Installation
Supply voltage
Profibus modules require a DC voltage of 24 V DC (SELF/PELF) for power.
The power can be provided by regulated and unregulated power supplies.
Regulated power supplies allow the output voltage to be increased above the nominal
voltage to compensate for line losses.
Note!
The use of a Profibus hybrid cable is not allowed.

Provide sensor/bus power and actuator power from separate power sources if
possible.
Note, Tip!
Module and connected sensors are supplied by the sensor supply. The output
stages are supplied by the actuator supply, except pin 4 of the IO-Link output
stage. These are supplied by the sensor supply.
Note, Tip!
Use different power sources for the sensor/bus and actuator if possible.
