A coil is considered to be a...?

In sensor logic systems, the controller reads inputs from sensors and drives outputs to actuate devices. A coil is the device that the control logic energizes to create a physical action—such as activating a relay, solenoid, or indicator lamp. That makes it an output. It isn’t a sensor, and it isn’t an input, because its role is to produce an actuator response when the logic energizes it. While a coil can be an inductor in purely electrical terms, in this context its function within ladder or sensor logic is as an output.
