Hello all,
I'm trying to finish up a project left for our technology department. We have a project that requires 4 relays that are rated for 12vdc at 158 mA and my power supply is 12vdc at 2A. The wire used is copper 24 AWG and is 4 strands, but we only use 2 out of the 4.
The length of the wire (from power supply to relay) goes about 450-650 feet. I measured the voltage at each relay and the closet one gets about 12vdc while the furthest gets 10.6vdc.
Can anyone help? I'm not an electrician and this project was put in my lap. Should I look for a relay that requires less power (I tried calling and finding some) or should I just try and find a power supply that is a little larger? Any help is appreciated.
Thanks,
