Relay (English name: relay) is an electrical control device that causes a predetermined step change in the controlled variable in the electrical output circuit when the input quantity (excitation quantity) changes to meet the specified requirements. It has an interactive relationship between the control system (also known as the input loop) and the controlled system (also known as the output loop). Usually used in automation control circuits, it is actually an "automatic switch" that uses low current to control high current operation. Therefore, it plays a role in automatic regulation, safety protection, and circuit conversion in the circuit.
Development History
In the 18th century, scientists believed that electricity and magnetism were two physical phenomena that were unrelated to wind, horses, and cows. After Danish physicist Oster discovered the magnetic effect of electric current in 1820, British physicist Faraday discovered the phenomenon of electromagnetic induction in 1831. These findings confirm that electrical energy and magnetic energy can be converted into each other, laying the foundation for the birth of electric motors and generators later on; Humans have entered the electrical age through these inventions and creations. In the 1830s, American physicist Joseph Henry invented relays using electromagnetic induction phenomena while studying circuit control. Early relays were electromagnetic relays, which used the phenomenon of magnetic force generation and disappearance of electromagnets during power on and off to control the opening and closing of another circuit with high voltage and high current. Its appearance enabled smooth remote control and protection of the circuit. Relay is a great invention and creation of human technology, which is not only the foundation of electrical engineering, but also an important foundation of electronic technology and microelectronics technology.
Main role: Editor
Relays are automatic switching components with isolation functions, widely used in remote control, telemetry, communication, automatic control, mechatronics, and power electronic equipment. They are one of the important control components.
Relays generally have sensing mechanisms (input parts) that can reflect certain input variables such as current, voltage, power, impedance, frequency, temperature, pressure, speed, light, etc; There is an executing mechanism (output part) that can achieve "on" and "off" control of the controlled circuit; Between the input and output parts of the relay, there is an intermediate mechanism (driving part) that couples and isolates the input quantity, performs functional processing, and drives the output part.
As a control component, in summary, relays have the following functions:
1) Expand control range: For example, when the control signal of a multi contact relay reaches a certain value, multiple circuits can be switched, disconnected, and connected simultaneously according to different forms of contact groups.
2) Amplification: For example, sensitive relays, intermediate relays, etc., can control circuits with high power with a very small control quantity.
3) Integrated signal: For example, when multiple control signals are input into a multi winding relay in a prescribed form, they are compared and integrated to achieve the predetermined control effect.
4) Automatic, remote control, monitoring: For example, relays on automatic devices, together with other electrical appliances, can form program control circuits to achieve automated operation.
