Principles of Machine Control
The controller consists of a built-in power supply, central processing unit (CPU),
inputs, which you wire to input devices (such as pushbuttons, proximity sensors,
limit switches), and outputs, which you wire to output devices (such as motor
starters, solid-state relays, and indicator lights).
