The A-B 1756-RM2K Redundancy Module is a part of the Allen-Bradley ControlLogix Redundancy System by Rockwell Automation. It enables high availability for critical control systems by providing a backup for your main processor.

• Redundancy: It works in pairs to create a fault-tolerant system. If the primary processor fails, the secondary processor, connected through the redundancy modules, takes over seamlessly with minimal disruption to your operations.
• Communication Bridge: It acts as a bridge between two ControlLogix chassis, allowing them to exchange control data and synchronize their actions. This ensures that both processors have the same information and are operating in unison.
