Maximum input values.
3)
Maximum output values. The following figures show how the outputs are used.

Supported relay modes: "Normally Energized" (default), "Normally De-Energized". For configuration, see
section Configuration (Page 116).
5)
Certified PROFIBUS wiring recommended, see section PROFIBUS DP interface (Page 129)
6)
We recommend not to connect the connection cable directly to Ethernet connectors. Instead the sensor
connection cable kit should be used for this purpose.
