The Allen-Bradley 1756-RMC1 is a one-meter fiber-optic communication cable designed for linking ControlLogix redundancy modules, essential for establishing a ControlLogix Redundant Controller System. Part of the versatile Bulletin 1756-RMCx Cable Series, this cable is compatible with both standard and extreme-environment modules, although system assembly requires separate ordering due to the lack of included connectors with redundancy modules and chassis. Notable for its LC connector coupler, the 1756-RMC1 ensures efficient connections while preventing sharp bends; however, it should be routed safely to avoid potential damage from environmental factors, maintaining reliability in network operation.
