3 Functions and features

The device transmits the input states of the digital type 2 inputs and the status of the sensor supply to IO-Link.

4 Function

4.1 Communication, parameter setting, evaluation

4.1.1 IO-Link data

The device

• transmits the current states of the digital inputs cyclically in byte 0. Byte 1 is not used and always transfers the value '0'.
• transmits the device information "short circuit" (SC) cyclically in byte 2.
• transmits the equipment identification cyclically in byte 3.
• provides the equipment identification for writing acyclically (index 688, sub-index 0).

4.1.2 Visual indication

The device

• indicates the current state of an input (yellow LED).
• indicates a correct operation (green PWR/FLT LED lights).
• indicates a short circuit of one or several sensor supplies (red PWR/FLT LED lights).

4.1.3 Parameter setting

Device-specific parameter lists for IO-Link parameter setting are available

www.ifm.com

4.2 Digital inputs

Depending on the version the device has 4 (AL2410) or 8 (AL2411) digital inputs (type 2 input to IEC 61131-2). All inputs refer to the sensor supply potential.

4.3 Sensor supply

Depending on the version the device has 4 (AL2410) or 8 (AL2411) process connections on the front panel. Each process connection has a sensor supply rated for a nominal current of 100mA .

The short-circuit protection applies to a group of 4 inputs

• group 1: inputs X1.0...X1.3
• group 2: inputs X1.4 - X1.7 (only AL2411)

and is rated for 400mA per group.

So the total current of the group of 4 inputs can be taken from one of the process connections of the corresponding group.

Maximum cable length < 30 m .

A short circuit or overload has no effect on the sensor supply of the other group (only AL2411). Moreover every sensor supply has a short-circuit and overload

detection which is indicated by the red PWR/FLT LED and via the IO-Link interface.

A correct operation is indicated by the green PWR/FLT LED. The output voltage of the sensor supply is in linear proportion to the input voltage (positive supply cable of the IO-Link port). Voltage can vary within the IO-Link specification (18...30 V).

5 Installation

Disconnect power before installation.

For installation choose a flat mounting surface. The entire bottom of the module must lie flat on the mounting surface.

• Fasten the module onto the mounting surface using M4 screws and washers (1). Tightening torque 1.2...1.5 Nm. Connect the plugs of the sensors to the M8 sockets.

• Tighten firmly, recommended tightening torque 0.3...0.5 Nm.

As an alternative the module can be mounted laterally using two M4 screws, tightening torque max. 1 Nm.

To ensure the protection rating

• Cover the unused sockets with the enclosed protective caps. Tighten firmly, recommended tightening torque 0.3...0.5 Nm.

UK

1: M4 screws and washers (not supplied with the device). Tightening torque 1.2...1.5 Nm.
2: M8 connector
3: M12 connector IO-Link (X1)

Observe the maximum tightening torque of the connection cable.

6 Electrical connection

The unit must be connected by a qualified electrician.

The national and international regulations for the installation of electrical equipment must be adhered to.

Intended for connection to class 2 (cULus class 2) circuits only.

Disconnect power.

Connect M12 plug (IO-Link) to the M12 socket. Tightening torque 0.6...0.8Nm.
Connect the device.

6.1 IO-Link connection

The IO-Link port must be connected according to the IO-Link specification.

The current required by the devices depends on the current load of the sensor supplies.

The total current (AL2410 = 550 mA and AL2411 = 1050 mA) must be provided by the connected IO-Link master.

If the positive supply cable is interrupted the device may be supplied via the IO-Link cable. This may lead to an unwanted system behaviour.

7 Pin connection

Inputs

1: Sensor supply +
3: Sensor supply -
4: Data input

1: L+
2: not connected
3:L-
4: C/Q / I/O-Link

8 Operating and display elements

UK

Green LED PWR / FLT on: everything ok

Red LED PWR / FLT on: short circuit on one or several sensor supplies

LED PWR / FLT off: undervoltage or disconnected system

Yellow LED IN input on: input provides a type 2 HIGH signal

Yellow LED IN input off: input provides a type 2 LOW signal

9 Maintenance, repair and disposal

The operation of the unit is maintenance-free.

After use dispose of the unit in an environmentally friendly way in accordance with the applicable national regulations.
