2023年10月16日 · Quick Summary: To wire a 12V relay, connect the 12V power source to Pin 30, the trigger control circuit to pins 85 and 86, the load to Pin 87, and, optionally, an alternative load to Pin 87a. I’ve included a couple of samples of how a 12V relay would be used together with circuit diagrams.

In this post, we will have a detailed look at the 12 Volt Relay. The electrical relay is a heavy-duty remote control switch that has features to handle high-current devices. Relays connected between power supply and electrical devices need power for on and off.
