relay wire diagram

please ignore the rectangle that's overlapping everything (unknown software problem)

 

diagram shows wiring for full relay set up with:-

5v dc power supply for relay coil's power.

24v dc power supply for electromagnets.

Arduino (actual unit to be used - mega) with 12 outputs.

resistors = 220r

diodes = 1N4001a

transistors = bc183

electromagnets = GMHX 030 (?) 24v dc
