What is the use of automotive relays
2023-02-22
The role of the automotive relay is to control the on-off of one circuit to control the intermediate link of the next circuit on-off. In other words, the function of the automotive relay is to control the magnitude and on-off of the current.
Like the general relay, the relay plays the role of "switch" in the electrical automation industry, that is, the intermediate link that controls the on-off of one circuit to control the on-off of the next circuit. Therefore, the function of the automotive relay is to control the magnitude and on-off of the current.
The function of the relay is to use the switch to control the relay coil, and then the working contact of the relay is closed or disconnected. One end of the contact is connected to the main line current, and the other end is connected to the electrical appliance to be controlled, so as to realize small current control of large current and prevent switching It is a large current that burns out the switch and protects the circuit and the switch.
As long as you lift the hood to find the relay installation box, you can find the trace of the relay. Car lights, wipers, starters, air conditioners, electric seats, electric doors and windows, anti-lock brakes, suspension controls, audio, etc. all use relays. The control relay has two main parts, one is the controlling system and the other is the controlled system. Controlling large current with small current is the characteristic of control relay.
