Mini Relay 4 Pin Micro Relay Wiring Diagram

Determine that the relay is an iso micro type.

Mini relay 4 pin micro relay wiring diagram.

Look for a relay diagram or a relay schematic that is printed on the side of the relay to determine. Numbers of a relay. 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. 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.

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. Looking at the diagram we see the pinout of a typical 12v relay. Mini relay wireless switch 12v 433mhz remote control relay switch secure 1 channel micro receiver with transmitter system in latched mode dc 3 7v 5v 6v 7v 9v 12v 4 1 out of 5 stars 109 10 99 10. If the coil is not activated 30 will always be connected to 87a.

A open your fuse box and try see if there is any unused 4 pin mini or 4 pin micro relay sockets. You will notice that on the type b layout pins 86 and 30 are swapped over compared with the type a layout. Note that each pin is numbered. Relay diagrams pirate4x4.

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. These layouts are shown on the two 5 pin relays below pin 87a not present on 4 pin relays. When a relay contact is closed there is a closed contact when the relay is not energized. Here is a picture gallery about relay 4 pin wiring diagram complete with the description of the image please find the image you need.

When a relay contact is open the relay is not energized. Here we look at relay switch pin diagram and the different kinds of relay switches. Relays switches are used to open and close circuits electromechanically or electronically. 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.

87 and 87a are the two contacts to which 30 will connect. 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. 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.
