Features:
- ControlLogix enhanced redundancy module
- It is part of the Programmable Automation Controller (PAC)
- Used to implement controller redundancy
The 1756-RM comes in two series: A and B. The A series is essentially an enhanced version of the previous series, but different series of 1756-RM can coexist in the same redundancy configuration. It is strongly recommended to install 1756-RM from the same series to maximize the operational efficiency of the redundancy setup. When used with redundancy modules from the same series, speeds up to 100 Mbps are possible.
The 1756-RM is equipped with a single-mode LC fiber optic connector. It requires a 1756-RMCx redundancy cable to synchronize the operation of the redundant controller pair. This controller can be configured to set up redundancy using the redundancy configuration tool, and the overall parameters of the module can be configured using Studio 5000 Logix Designer.
The 1756-RM Allen Bradley Redundancy module may still be available for purchase and support from Moore Automated Company beyond End-Of-Life (EOL) by the manufacturer (OEM).

Important Notice: Other accessories, manuals, cables, calibration data, software, etc. are not included with this equipment unless listed in the above stock item description. All prices are shown in USD.
This module is also compatible with 1756-PA72, 1756-PA75, 1756-PB72, 1756-PB75 Standard Power supply. It is a single slot module and may be installed to any available slot in the chassis. The redundant pair must have the same configuration as to the partner chassis.
The 1756-RM has a Current draw of 4 mA at 1.2VDC, 1.2 mA at 5.1VDC and 120 mA at 24VDC operation.
Software Configuration: Fine-tuning, synchronized fault checking, and deeper asset monitoring are performed through the Redundant Module Configuration Tool (RMCT).
Lifecycle Status: The manufacturer has officially discontinued the older 1756-RM series. Modern high-availability systems typically migrate to the newer 1756-RM2 or 1756-RM3 platform during transition or upgrades.
Note: 1756-RM modules cannot be mixed with 1756-RM2 hardware in the same redundant chassis pair.
