What is the function of a control relay in a motor control system?

The function of a control relay in a motor control system is primarily to switch the circuit on and off. Control relays act as electrically operated switches that can control larger currents or voltage levels by using a smaller input signal. When the relay coil is energized, it creates a magnetic field that pulls in a movable armature, effectively closing the circuit to the load. This design allows for the safe and effective operation of motors and other devices within the system, enabling them to be controlled remotely or automatically based on various conditions.

Control relays play a crucial role in automating processes, providing the ability to start and stop motors based on input from other controls or sensors, thus ensuring efficient operation and control of motorized equipment.
