Mini Relay 4 Pin Micro Relay Wiring Diagram

An iso micro relay has the control circuit connected to pin 86 and pin 85 and the load circuit connected to pin 30 and pin 87 or 87a.

Mini relay 4 pin micro relay wiring diagram.

A open your fuse box and try see if there is any unused 4 pin mini or 4 pin micro relay sockets. 85 and 86 are the coil pins while 30 87 and 87a are the contact pins. 4 pin relay 4 pin relays use 2 pins 85 86 to control the coil and 2 pins 30 87 which switch power on a single circuit. In a diode protected relay mini relays must be pin 85 power pin 86 ground micro relays must be pin 2 power pin 1 ground.

Relay diagrams pirate4x4. The automotive iso mini relays we have been looking at above are typically available in two types of pin layout designated type a and type b layouts. The iso defines this type of relay as 1 inch 2 5 cm by 1 inch 2 5 cm by 0 5 inches 25 4 mm by 25 4 mm by 12 7 mm. Numbers of a relay.

When a relay contact is closed there is a closed contact when the relay is not energized. The difference between a 4 and 5 pin relay is that a 4 pin relay is used to control a single circuit whereas a 5 pin relay switches power between two circuits. Here is a picture gallery about relay 4 pin wiring diagram complete with the description of the image please find the image you need. Relays switches are used to open and close circuits electromechanically or electronically.

I have attached the electrical wiring diagram from the turn indicator i believe what you will discover is that the turn signal and hazard the 8 pin flasher relay toyota is using here is kinda alien to me. When a relay contact is open the relay is not energized. Looking at the diagram we see the pinout of a typical 12v relay. If the coil is not activated 30 will always be connected to 87a.

These layouts are shown on the two 5 pin relays below pin 87a not present on 4 pin relays. Protection diode and spike suppression resistor for automotive relays. Look for a relay diagram or a relay schematic that is printed on the side of the relay to determine. Note that each pin is numbered.

You will notice that on the type b layout pins 86 and 30 are swapped over compared with the type a layout. Here we look at relay switch pin diagram and the different kinds of relay switches. 4x4 and off road forum inside relay 4 pin wiring diagram image size 640 x 480 px and to view image details please click the image.
