The 1756-RMC1 cable is an Allen-Bradley ControlLogix series connector cable. It is one meter or 3.3 feet long. The 1756-RMC1 connector cable can be used with Allen-Bradley ControlLogix 1756-RM2 and 1756-RM2K redundancy modules in redundant systems. It is the shortest cable available for these modules. The 1756-RMC1 connector cable can withstand a maximum ambient operating temperature of 70 degrees Celsius or 158 degrees Fahrenheit, and up to 95% non-condensing relative humidity.
Allen-Bradley 1756-RMC1 is the fiber optic communication cable needed to connect the ControlLogix redundant module. Its length is 1 meter or 3.28 feet. It is part of the Bulletin 1756-RMCx cable series, which is available in a variety of lengths. They are compatible with standard and extreme environment modules. Building the ControlLogix redundant controller system requires one or two of these cables. Since redundant modules and enclosures are not supplied with these connectors, order them separately before the system is assembled.
1756-RMC1 Redundant module Optical fiber cables are connected to the bottom of the module in the downward direction. Remove its protective cover before connecting. Because it contains optical fiber, do not make sharp turns on the cable. LC connector couplers can be used to prevent cable bending. This also allows easy connection and disconnection without removing the module from the case.
Ensure that the 1756-RMC1 connector passes through a location that is not prone to activities that could cause it to be crushed, worn, cut, or otherwise damaged. Redundant cable systems can tolerate one of multiple failures on a single channel. If both channels fail, network operations become unpredictable.
