The Allen-Bradley/Rockwell Automation 1756-RMC10 cable is a redundant module connector cable. This device is available in the Allen-Bradley ControlLogix family and can be used with certain ControlLogix redundant modules. The 1756-RMC10 Redundant Module Connector cable is the longest redundant module cable in the ControlLogix series. It is 10 meters or 32.81 feet long. The 1756-RMC10 Redundant module connector cable can be used with Allen-Bradley 1756-RM2, 1756-RM2K, and 1756-RM2XT ControlLogix redundant modules.
The Allen-Bradley 1756-RMC10 is part of the Bulletin 1756-RMCx cable family and is available in a variety of lengths. This optical fiber communication cable is used to connect the ControlLogix redundant module in a chassis pair. It is an important part of building the ControlLogix redundant programmable controller system. The 1756-RMC10 is sold separately from other system components and can be used with standard and extreme environment modules.
The 1756-RMC10 redundant module connector is 10 meters (32.81 ft) in length. It comes with a protective cover and should be removed before assembly. It is placed in a downward direction and attached to the bottom of the module. LC connector couplers can be used between transmit and receive connectors. The coupler helps prevent the cable from bending sharply. This also makes connecting and disconnecting quick and easy, even without removing the module from the case.
Install the 1756-RMC01 fiber optic cable where it is protected from wear, cutting, crushing, or other damage. In a redundant controller system, the cable can tolerate failure on a single channel. However, if problems occur on both channels at the same time, network operations can become unpredictable. To avoid this, route the trunk separately. This reduces the risk of damage to both.
