Allen Bradley 1769-PA4 ControlLogix Description

Each ControlLogix I/O module maintains specific identification information that separates it from all other modules. This information assists you in tracking all the components of your system. For example, you can track module identification information to know which modules are in any ControlLogix chassis at any time. While retrieving module identity, you can also retrieve module status. I/O modules are the interface between controllers and field devices in a ControlLogix system. Digital I/O modules transfer data to devices that require just one bit to be represented (0 or 1). For example, a switch is open or closed, or a light is on or off.
