Relay Applications

Relays are electrical control devices that are used to create a predefined step change in the controlled amount of an electrical appliance when the input quantity (excitation quantity) changes to satisfy the specified requirements. The control system, also known as the input circuit, and the controlled system are interconnected (also called the output circuit). It is actually a "automatic switch" that manages the operation of a big current with a little current, and is frequently employed in automatic control circuits. As a result, it functions as the circuit's automatic regulation, safety protection, and conversion circuit.

Relay Main Functions

  1. Extending the control range: Depending on the various contact group configurations, a multi-contact relay control signal up to a particular value can switch, open, and turn on many circuits simultaneously.
  2. Amplification: Using sensitive relays, intermediary relays, etc., you can control a very high-power circuit with a very tiny amount of control.
  3. Integrated signals: For instance, when several control signals are applied in a specific way to a multi-winding relay, they are compared and integrated to provide a preset control effect.
  4. Automatic, remote control, and monitoring: Relays on automatic equipment, for instance, can form programmed control lines with other electrical appliances to achieve automated operation.
