3.5 Digital Input and Output Modules
Input and output modules connect a PLC CPU with the process to be controlled. The digital
inputs are used for inputting control signals from the connected switches, buttons or sensors.
These inputs can read the values ON (power signal on) and OFF (no power signal). Digital out
-
put modules can switch external actuators ON or OFF.
The input signals can come from a wide variety of devices i.e.
쎲 Push buttons.
쎲 Rotary switches.
쎲 Key switches.
쎲 Limit switches.
쎲 Level sensors.
쎲 Flow rate sensors
쎲 Photo-electric detectors.
쎲 Proximity detectors (inductive or capacitive).
Proximity detectors usually provide a transistor output which can be either an NPN (sink)
or PNP (source) transistor.
Output signals forexampleareusedtocontrol:
쎲 Relays and contactors
쎲 Signal lamps
쎲 Solenoids
쎲 Inputs of other devices e. g. inverters.
