How PLC Outputs Work - Discrete and Analog

There are basically two different kinds of PLC outputs, Discrete and analog. Discrete inputs are either 'ON' or 'OFF'; 1 or 0. You can think of them as a single light bulb. Analog outputs have a range to them. They are outputs that usually will control proportional valves, drive speeds, etc. They usually have one of the following signals that are outputted from the PLC: 4-20mA, 0-10VDC, 1-5VDC.
