A Coil Relay is used to control and manage the flow of electrical power within the power module unit. It operates based on the principle of electromagnetic induction, where the coil within the relay is energized by a 120VAC power source. When energized, the coil generates a magnetic field that causes the relay's internal contacts to mechanically switch positions, either opening or closing the circuit.Attributes:• Helps to provide quick and efficient control over the flow of electrical current• Prevents electrical noise, interference, and potential short circuits by providing electrical isolation between the control circuit and the switched circuitApplications:A Coil Relay acts as a switch that can isolate or connect electrical loads within the power module, allowing for the precise activation or deactivation of specific circuits in the unit and maintaining integrity and reliability.
