Pin assignment of plug connectors

Pin assignment of I/O connections
Prior to commissioning, the pluggable terminal blocks (Fig.
5) included in the scope of
delivery for the IN and OUT connections must be connected to the communication lines of
the control / sensor system provided by the customer in deenergised condition. The inputs
must be pulled to GND via switching contacts. The outputs are designed as pull-up resistor
(inversion at the output).
The following table shall apply to pin assignment.
