What is a 280 relay?

Omron’s G8V micro 280 relays are an ISO 280 footprint used in most modern automotive vehicles today. Featuring either SPST or STDT layouts, these low profile automotive relays are capable of switching 20 A resistive on the normally open contact with a 60 A inrush.

What is micro relay used for?

Bosch micro relays are used in a wide range of vehicles. They perform switching operations and allow rated switching currents of up to 25 A. Thanks to their design, they are an ideal solution for quick and easy service tasks.

What is ISO 280?

Song Chuan’s ISO 280 Micro Relays are a smaller version of a standard relay. As the name would suggest, this micro relay is meant to fit into Mini ATM fuse boxes and save space. The resistor in the micro relay protects equipment and applications against high voltage spikes. Available in 12 volt and 24 volt DC.

How does a micro relay work?

The size of a ISO MICRO relay is a 1″ x 1″ x 1/2″ square (1/2 as thick as a Mini relay). Both 4 and 5 pins designs are used. When the switch is closed (shown left), current flows through the coil from positive to negative as shown in red. This current flow creates a magnetic field around the coil.

What is 85 on a relay?

Realizing that 85 and 86 are the coil pins, these pins will be transferring the current through the coil. 85 will be used to ground your relay, while 86 will be connected to the switchable power. 87 and 87a will be connected to your controlled accessories that you wish to turn on and off with your relay.

What is a micro ISO relay?

Product Overview. A series Micro ISO relay is a plug-in automotive relay. It is used in ABS control, blower fans, cooling fan, door control, door lock, fuel pump, heated front screen, immobilizer, interior lights, seat control, seatbelt pretensioner, sun roof, trunk lock, valves, window lifter and wiper control.

How do you test a micro relay?

The only tool required to check a relay is a multimeter. With the relay removed from the fuse box, the multimeter set to measure DC voltage and the switch in the cab activated, first check to see if there are 12 volts at the 85 position in the fuse box where the relay plugs in (or wherever the relay is located).
