12v Trigger Relay Wiring

All About Wiring Diagram Information

12v Trigger Relay Wiring. Both motor legs rest at ground at the relays. Correct me if Im wrong but Im assuming that if I send 5v 2a to the trigger pin it will fry it.

Figure 2B - Opto-Isolated Relay Based 12V Trigger Circuit To obtain full galvanic isolation of the 12V trigger signal the circuit shown above should be used. This is practically identical to the 5 wire alternating 12V system. I have the relay in the picture above and have it powered with 5 volts.

I know that 4 of the 14 pins will be used on the relay.

Both motor legs rest at ground at the relays. Both motor legs rest at ground at the relays. I assume the 12v trigger is a mono RCA but again not sure. The only difference is theres no switch.
