The Allen-Bradley 1756-RM2 ControlLogix Redundancy Module is a hardware component used to create a redundant control system with ControlLogix programmable automation controllers (PACs).

• Function: Enables redundant operation of ControlLogix controllers. This means you have a backup controller that can take over seamlessly in case of a primary controller failure, minimizing downtime.
• Data transfer: Supports high-speed data communication between the primary and secondary controllers using fiber optic cables. This ensures fast and reliable transfer of critical control information.
• Compatibility: Works with specific ControlLogix controller models, typically the 5570 series.
