How Does Omron Relay Work

OMRON provides General-purpose Relays, I/O Relays, Power Relays, Latching Relays, and Ratchet Relays. A relay consists of an electromagnet that receives an electric signal and converts it to a mechanical action and a switch that open and closes the electric circuit.

How does a relay sensor work?

When the control circuit is powered, the relay shuts and allows the current flow between two connected points. When the control command is turned off the circuit opens. … When an electric current crosses the coil a magnetic field is formed over the armature that attracts it and activates the contacts.

How do magnetic relays work?

Working Principle of Relay It works on the principle of an electromagnetic attraction. When the circuit of the relay senses the fault current, it energises the electromagnetic field which produces the temporary magnetic field. This magnetic field moves the relay armature for opening or closing the connections.
