The CM IO-Link communication module enables data exchange with up to 4 IO-Link devices.
IO-Link devices (e.g. sensors) with a Class A port are connected using a 3-wire cable. IO-Link devices that require additional supply voltage and have a Class B port (e.g. actuators) are connected using a 5-wire cable.

Thanks to the compatibility of IO-Link with standard sensors, commercially available sensors in accordance with IEC 61131 Type 1 can also be operated on the IO-Link master.

The 30 mm wide I/O modules are especially suitable for use in extremely confined spaces, have settable parameters and diagnostic functions and can thus be adapted flexibly to the respective process requirements.

The following IO-Link masters are available:

• Communication module CM 4xIO-Link, 4xM12
