I am using a DIGI wireless modem for communication between GE Fanuc MircoPLC's. The modem gets digital data over Modbus RS485 and DC voltage for power.
The supplier provided Belden 4 pair cables for the Modbus data transmission and an AC-DC adapter for the DC voltage.
So now, we have to lay two cables. One is the Belden for the Modbus and the other is 220Vac power which is converted to DC by the adapter at the modem JB.
I was wondering if it is acceptable to just send the DC over the Belden cable instead of laying two cables?
