Good afternoon all,
I have an AB SLC 5/03 which uses multiple AC i/o cards (such as 1746-IA16 and 1746-OA16). I am using a 7-slot chassis with the first being processor, and next 4 being i/o cards. I am looking to install a 1746-IB16 (DC input card).
Question: Does the 24V supply for the input card have to come from the same 120V power supply that powers the rest of the PLC or is it acceptable to grab 24V from a different 120V power supply that does not touch the PLC at all?
Thanks,
