What 2 types of relay are commonly found in a vehicle?
Make & break relays are also known as Single Pole Single Throw (SPST) and changeover relays as Single Pole Double Throw (SPDT). This is based on standard switch terminology. There are other contact configurations discussed below but make & break and changeover relays are the most commonly used.
What is 85 and 86 on a relay?
85 and 86 are the coil pins while 30, 87, and 87a are the switch pins. 87 and 87a are the two contacts to which 30 will connect. If the coil is not activated, 30 will always be connected to 87a. You can think of this as the switch in OFF.
What are the types of 4 pin relay?
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.
Which relay is mostly used?
Electromagnetic relay
Electromagnetic relay is the simplest, oldest and most widely used relay. Its basic components are coils, magnetic cores, armatures, springs and contacts. The magnetic system is used to convert the input current into the mechanical power required for contact closure.
What are 3 types of start relays?
Several types of starting relays are used to assist in the starting of single-phase compressors. These include the current relay, potential relay, and PTC (positive temperature coefficient) relay.
Are all automotive relays the same?
The problem is, not all relays are the same. Many relays, if installed for the wrong application, could and will cause a short (Internal Relay Circuit) and most likely cause functionality issues or even damage to the vehicle computer systems.
What are the three types of relays?
The three main types of relays are electromechanical, solid-state, and reed.
What is L1 and L2 in a relay?
1. The two vertical lines that connect all devices on the relay logic diagram are labeled L1 and L2. The space between L1 and L2 represents the voltage of the control circuit. 2. Output devices are always connected to L2.
Can you swap 30 and 87 on a relay?
If your relay is a SPDT “changeover” relay, you can independently jumper 30 to 87 and then 30 to 87a to manually test the turn-on of both high-current loads.
What does A1 and A2 mean on a relay?
What Do A1 and A2 Mean on a Contactor? A1 and A2 on a contactor typically refer to either end of the electromagnetic coil assembly. Most contactor manufacturers use A1 and A2 to designate the two terminals connecting electrical power to the contactor's magnetic coil.
What is an automotive relay?
Automotive relays are the common type of electromechanical relay that are used in all types of vehicles, like car, trucks, vans and trailers. They enable a small current flow circuit to control and operate a higher current circuit in vehicular applications.
What is the different types of relays?
The three main types of relays are electromechanical, solid-state, and reed.

Are all automotive relays the same?
The problem is, not all relays are the same. Many relays, if installed for the wrong application, could and will cause a short (Internal Relay Circuit) and most likely cause functionality issues or even damage to the vehicle computer systems.
What is T1 and T2 in relay?
Terminals T1 and T2 are a thermally activated contact on the resistor to indicate an overheat condition of the resistor. The contacts are normally closed and open once the braking resistor temperature reaches 120 degrees Centigrade. The minimum voltage/current for these contacts is 24VDC at .
Do relays need AC or DC?
The operating voltage of a relay is generally in DC. Small signal relays and low voltage power relays are usually in DC, but mains control relays and contactors quite frequently have AC coils. The rest of the terminals of a relay are used to connect either a AC(generally 50/60Hz) or DC circuit.
What are 3 types of start relays?
Several types of starting relays are used to assist in the starting of single-phase compressors. These include the current relay, potential relay, and PTC (positive temperature coefficient) relay.
Why relay is used in automotive?
A car relay switch is used to enable a low amperage circuit to switch on and off a higher amperage circuit like headlights, relays are also used to switch multiple things at the same time using one output. A single output connected to multiple automobile relays allow opening and/or closing simultaneously.
What is relay in BMS?
This relay is used by the BMS to control a battery charger (or other charge source in a defined charging period). If enabled, this relay output on the BMS will be driven low to allow charging until the BMS determines the charger should shut off, at which point it will float high.
