Hi,
I need help to figure how to trigger 3 or 4 24vdc relays at 700m distance. Probably is too easy but... I have a 24vdc 1A power supply and 3 switches. Each switch should trigger a 24v relay but they are at near 700m distance. I'm unsure what cable to use (number of cores and sectional area)... This cable will run in cable trays with other cables. Can someone help me please?
Ty in advance!
