Wofür ist der Anschluss 87A an einem Relais? Ein Relais mit "87" und "87a" ist ein Umschalt Wechselrelais, es schaltet zwischen "87" und "87a" um. Du kannst das Relais gegen ein normales mit einem Ausgang "87" austauschen, Hella oder Boschnummer könnt ich dir raussuchen, kannst es aber auch drinlassen, wenn der Kontakt 87a nicht angeschlossen ist. Powerdynamo, Funktion und Anschluß des Ausschaltrelais es wird ein normales KFZ Relais ohne Kontakt 87a genutzt. Es muss unbedingt eines mit Ruhestromkontakt sein (Klemme 87a, das ist eine in der Mitte des Relaisbodens siehe Bild. Ist dort keine Klemme hat das Relais keinen Ruhestromkontakt und ist nicht nutzbar!!!) Automotive Relay Guide | 12 Volt Planet 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. Clarification on 87a Terminal of Relay the12volt Clarification on 87a Terminal of Relay I am installing a set of air horns on a truck and I would like to confirm a connection on the relay please. This air horn set comes with two compressors driving one trumpet each. The instructions are not very detailed, but the box does show a diagram which i How to guides Understanding relays The terms used to describe the contact points thus: pin 30 switches between 87a and 87, so it is “ mon” to both and is usually referred to as COM. In the relay’s normal condition, at rest, pin 30 is connected to pin 87a, making pin 87a “Normally Closed” or NC Pin 87 is not connected to pin 30 at rest, so its status is “Normally Open” or NO. 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. What is a Changeover Relay? | Switch Relay Definition What is a changeover relay? The most common changeover function relays are produced to switch a single feed line (usually positive position 30) between two active functions in a circuit, the relay is switched manually via a toggle push switch or remotely through the circuit. Why Do Relays Use 30, 85, 86, 87, 87a? the12volt The relay you described is Single Pole Double Throw. As far as the numbers, not sure. Never even thought about it. As far as the numbers, not sure.
