A Relay Coupling is a type of electrical isolation that uses a relay to separate the control circuit from the load circuit. This is done by using the relay's contacts to switch the load circuit on and off, without any direct electrical connection between the two circuits. Relay coupling is used where it is necessary to isolate the control circuit from the load circuit for safety or performance reasons.Attributes: • Manufactured to precise specifications and are built for durability, and reliability• Provide a switching mechanism for the electrical systemApplications:A Relay Coupling is used to protect the electrical system from voltage spikes and other electrical disturbances.
