Features:
- Extended-temperature ControlLogix-XT redundancy module
- Two single-mode fiber-optic redundancy channels
- 1000 Mbps redundancy communication
- Operation from -25 to +70 C
- Designed for paired 1756-A7XT or 1756-A10XT chassis
The module must be installed as a matched pair in corresponding chassis slots and connected directly with approved LC duplex single-mode fiber. Compatible firmware, XT chassis, XT power supplies, fiber routing, and system synchronization must be confirmed before service.
1756-RM2XT Allen-Bradley: Verify the partner catalog number, firmware, chassis type, slot position, fiber connection, power isolation, and redundancy synchronization before installation or replacement.

Important Notice: Official documents are provided through manufacturer sources. Accessories, manuals, cables, certificates and other items are not included unless listed in the stock item description.
- Maintaining controller operation during primary-chassis switchover
- Synchronizing paired ControlLogix-XT controller chassis
- Providing redundant control for continuous process operations
- Providing redundant control for batch process operations
- Supporting documented Logix SIS redundancy architectures
1756-RM2XT is applied in paired ControlLogix-XT chassis where the redundancy modules supervise operating states, exchange synchronization data, and support controlled switchover. Application engineering must confirm matching partner modules, corresponding slots, supported controllers, compatible firmware, direct fiber connections, and the required redundancy qualification procedure.
1756-RM2XT is compatible with matched 1756-RM2XT partner modules installed in the same slot of paired 1756-A7XT or 1756-A10XT chassis. Rockwell Automation documents support for ControlLogix 5570 and ControlLogix 5580 controller families and requires 1756-PAXT or 1756-PBXT power supplies. Confirm the complete system firmware and module compatibility before installation.
Rockwell Automation lists 1756-RM2XT with an Active Mature lifecycle status and a replacement available. Before replacement, record the complete catalog number, partner-module hardware and firmware, chassis type, slot position, fiber-cable routing, redundancy configuration and synchronization state. Use the current manufacturer replacement guidance and validate switchover operation before returning the system to service.

Technical notes
Use 1756-RM2XT only as a matched redundancy-module pair in supported ControlLogix-XT chassis. The partner modules must occupy the same slot, use compatible firmware, and connect directly with approved single-mode fiber. Verify system synchronization and redundancy switchover after installation.
