What are Control Relays?
Control relays are electromechanical devices used to control the operation of various electrical circuits and devices. They consist of a coil, which when energized, generates a magnetic field that pulls in an armature or contact assembly to make or break electrical connections within the relay.
Here’s how they typically work:
- Coil: The relay coil is usually made of copper wire wound around an iron core. When an electric current is passed through the coil, it creates a magnetic field around it.
- Contacts: Control relays have one or more sets of contacts that open or close when the coil is energized.... Read More
