Product Description
The definition of the relay: It is an electrical control device, which is an electrical device that causes a predetermined step change in the controlled electrical quantity in the electrical output circuit when the change of the input quantity (motivation quantity) reaches the specified requirement. 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 automated control circuits, it is actually an "automatic switch" that uses small currents to control high-current operation. Therefore, it plays a role in the circuit such as automatic adjustment, safety protection, and conversion circuit.
The role of the relay: Relay is an automatic switching element with isolation function, widely used in remote control, telemetry, communications, automatic control, electromechanical integration and power electronic equipment, is one of the most important control components.
Relays generally have a sensing mechanism (input section) that can reflect a certain input variable (such as current, voltage, power, impedance, frequency, temperature, pressure, speed, light, etc.); there is the ability to achieve "through", " "Off" control of the implementation of the mechanism (output part); In the input and output parts of the relay, there is also an input mechanism for the isolated isolation, functional processing and the drive of the output part of the intermediate mechanism (drive part). As a control element, summarize it.
