POW/AUX (power supply for SmartWire-DT)
The POW/AUX interface is
not
galvanically isolated.
The following power supplies are required for a SmartWire-DT network:
Supply voltage POW:
The device supply voltage for the electronics of the downstream SmartWire-DT slaves (15 VDC)
is generated from the 24 V DC supply voltage applied to the POW connection.
Supply voltage AUX:
If there are any contactors or motor starters in the SmartWire-DT topology, a 24 V DC voltage AUX
must be additionally supplied as a control voltage for the contactor coils.
Additional properties of the required power supply, see chapter 9.5.2 SmartWire-DT Master,
Wiring
WAGO plug connector, Art no. 734-104 is supplied with the device.
