Name: Automobile relay
Model: High current relay
Relay is an electrical control device. It is an electrical device that causes a predetermined step change of the controlled quantity in the electrical output circuit when the change of input quantity reaches the specified requirements.
It has the interaction between the control system and the controlled system.
Usually used in automatic control circuits, it is actually a kind of "automatic switch" that USES small current to control the operation of large current.So in the circuit plays the role of automatic regulation, safety protection, conversion circuit.
Relay is an automatic switch element with isolation function, which is widely used in remote control, telemetry, communication, automatic control, mechatronics and power electronic equipment. It is one of the most important control elements.
