The ControlLogix architecture provides a wide range of input and output modules to span many applications, from high-speed digital to process control. The ControlLogix architecture uses Producer-Consumer technology, which allows input information and output status to be shared among multiple ControlLogix controllers.
Each ControlLogix I/O module mounts in a ControlLogix chassis and requires either a removable terminal block (RTB) or a 1492 interface module (IFM) to connect all field-side wiring. RTBs and IFMs are not included with the I/O modules. They must be ordered separately.

Digital I/O Modules
The 1756 digital I/O modules support these features.
· Variety of voltage interface capabilities
· Isolated and nonisolated module types
· Point-level output fault states
· Direct-connect or rack-optimized communication
· Field-side diagnostics on select modules
In addition, you can select these types of digital I/O modules.
Digital I/O Type | Description |
Diagnostic | These modules provide diagnostic features to the point level. These modules have a D at the end of the catalog number. |
Electronic fusing | These modules have internal electronic fusing to prevent too much current from flowing through the module. These modules have an E at the end of the catalog number. |
Individually isolated | These modules have individually isolated inputs or outputs. |
