the connection of sensors and actuators in 1, 2, 3 or 4-wire technology.

Because of the different types of connectors, a single connector can support the following connection methods:

• 8 sensors or actuators in 1-wire technology

10.5.3 The various connection methods for sensors and actuators

1-wire technology

Figure 10-8 1-wire termination for digital devices

Sensor

Figure 10-9, detail A, shows the detection of a sensor signal schematically. The SW switch provides the input signal. The sensor signal is led to terminal point IN1. The sensor is supplied by the voltage U_S .

NOTE: Malfunction due to potential shifts

Supply the sensors and U_S of the Inline station from the same power supply. Make sure that there is at least one common GND as reference potential.

This will prevent potential shifts, which can have undesirable effects on the function of the station.

Actuator

Figure 10-9, detail B, shows the connection of an actuator. The actuator is supplied by output OUT1. The load is switched directly via the output.

NOTE: Malfunction due to potential shifts

Make sure that GND of the actuators and GND of the supply voltage U_S , which supply the actuators, have the same potential.

This will prevent potential shifts, which can have undesirable effects on the function of the station.

At the time of going to print, the IB IL 24 DI 32-PAC and IB IL 24 DO 32-PAC Inline terminals are designed to connect sensors and actuators in 1-wire technology. For connection examples, please refer to the corresponding data sheets.

2-wire technology

10.6.3 Connecting the brake module and brake (optional)

The brake module can be used to control the brake on motors with a brake. It contains a passive semiconductor, which can be used for quick motor braking. The brake module is designed for motors with a nominal voltage of 400 V AC.

Assemble the connector for the brake as shown in Figure 10-21:

• Strip approximately 30 mm off the outer cable sheath (detail A).
• Strip approximately 7 mm off the wires (detail B).
  • Fit the wire ends with ferrules and connect the wires to the connector (detail C).

Make sure that the brake is connected with the correct polarity, otherwise it may not operate correctly.

Figure 10-21 Assembling the connector for the brake

The brake module is snapped into connection X8 of a power-level terminal using a 3-pos. inverted COMBICON connector. The 2-pos. COMBICON connector for the brake is snapped into connection X9 of the brake module.

Connect the brake as shown in Figure 10-22:

• If the motor connector is plugged in, remove it. The entire module should be prepared (power-level terminal with brake module) before the I/O is connected.
• Lift up the lower release flap (detail A1).
• Snap the brake module into connection X8 (detail A2). Fasten the brake module by turning the interlocking screw (1) 90°. This secures the interlocking screw in a ventilation slot of the power-level terminal.
• Put the lower release flap down again (detail B1).
• Insert the assembled motor circuit connector into connection X10 (detail B2). (See also Section "Connecting the motor circuit connector" on page 142.)
• Insert the assembled connector for the brake into connection X9 of the brake module (detail B3).

Figure 10-22 Snapping on the brake module and the connector for the brake

For additional information about the brake module, please refer to the module-specific data sheet.

10.6.4 Connecting the hand-held operator panel

Hand-held operator panel mode (manual mode) is enabled via a temporarily connected external hand-held operator panel. This panel is connected to the power-level terminal using a 4-pos. MINI-COMBICON connector. The slot is under the upper release flap (6 in Figure 10-12 on page 139). The hand-held operator panel can only be connected when the release flap is upright.

For the ordering data for the hand-held operator panel, please refer to the Phoenix Contact catalog.

For additional information about hand-held operator panel mode, please refer to the data sheets for the power-level terminals.

10.6.5 Enabling the power level/24 V isolation

The MINI-COMBICON connector for terminal strip X18 (enable power level/24 V isolation) is under the upper release flap of a power-level terminal.

Figure 10-23 Assignment of the enable power level/24 V isolation connection

Table 10-9 Enable power level X18 (MINI-COMBICON)

Pin X18 (enable)

1 1 (24 V DC segment voltage US)

2 2 (enable power level)

The control voltage for the power level and the brake is supplied via pin 2 of the MINICOMBICON connector. The power level cannot be controlled without the 24 V control voltage.

The segment voltage U_S is used to enable the power level and can be made available using a jumper or a switch:

1 By default upon delivery, terminal strip X18 is supplied with a jumper inserted between pins 1 and 2.
If no switch is connected to X18, the jumper can remain inserted. The power level of the power-level terminal is enabled because the 24 V segment voltage is directly available.
2 If an external switch is connected between pins 1 and 2 on terminal strip X18, the power level of the power-level terminal is enabled when the switch is closed.

For additional information and safety notes, please refer to the data sheets for the power-level terminals.

In these cases, consider the individual terminal or application separately.

The Inline terminals are approved for use up to an elevation of 3000 m above sea level, see “Technical data for Inline Modular IO” on page 147.

The maximum permissible ambient temperature decreases at elevations above this level. Therefore, keep temperature derating in mind when using the terminals at an elevation greater than 3000 m up to 5000 m.

A 5 Temperature response of the terminals

	Please note that derating or simultaneity limitations must be taken into consideration depending on the ambient temperature. Notes on this are provided in the terminal-specific data sheets. The terms used in the data sheets are explained below:
Power dissipation of the electronics ( P_TOT )	The power dissipation of the electronics of a terminal is calculated according to the formula provided in the terminal-specific data sheet. The calculated value must not exceed the power dissipation of the housing.
Power dissipation of the housing ( P_HOU )	The power dissipation of the housing indicates the maximum power dissipation. The maximum power dissipation is specified in the terminal-specific data sheet.In the permissible operating temperature range, the power dissipation of the housing can be dependent on or independent of the ambient temperature.If the power dissipation of the housing depends on the ambient temperature, a permissible working point must be defined.
Permissible working point	Depending on the power dissipation of the housing and the power dissipation of the electronics at a certain current, the maximum temperature at which the terminal can be operated with this current can be calculated.
Examples	Examples for calculating these values can be found in the section below.

A 6 Calculation examples for power dissipation and working points

A 6.1 Constant power dissipation of the housing over the operating temperature range

This calculation is illustrated using the IB IL 24 DO 8-PAC terminal as an example.

Formula to calculate the power dissipation of the electronics

This formula is terminal-specific and is provided in every data sheet.

$$ P _ {T O T} = 0. 1 9 \mathrm{W} + \sum_ {\mathrm{i} = 1} ^ {\mathrm{n}} (0. 1 0 \mathrm{W} + \mathrm{I} _ {\mathrm{Li}} ^ {2} \times 0. 4 0 \Omega) $$

Where

P_TOT Total power dissipation of the electronics

i l n d e x

n Number of set outputs (n = 1 to 8)

I_Li Load current of output i

If no output is set, the component with the sigma sign is omitted.

Example: Load currents of the outputs:

$$ I _ {L 1} = 0. 5 \mathrm{A}, I _ {L 2} = 0. 4 \mathrm{A}, I _ {L 3} = 0. 2 \mathrm{A}, I _ {L 4} = 0. 5 \mathrm{A}, I _ {L 5} = 0. 3 \mathrm{A}, I _ {L 6} = 0. 4 \mathrm{A} $$

Outputs 7 and 8 are not used.

Power dissipation of the electronics According to the formula, the electronics of this specific configuration has the following power dissipation:

$$ P _ {T O T} = 0. 1 9 \mathrm{W} + [ 0. 1 \mathrm{W} + (0. 5 \mathrm{A}) ^ {2} \times 0. 4 \Omega ] $$

$$ + [ 0. 1 \mathrm{W} + (0. 4 \mathrm{A}) ^ {2} \times 0. 4 \Omega ] $$

$$ + [ 0. 1 \mathrm{W} + (0. 2 \mathrm{A}) ^ {2} \times 0. 4 \Omega ] $$

$$ + [ 0. 1 \mathrm{W} + (0. 5 \mathrm{A}) ^ {2} \times 0. 4 \Omega ] $$

$$ + [ 0. 1 \mathrm{W} + (0. 3 \mathrm{A}) ^ {2} \times 0. 4 \Omega ] $$

$$ + [ 0. 1 \mathrm{W} + (0. 4 \mathrm{A}) ^ {2} \times 0. 4 \Omega ] $$

$$ P _ {T O T} = 0. 1 9 \mathrm{W} + 0. 2 0 0 \mathrm{W} + 0. 1 6 4 \mathrm{W} + 0. 1 1 6 \mathrm{W} $$

$$ + 0. 2 0 0 \mathrm{W} + 0. 1 3 6 \mathrm{W} + 0. 1 6 4 \mathrm{W} $$

$$ P _ {T O T} = 1. 3 7 \mathrm{W} $$

Power dissipation of the housing	The value for the power dissipation of the housing is specified in every terminal-specific data sheet.The power dissipation of the housing for the specified terminal is 2.7 W within the operating temperature range of -25°C to +55°C. The calculated power dissipation for the electronics therefore does not exceed the permissible upper limit.
Maximum load	Even with the maximum permissible load current (0.5 A per channel), the upper limit of 2.7 W is not exceeded within the permissible temperature range of -25°C to +55°C. P_TOT = 0.19 W + 8 × [0.1 W + (0.5 A)^2 × 0.4 ] P_TOT = 1.79 W

A 6.2 Power dissipation of the housing within the operating temperature range depending on the ambient temperature

This calculation is illustrated using the IB IL 24 DO 2-2A-PAC terminal as an example.

Formula to calculate the power dissipation of the electronics

This formula is terminal-specific and is provided in every data sheet.

$$ P _ {T O T} = 0. 1 8 \mathrm{W} + \sum_ {\mathrm{i} = 1} ^ {\mathrm{n}} (0. 2 0 \mathrm{W} + \mathrm{I} _ {\mathrm{Li}} ^ {2} \times 0. 1 0 \Omega) $$

Where

P_TOT Total power dissipation of the electronics

i l n d e x

n Number of set outputs (n = 1 to 2)

I_Li Load current of output i

If no output is set, the component with the sigma sign is omitted.

Example:

Both outputs are enabled and operating at full load. The load currents of the outputs are I_L1 = I_L2 = 2 A .

Power dissipation of the electronics

According to the formula, the electronics of this specific configuration has the following power dissipation:

$$ P _ {T O T} = 0. 1 8 \mathrm{W} + 2 \times [ 0. 2 0 \mathrm{W} + (2 \mathrm{A}) ^ {2} \times 0. 1 0 \Omega ] $$

$$ P _ {T O T} = 0. 1 8 \mathrm{W} + 2 \times 0. 6 \mathrm{W} $$

$$ P _ {T O T} = 0. 1 8 \mathrm{W} + 1. 2 0 \mathrm{W} $$

$$ P _ {T O T} = 1. 3 8 \mathrm{W} $$

Power dissipation of the housing

The value for the power dissipation of the housing is specified in every terminal-specific data sheet.

The permissible power dissipation of the housing for the IB IL 24 DO 2-2A-PAC terminal depends on the temperature.

$$ P _ {H O U} = 2. 4 \mathrm{W} - 2 5 ^ {\circ} \mathrm{C} < T \quad A \leq - 5 ^ {\circ} \mathrm{C} $$

$$ P _ {H O U} = 2. 4 \mathrm{W} - \left[ \left(T _ {\mathrm{A}} - (- 5 ^ {\circ} \mathrm{C})\right) / 3 7. 5 ^ {\circ} \mathrm{C} / \mathrm{W} \right] - 5 ^ {\circ} \mathrm{C} < T \quad A \leq + 5 5 ^ {\circ} \mathrm{C} $$

Where

P_HOU Power dissipation of the housing

T_A Ambient temperature

At an ambient temperature of up to -5^ , you can load the housing with the maximum power dissipation.

Permissible working point

At an increased ambient temperature, you must calculate the permissible working point for the calculated power dissipation.

To do this set P_TOT = P_HOU .

$$ P _ {T O T} = 2. 4 \mathrm{W} - \left[ \left(T _ {\mathrm{A}} + 5 ^ {\circ} \mathrm{C}\right) / 3 7. 5 ^ {\circ} \mathrm{C} / \mathrm{W} \right] $$

After changing the formula, the maximum permissible ambient temperature, with this load, is calculated as:

$$ T _ {A} = (2. 4 \mathrm{W} - P _ {\text { T O T }}) \times 3 7. 5 ^ {\circ} \mathrm{C} / \mathrm{W} - 5 ^ {\circ} \mathrm{C} $$

P_TOT = 1.38 W (from the calculation for the power dissipation of the electronics)

$$ T _ {A} = (2. 4 \mathrm{W} - 1. 3 8 \mathrm{W}) \times 3 7. 5 ^ {\circ} \mathrm{C} / \mathrm{W} - 5 ^ {\circ} \mathrm{C} $$

$$ T _ {A} = 1. 0 2 \mathrm{W} \times 3 7. 5 ^ {\circ} \mathrm{C} / \mathrm{W} - 5 ^ {\circ} \mathrm{C} $$

$$ T _ {A} = 3 3. 2 5 ^ {\circ} C $$

With both outputs at full load, this terminal can be operated up to an ambient temperature of 33^ C.

If you never operate the outputs simultaneously and if a set output consumes a current of 2 A, you can operate up to an ambient temperature of:

$$ P _ {T O T} = 0. 1 8 \mathrm{W} + [ 0. 2 0 \mathrm{W} + (2 \mathrm{A}) ^ {2} \times 0. 1 0 \Omega ] $$

$$ P _ {T O T} = 0. 1 8 \mathrm{W} + 0. 6 0 \mathrm{W} $$

$$ P _ {T O T} = 0. 7 8 \mathrm{W} $$

$$ T _ {A} = (2. 4 W - P _ {T O T}) \times 3 7. 5 ^ {\circ} C / W - 5 ^ {\circ} C $$

P_TOT = 0.78 W (from the calculation for the power dissipation of the electronics)

$$ T _ {A} = (2. 4 \mathrm{W} - 0. 7 8 \mathrm{W}) \times 3 7. 5 ^ {\circ} \mathrm{C} / \mathrm{W} - 5 ^ {\circ} \mathrm{C} $$

$$ T _ {A} = 1. 6 2 W \times 3 7. 5 ^ {\circ} C / W - 5 ^ {\circ} C $$

$$ T _ {A} = 5 5. 7 5 ^ {\circ} C $$

T_A=55^ (maximum permissible ambient temperature)

As the maximum permissible ambient temperature is 55^ C, you can operate under the conditions specified above in the entire permissible temperature range. This results in a simultaneity of 50% at 55^ C as specified in the data sheet.

This ground is free from external noise voltage, and is used to ground cable shields and to suppress noise and interference voltages.

Functional earth ground is a low-impedance current path between circuits and ground. It is not designed as a safety measure but rather, for example, for the improvement of noise immunity (EN 61131).

This ground connection must be separated from parts with hazardous voltage by means of double or reinforced insulation (EN 60950).

PE Protective earth ground

This ground is used to ground devices. It also provides shock protection for people.

Protective earth ground is a low-impedance current path that minimizes the risk to the user in the event of an error (EN 61131).

GND 0 V ground; housing or chassis

In this user manual the term ground refers to common voltage return lines. Ground is electrically isolated from FE and PE. If a jumper is placed between ground and FE or PE, this isolation is removed.
