I am building a relay circuit to control 12 solenoid valves (or other non-inductors). I've placed flyback diodes across each solenoid valve output (power & ground). Please see the attached picture.
This PCB will be put inside a box and connected via a cable to another box which contains all my solenoid valves. Since there are 12 valves, I do not really want to have 12 ground wires in my cable.
I plan to just take ground from 2 of the terminal block outputs. I just want to double check that doing this won't affect the flyback diode protection for the other valves. Since the grounds are all common, I don't expect any detrimental effects...but I just want to be sure. Is what I plan to do alright?
Thanks!
