Description

The Allen-Bradley 1756-RMC1 is a 1-meter (3.28 ft) duplex single-mode fiber-optic cable engineered for the ControlLogix 1756 redundancy platform. This cable serves as the high-speed synchronization link between redundant ControlLogix chassis, enabling seamless state and memory cross-loading between the Primary and Secondary controllers. By facilitating deterministic communication between redundancy modules, the 1756-RMC1 ensures high availability and zero-downtime performance in mission-critical automation applications.

Features

  • Optimized for side-by-side chassis configurations with a 1-meter length.
  • Industrial-grade duplex LC connectors for secure, reliable mating with 1756 redundancy modules.
  • Single-mode optical fiber construction providing complete immunity to EMI and RFI.
  • Supports high-speed data synchronization for 1756-RM, 1756-RM2, 1756-RMXT, and 1756-RM2XT modules.
  • Operating wavelength of 1300 nm for stable long-term performance.

Applications

This cable is essential for ControlLogix hot-backup configurations in industries requiring continuous operation, such as oil and gas, power generation, and chemical processing. It connects the redundancy modules to maintain synchronized I/O states and memory, preventing system failure during controller transitions.

Installation Guidelines

  • Ensure the cable is routed through wire ducts to prevent physical damage or excessive tension.
  • Maintain the manufacturer-specified minimum bend radius to prevent signal attenuation or fiber breakage.
  • Inspect LC connectors for dust or debris before insertion; use appropriate fiber cleaning tools if necessary.
  • Avoid excessive force when seating the connectors into the 1756 redundancy module ports.
  • Ensure the cable is secured to prevent accidental disconnection during cabinet maintenance.

FAQ

Is this cable compatible with all ControlLogix redundancy modules?
The 1756-RMC1 is compatible with the 1756-RM, 1756-RM2, 1756-RMXT, and 1756-RM2XT modules.

Can I use this cable in high-EMI environments?
Yes, because the cable uses fiber-optic technology, it is inherently immune to electromagnetic and radio frequency interference, making it ideal for high-voltage industrial panels.
