What Is A Relay Box?

A relay box is an electrical control device used to implement functions such as automatic switching, safety protection and conversion circuit in a circuit.

The relay box is usually composed of coils and contacts, with an interactive relationship between the control system (input loop) and the controlled system (output loop).

Relays are widely used in power system, automation control, mechatronics and power electronic equipment, and are one of the most important control components.

The following are some of the main features and functions of relays:

Automatic adjustment: The relay can automatically adjust the controlled amount in the circuit according to the change of the input amount.

Amplification: Through relays, a small amount of control can control a large power circuit.

Integrated signal: After multiple control signals are input into the relay, they can be comprehensively compared to achieve the predetermined control effect.

Automatic, remote control, monitoring: Relays can be combined with other electrical appliances to form program control lines to achieve automatic operation.

There are different types of relays, including electromagnetic relays, solid relays, temperature relays, time relays, etc. They play an important role in electronic production.
