Installation topology (PAC hybrid installation example)

In this installation topology, fieldbus connection is made via mini I/O plug connector X42 and X43 at the connection unit. Use only electronics cover with the following connection configurations:

  • DFC.1.. / DSI.1.. (M12 plug connector for digital inputs/outputs)
  • DFC.2.. / DSI.2.. (Without M12 plug connector)

The following figure shows the basic PAC hybrid installation typology with a hybrid cable for line voltage, 24 V backup voltage, and communication. An optional STO signal is led separately to the unit.
