I need to supply 240VAC to a set of lights in the field. I also need to control the lights within a control room by the use of a PLC. Is it possible to feed a 240V supply to a box containing some contactors and a couple of relays. The contactors having the 240V supply and subsequently feeding the lights. Can a PLC 24VDC supply be used to energise the controlling relays within that panel?. would this cause any problems?
thanks
