The Allen-Bradley 1756-RMC3 is a vital fiber-optic communication cable designed for the ControlLogix Redundant Programmable Controller System, ensuring robust connectivity for redundancy modules once components are installed within their chassis. Measuring 3 meters in length, this cable, part of the Bulletin 1756-RMCx Cables, features LC connector couplers to facilitate easy, secure connections while minimizing the risk of damage from bending. Engineered to support both standard and extreme-environment ControlLogix Redundancy Modules, the 1756-RMC3 is essential for maintaining reliable network operations, even in the event of single-channel faults, by directing trunk cables separately to mitigate dual-channel disruptions.
