What is the wiring method of a five-pin relay?
1 Answers
Five-pin relay wiring method: A five-pin relay has two coils, one common terminal for contacts, one normally open contact, and one normally closed contact. The coils are connected to the control voltage. When energized, the relay will pull in, the normally open contact will close, and the normally closed contact will open. The five pins are labeled A, B, 1, 2, and 3. When A and B are not energized, 1 and 2 are connected. When AB is energized, 1 and 3 are connected. Automotive relays consist of a magnetic circuit system, contact system, and reset mechanism. The magnetic circuit system is composed of components such as the iron core, yoke, armature, and coil. The contact system consists of static reeds, moving reeds, and contact bases. The reset mechanism is made up of reset reeds or tension springs.
