Allen-Bradley 1756-RM2XT | Redundancy Module with Extended Temperature for ControlLogix XT Systems
Overview
The Allen-Bradley 1756-RM2XT is an XT (Extended Temperature) version of the ControlLogix redundancy module, designed for use in high-availability automation systems operating in extreme environments. It enables synchronized operation between primary and secondary ControlLogix controllers, providing seamless redundancy and system reliability.
Key Features
-
Redundancy Control – Synchronizes two ControlLogix controllers for failover capability
-
XT Rated – Operates in extended temperature ranges for harsh environments
-
High-Speed Synchronization – Ensures real-time controller data replication
-
Redundant Chassis Support – Enables high availability in mission-critical applications
-
Status LEDs – Provide clear diagnostics for redundancy status
-
Compatible with Fiber Cables – Use with 1756-RMC cables for redundancy link
-
Compact Slot Design – Fits standard 1756 chassis slots
Technical Specifications
-
Catalog Number: 1756-RM2XT
-
