The coil of a relay is a(n):

Explanation:
A relay coil is an actuator. When you apply electrical energy to the coil, it creates a magnetic field that pulls the relay armature and moves the contacts. That movement is a physical action that controls a high-power circuit, which is exactly what an output device does—convert electrical energy into motion to drive a load. The coil itself doesn’t sense a process signal or feed information back; it responds to a control signal and produces the mechanical action that enables the switch to operate. That’s why the coil is classified as an output (actuator) device.
