Electromagnetic Relay

Electromagnetic relays are automatic control devices that work on the principle of electromagnetic induction and are widely used in switching, protecting and isolating control circuits. They have the characteristics of simple structure, reliable operation, strong adaptability, and can operate stably in harsh working environments. Electromagnetic relays are usually used in the control systems of electromechanical equipment to ensure the safety and stability of the equipment.

What is an electromagnetic relay and how does it work?

An electromagnetic relay is a switch that uses an electromagnet to open or close one or more sets of contacts. When a current flows through the relay coil, it creates a magnetic field that attracts an armature, which operates the contacts. The contacts close or open circuits, switching the current on or off.
