Installation topology (PSC 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 PSC hybrid installation typology with an SEW-EURODRIVE hybrid cable for line voltage, STO signal, and communication. An optional 24 V backup voltage is led separately to the unit.

Decentralized drive units or decentralized inverters in communication design DFC or DSI with connection via mini I/O plug connector.

PSC hybrid cable for line voltage, STO signal, Ethernet fieldbus. Only 2-pole STO connection (2-pole sourcing/sinking, 2-channel serial sourcing, or 1-pole sourcing) permitted, see chapter "Functional safety". Max. permitted cable length between safety relay and the last inverter: 100 m.

The decentralized inverter is equipped with an integrated DC 24 V supply. Optionally, the inverter can be backed up with DC 24 V.
