Industry Overview

A relay is a control component that automatically disconnects when the input parameters (such as electrical, magnetic, optical, thermal, acoustic, etc.) in a circuit reach a specified value, causing a predetermined step change in the output parameters of the circuit. In circuits, relays mainly serve to control, protect, regulate, and transmit signals

The role of breath. The relay has an induction mechanism that reflects external input parameters, an execution mechanism that controls the on and off of the controlled circuit, and an intermediate comparison mechanism that compares, judges, and converts input quantities.

Relay is an important component in automatic control systems, remote control and telemetry systems, and communication systems. It is widely used and has a wide variety of types. It can be classified according to different standards, such as working principle, structural characteristics, contact load, external dimensions, protection features, contact form, and product use.
