Input Devices
PCs can receive input from either automated or manual devices. The PC
could receive data from the user via a pushbutton switch, keyboard, or simi-
lar device. Automated input could come from a variety of devices: micro-
switches, timers, encoders, photosensors, and so on. Some devices, like the
Limit Switch shown below, turn ON or OFF when the equipment actually
makes contact with them. Other devices, like the Photoelectric Switch and
Proximity Switch shown below, use other means, such as light or inductance,
in order to get information about the equipment being monitored.

Output Devices
A PC can output to a myriad of devices for use in automated control. Almost
anything that you can think of could be controlled (perhaps indirectly) by a
PC. Some of the most common devices are motors, Solenoids, Servomotors,
Stepping Motors, valves, switches, indicator lights, buzzers, and alarms.
Some of these output devices, such as the motors, Solenoids, Servomotors,
Stepping Motors, and valves, affect the controlled system directly. Others,
such as the indicator lights, buzzers, and alarms, provide output to notify per-
sonnel.
