The Allen-Bradley 1756-RM2 is a ControlLogix Redundancy Module.

It’s part of a system designed to improve reliability and prevent downtime in industrial automation applications.

• Increased Reliability: It enables redundant operation of ControlLogix controllers. This means you have a backup controller that can take over if the primary controller fails.
• High Speed: It offers communication speeds of up to 1000 Mbps for fast data transfer between controllers.
• Fiber Optic Connectivity: It uses redundant fiber optic ports to eliminate a single point of failure in the communication link.
