2 Safety instructions

- The unit described is a subcomponent for integration into a system.

• The system architect is responsible for the safety of the system.

• The system architect undertakes to perform a risk assessment and to create documentation in accordance with legal and normative requirements to be provided to the operator and user of the system. This documentation must contain all necessary information and safety instructions for the operator, the user and, if applicable, for any service personnel authorised by the architect of the system.

• Read this document before setting up the product and keep it during the entire service life.

• The product must be suitable for the corresponding applications and environmental conditions without any restrictions.
• Only use the product for its intended purpose (→ Intended use).
• If the operating instructions or the technical data are not adhered to, personal injury and/or damage to property may occur.
• The manufacturer assumes no liability or warranty for any consequences caused by tampering with the product or incorrect use by the operator.
• Installation, electrical connection, set-up, operation and maintenance of the product must be carried out by qualified personnel authorised by the machine operator.
• Protect units and cables against damage.
• Replace damaged units, otherwise the technical data and safety will be impaired.
• Observe applicable documents.

3 Intended use

The device is used for the electrically isolated switching of signals or currents. Control is via the 24 V digital inputs (IEC 61131 Type 3). The device has 2 outputs configured as normally open (opto semiconductor relay). A separate voltage supply must be provided at the output side. DC and AC voltages can be switched.

The device is suitable for wet environments. Observe the instructions in the chapters “Installation” and “Electrical connection”.

4 Installation

ATTENTION

Higher shock > IK06

▷ Damage possible
▷ Protection rating and, in wet environments, electrical protection might be impaired
▶ If necessary, the system creator must take external measures to protect the device depending on the requirements of the corresponding application.
▶ Replace damaged devices, otherwise the technical data and safety will be impaired.

The IP rating of the overall system depends on the protection ratings of the individual devices, the applied connection elements and the corresponding protective caps.

ATTENTION

No protection rating / no protection of the contacts without mounted connectors / protective caps.

▷ Inadmissible soiling / moisture possible.
▷ Disconnection of circuits / safety possibly impaired.
▷ Before installation / when replacing the device, maintain pollution degree 2.
▶ Disconnection / safety guaranteed.

▶ Install the device so that the M12 connection parts and the device are protected from mechanical stress such as shock and vibration.
▶ If necessary, fix the device with a mounting clip. Use M4 screw or cable tie for this purpose.

The mounting clip is not supplied with the device. More information about available accessories at www.ifm.com.

5 Electrical connection

The unit must be connected by a qualified electrician.

▶ Observe the national and international regulations for the installation of electrical equipment.

CAUTION

Use in wet environments

▷ Electric shock possible.
▶ Voltage derating required ( → Technical data).

The input and output circuits are insulated from each other and from device surfaces that could be touched with basic insulation according to IEC 61010-1 (secondary circuit with max. 32 V DC, supplied from the mains circuit up to 300 V of overvoltage category II).

The external wiring has to be carried out in a way that ensures the required separation from other circuits.

5.1 Input side

Operating voltage (SELV/PELV)

CAUTION

The input current of the operating voltage is not limited.

▷ No fire protection.
▶ Protect the circuit.
▶ Protect the sensor supply via the same fuse.

Potential	M12 connector 1	Fuse
L+ / supply voltage	Pin 1	≤ 2 A

Required tripping characteristic of the fuse:

T_fuse ≤ 120 s at max. 6.25 A (fire protection)

5.2 Output side

Supply voltage output: as specified in the technical data (SELV / PELV)

CAUTION

Solid-state switches are sensitive to overvoltage.

▷ Defect due to overvoltage possible.
▶ Protect solid-state switches externally against overvoltage ( → Technical data).
▶ External interference suppression of inductive loads is required (free wheel diode).

CAUTION

The output current is not limited.

▷ No fire protection.
▷ Risk of defect due to overload / short circuit.
▶ Limit the output current.

▶ Protect the circuit.

Potential	M12 socket 2	Fuse
OUT1	Pin 2	≤ 1.25 A fast acting
OUT2	Pin 4	≤ 1.25 A fast acting
L1/L+ (alternative to individual protection of the outputs)	Pin 1	≤ 1.25 A fast acting(total current with common protection: 1 A)

Capacitive loads are not permitted (opto semiconductor relay).

Max. switching frequency of the outputs: 1 Hz

5.3.1 Mounting the connector

The threaded connections in the device correspond to the M12 standard. To ensure compliance with the specified protection rating, only cables that comply with this standard may be used. In the case of self-assembled cables, the system manufacturer is responsible for the protection rating.

▶ Use connectors with gold-plated contacts.
▶ During installation, place the connectors vertically so that the coupling nut will not damage the thread.
▶ Observe the coding of the connectors during installation.

If connector in the device:

▶ Tighten the cable sockets according to the torque specifications indicated by the cable vendor. Maximum permissible tightening torque: 1.8 Nm

If sockets in the device:

▶ Tighten the cable plug using 1.3 ± 0.1 Nm.
▶ Provide all outgoing cables with suitable strain relief after a maximum of 200 mm. Observe the minimum bending radius of the cables ( → information from the cable manufacturer).

! Maximum cable length: 30 m on each side

5.3.2 Removing the connector with vibration protection

▶ Press the connector against the unit and simultaneously loosen the coupling nut.

6 Operation

After power on, the device is ready for operation. It switches the outputs according to the incoming input signals.

7 Troubleshooting

Error	Root issue	Troubleshooting
The output does not switch	Supply voltage too low at the input side	Apply correct supply voltage at the input side
	No input signal	Apply the input signal
