Input Modules
Digital input modules interface to sensing devices and detect whether they are On or
Off.
Digital input modules convert AC or DC On/Off signals from user devices to appropriate
logic level for use within the processor. Typical input devices include the
following:
- Proximity switches
- Limit switches
- Selector switches
- Float switches
- Push button switches
When you design systems with digital input modules, consider these factors:
- Voltage necessary for your application
- Current leakage
- Whether your application uses sinking or sourcing wiring
