Relay is the use of electromagnetic principle or other physical effects to achieve the circuit automatic control and protection of the electrical control device, when the input (excitation) changes to meet the specified requirements, in the electrical output circuit to make the controlled amount of a predetermined step change in an electrical appliance.It can automatically turn on or off the small current in the circuit according to the change of the input signal (such as the change of voltage and current), so as to control the opening and closing of the large current circuit, and realize the remote, automatic or procedural control of the circuit.

Relay: Relay (Relay) is widely used in industrial automation, household appliances, automotive electronics, communication equipment and other fields. In the field of industrial automation, relays are often used in PLC (programmable logic controller) systems to achieve accurate control of production equipment; In household appliances, such as air conditioners, washing machines, etc., relays are responsible for controlling the switching of different functional modules and protecting circuits; In the field of automotive electronics, relays are involved in the electrical management of key links such as engine starting and lighting control. In the power system, the relay is used for the protection and automatic control of the power grid, such as overload protection, short circuit detection, etc. From the development of traditional electromechanical relays to solid-state relays, magnetic holding relays, photoelectric relays, etc., they have significantly improved in response speed, service life, reliability and so on, and better adapt to the needs of modern science and technology.
