What is pin 87A for?(relay) Ignition and Electrical ... Ok I think I may have answered my own question... After staring at some more diagrams, I think that the reason there are two 87 pins(87 & 87A) is because 87 is set up for a circuit that is normally open(the contact rest on 87A) and 87A is set up for a circuit that is normally closed and when the cicuit relay is energized it opens the contact. Automotive Relay Diagram Del City Automotive Relay Diagram Relays Relays are switches controlled by electrical power, like another switch, computer or control module. ... 87, and 87a are the switch pins. ... If you want a normally open relay, you will wire to 87. Although most relays are labeled on the bottom, for easy identification to the power Automotive Relay Guide | 12 Volt Planet Changeover relay : Two circuits (terminals 87 and 87a ) have a common terminal (30). When the relay is at rest 87a is connected to 30, and when the relay is energised 87 becomes connected to 30 (but never both at the same time). Relay with double output . Terminal 87 is linked to pin number 87b, giving double outputs from the single NO contact. Understanding Relays & Wiring Diagrams | Swe Check A normally open relay will switch power ON for a circuit when the coil is activated. A normally closed relay will switch power OFF for a circuit when the coil is activated. 5 Pin Relay 5 pin relays provide 2 pins (85 & 86) to control the coil and 3 pins (30, 87 & 87A) which switch power between two circuits.

The SPDT relay is one of the most useful configurations due to its flexibility it can be used as a switching device, to isolate circuits, to interrupt circuits and to interrupt and switch at the same ... Suggested Electric Fan Wiring Diagrams DaveBarton This type of relay will work for this application also, but you will not use pin 87a. In a changeover relay, the 87a pin will be “HOT” anytime the 87 pin is "OFF," so long as power is connected to pin 30.
