1786-RPFRXL Allen-Bradley ControlNet Module | Single-Mode Fiber

Allen-Bradley 1786-RPFRXL ControlNet Long-Distance Fiber Optic Repeater Module

Product Overview

The 1786-RPFRXL is a specialized high-performance fiber optic repeater module within the Allen-Bradley ControlNet family. Engineered by Rockwell Automation, this module is designed for long-distance signal transmission, effectively bridging gaps that standard copper coaxial media cannot reach. By utilizing fiber optic technology, the 1786-RPFRXL provides absolute immunity to electromagnetic interference (EMI) and radio frequency interference (RFI), making it the ideal solution for large-scale industrial campuses, wastewater treatment facilities, and mining operations. It functions by regenerating and retiming ControlNet digital signals, maintaining deterministic communication across distances up to 20,000 meters (20 km) when using single-mode fiber.

Technical Specifications

The 1786-RPFRXL is a mission-critical component for extending the physical layer of ControlNet networks while maintaining strict timing constraints.
