The 1786-RPFRL is a ControlNet long-distance optical loop repeater module manufactured by Rockwell Automation. It is not a standalone device, but must be inserted into the 1786-RPFM repeater adapter bracket to convert ControlNet electrical signals into optical signals.
Media Conversion & Repeating
Ring Redundancy & Topology
Long-Haul Transmission
The 1786-RPFRL is a high-performance single-mode fiber optic repeater module specifically designed for ControlNet networks (Function). It features a modular plug-in design that operates within a 1786-RPFM adapter base and supports highly reliable ring redundancy topologies (Structure). By extending communication distances to over 20 km and providing superior EMI immunity, this module ensures stable ultra-long-range data transmission while significantly reducing the risk of downtime caused by communication failures, offering exceptional system assurance value.

Oil & Gas
Implementing secure networking between the central control room and remote tank farms in large refineries.
Power & Utilities
Providing EMI-immune data links between substations for remote monitoring and control.
Steel & Metallurgy
Ensuring long-distance transmission of control signals in hot rolling lines with high temperatures and strong magnetic fields.
Railway & Transit
Used in subway tunnel signaling systems for redundant network communication between stations.
Chemical Industry
Using fiber optics in hazardous areas to eliminate the risk of electric arcs from electrical signals.
Pulp & Paper
Connecting distributed I/O across workshops in large paper mills to resolve potential difference issues.
When using the 1786-RPFRL, ensure it is securely locked into the 1786-RPFM base and used exclusively with single-mode fiber, mixing it with multi-mode modules is strictly prohibited. As fiber optic communication is highly sensitive to contamination, cleaning the fiber connectors before installation is essential. Additionally, you must accurately calculate the optical power budget to ensure link attenuation remains within specifications and correctly configure the switches on the base when setting up a ring topology to enable its redundancy features.
The 1786-RPFRL is a ControlNet repeater module, specifically a long-range fiber ring module.
