Common Module Features
Input Module Compatibility ControlLogix digital input modules interface to sensing devices and detect
whether they are On or Off.
ControlLogix 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 designing systems with ControlLogix input modules, consider these
factors:
• Voltage necessary for your application
• Current leakage
• Whether you need a solid state device
• Whether your application should use sinking or sourcing wiring
