Automatic regulation and safety protection: Relays play a role in automatic regulation and safety protection in circuits, and can effectively control circuits by controlling large currents with small currents.
Multiple types and application scenarios: There are various types of relays, such as electromagnetic relays, solid-state relays, etc., widely used in fields such as power protection, automation, motion control, remote control, measurement, and communication.
High sensitivity and multiple signal responses: Relays can respond to various signals, such as voltage, current, temperature, speed, and pressure, with extremely high sensitivity and easy adjustment of input and output quantities.
Small size and light weight: The contact capacity of the relay is small, using point contact form, without arc extinguishing device, and the volume and weight are relatively small.
Fast response and stable operation: Relays have the characteristics of fast action, stable operation, and long service life, and are suitable for various automation control systems.
