4 pin relay is used to control a single circuit.
4 pin relays use 2 pins (85 & 86) to control the coil and 2 pins (30 & 87) that switch power on a single circuit. There are 2 types of 4 pin relay available; normally open or normally closed. A normally open relay will switch power ON for a circuit when the coil is activated. A normally closed relay will switch power OFF for a circuit when the coil is activated.
We have a wide range of relays from Automotive flashers, Automotive Relays, Communication Relays, Connects/Bases to General purpose and Heavy Duty relays.
What are Automotive relays?
We offer many types of PCB Relays useful for a range of appliances. PCB Relays are electro-mechanical components that allow effective flow of current. They commonly use an electromagnet (coil) to operate their internal mechanical switching mechanism (contacts). When a relay contact is open, this will switch power ON for a circuit when the coil is activated.
Where are Automotive Relays used?
Automotive relays are commonly used by the automotive industry and marine & boat building industry. Automotive relays are available with 4pin and 5pins. This type of relay has either normally closed or normally open contacts and can handle up to 30 or 40 amps.
Voltages are available from 5v, 12v and 24v as standard. 24V options are often used within the automotive industry as well as marine applications.
Relays are commonly used by the following industries but are not limited to.
