Description

The Allen-Bradley 1756-RMC10 is a 10-meter (32.81 feet) duplex single-mode fiber-optic communication cable engineered for the ControlLogix 1756 platform. This cable serves as the vital synchronization link for ControlLogix redundancy modules, including the 1756-RM, 1756-RM2, 1756-RMXT, and 1756-RM2XT. It enables high-speed, deterministic data transfer between primary and secondary chassis, supporting zero-downtime hot-backup configurations in critical industrial automation environments.

Features

  • Industrial-grade duplex LC connectors for secure, reliable mating with redundancy module transceivers.
  • Single-mode fiber construction providing complete immunity to EMI and RFI interference.
  • Optimized for long-distance routing between separate control cabinets.
  • Supports high-speed memory and I/O state synchronization for seamless failover.
  • Designed for robust performance in demanding process control applications.

Installation Guidelines

  • Ensure the cable is routed through protected conduits or wire ducts to prevent physical damage.
  • Maintain the manufacturer-specified minimum bend radius to avoid damaging the internal glass fibers.
  • Use separate physical paths for redundant cable runs to mitigate the risk of simultaneous channel failure.
  • Inspect LC connectors for dust or debris before insertion; use appropriate fiber-optic cleaning tools if necessary.
  • Avoid excessive mechanical strain on the connectors during cabinet installation and maintenance.

FAQ

What is the primary function of the 1756-RMC10 cable?

The 1756-RMC10 acts as the physical communication bridge between two ControlLogix redundancy modules, allowing them to synchronize memory and I/O states to maintain system operation during a controller failure.

Is this cable susceptible to electrical noise?

No, because it utilizes fiber-optic technology, the 1756-RMC10 is completely immune to electromagnetic and radio frequency interference, making it ideal for high-voltage industrial environments.

Can this cable be used with any ControlLogix module?

No, it is specifically designed for use with the 1756-RM, 1756-RM2, 1756-RMXT, and 1756-RM2XT redundancy modules.
