12v Relay Wiring Diagram 5 Pin

By | April 7, 2023



Understanding how to properly wire a 12v relay 5 pin can be a bit intimidating for anyone unfamiliar with electrical components and circuits. This guide is designed to walk you through the process step by step, making wiring and troubleshooting a breeze.

First, familiarize yourself with the parts of the relay. The five pins are numbered from left to right, with the top pin being the common terminal (C). The next four pins are the normally open (NO), normally closed (NC) ,input(IN) and output (OUT) terminals. The two middle pins are the NO and NC switches, which control whether the circuit is open or closed.

Next, connect the power supply to the C and IN terminals. Make sure the voltage is appropriate; a 12V relay will only work with a 12V power source. If a higher voltage is used, the relay could be damaged. The power source should be connected to the relay before connecting any other components.

Finally, connect the load to the OUT and NO pins. Make sure that the load can safely handle the current supplied by the power supply. If necessary, use an in-line fuse to ensure the load isn’t damaged. Once all connections are made, the relay should activate when the power source is activated.

If it does not, then the connections should be double checked to make sure all the wires are firmly connected to the correct pins. If you still have trouble, you may need to replace the relay. Wiring a 12v relay 5 pin is a relatively simple task, but it is important to take the time to do it correctly. Taking the time to understand each component and how they work together will save you from costly repairs down the line.
