Hella 5 Pin Relay Diagram

Pin 85 should be connected to a vehicle ground source.

Hella 5 pin relay diagram.

When second one arrived it was the correct hella timer relay. Four pin relays do not use this terminal see reference 2 under the common pin designations chart. As switch amplifiers used to control electrical loads in plug in standard models these electronic components can be controlled by control units. Pin 30 should be connected to a key on switched 12 volt source.

In the illustrated example see diagram the relay serves to open and close the circuit which connects the horns to the battery. If you are switching from a standard relay to this relay you will have to change your wiring. The most common automotive relay is the 4pin normally open relay. I cover 3 4 and 5 pin relays and all you need is a 12v source a multimeter and a test.

Hella relays feature diodes or resistors to. In the normal inactive setting the solid state relay interrupts the circuit. 4 5 1951 first hot wire flasher unit 1960 a relay with metal housing. The first modular system 1969 wipe wash interval control unit 1970 k relay.

They have both normally open and normally closed connection pins. Mechanical threshold voltage controller for windshield wipers 1965 e relay. Best connections 12voltwire c. The electro mechanical plug in relay has been one of hella s core products for many years.

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. Hella offers a wide range of relays for different applications. Current controlled relay for direction indicator lamps bi stable relay for switching between low and high beam. Flasher unit operates 2 bulbs on either side of towing vehicle plus an additional bulb on either side of two trailers.

Determine which wire leads to the second electrical device if equipped. 2 1 1 8 x 21w. In this video i show you how to wire a 12 volt automotive bosch style relay. Slide this wire s wire terminal onto a hella five pin relay s terminal labeled 87a this terminal turns hot when the control circuit deactivates.

6 pin flasher unit features. When the coil is activated power will be switched from the normally closed pin to the normally open pin. Warning this relay will fit in a standard automotive relay connector but the pins are not the same wiring configuration. This video covers both 4 and 5 pin 12vdc relays.
