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. 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. 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. 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. 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. 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.

When the coil of the relay is at rest (not energized), the common terminal (30) and the normally closed terminal (87a) have continuity. When the coil is energized, the common terminal (30) and the normally open terminal (87) have continuity. 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!!!) 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. Relay A relay is an electrically operated switch. Many relays use an electromagnet to mechanically operate a switch, but other operating principles are also used, such as solid state relays. Öffner und Schliesser Elektricks Der Schliesser schliesst den Kontakt wenn er betätigt wird. Auch Arbeitskontakt genannt (wenn er betätigt wird, also arbeitet, mach er Kontakt). Klemmen auf Schützen, Relais oder sonstigen Schaltern die Schliesser sind, werden mit den Ziffern 3 und 4 (Eingang und Ausgang) oder auch NO (Normally Open) oder A (Arbeitskontakt) gekennzeichnet.
