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. RELAYS AND RELAY DEVICES PRODUCTS AND APPLICATIONS hella armature is pulled in, opens the break contact (87a) and switches over to the make contact (87). A change over A change over relay can be used as either a make or a break relay. 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. Never even thought about it. Relay Function and Operations BusTekHub Terminal 87a – is connected to terminal 30 when the relay is OFF (not energized). Terminal 87 – is connected to terminal 30 when the relay is ON (energized). Terminal 86 – is the power supply for the coil. 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. 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.
