The SmartWire-DT power module EU5C-SWD-PF2 loops the 24 V DC contac-
tor voltage and the 15 V module supply back into the SmartWire-DT cable.
The SmartWire-DT cable is looped from the SmartWire-DT in-connection
through to the SmartWire-DT out-connection. Only the 24 V DC contactor
voltage and the 15 V DC module supply are isolated and looped back in via
the SmartWire-DT out-connection.
The 24 V DC contactor supply is not electrically isolated from the 24 V DC
supply of the power module, i.e. the 24 V DC voltage is looped back in. There
is voltage reversal and EMC protection. Voltage dips are not buffered.
The 15 V DC module supply is electrically isolated from the 24 V DC contac-
tor voltage. Voltage dips are buffered up to at least 10 ms. There is voltage
reversal and EMC protection.
The subassembly contains an LED for indication of the 15 V DC slave supply.
The 24 V DC contactor voltage that is looped back in is not electrically iso-
lated from the 24 V DC supply voltage (AUX) of the module. There is voltage
reversal and EMC protection.
