Description
Product Overview
The Allen‑Bradley 1786‑RPFPXLB is a ControlNet single‑mode fiber repeater module for Rockwell automation control networks. It converts electrical ControlNet copper‑cable signals into optical signals for long‑distance transmission over single‑mode fiber cables, and performs reverse optical‑to‑electrical conversion at the receiving end. This device supports ControlNet ring‑redundant topology to improve network anti‑interference capability and system reliability. It requires external 24 VDC power supply and adopts ST‑type fiber connectors. Widely deployed in large‑scale manufacturing, process‑industry sites for legacy ControlNet network reconstruction, expansion and spare‑part replacement.
Series
ControlNet industrial communication series, including repeaters, taps, cables and adapters, providing deterministic real‑time control‑level network for Rockwell‑brand PLC and I/O devices.
Product Features
- Single‑mode fiber repeater for ControlNet network, realizes copper‑to‑fiber signal conversion
- ST‑type fiber optic connector for stable single‑mode fiber connection
- Supports ControlNet ring‑redundant topology, automatic link recovery when single‑fiber link fails
- Greatly extends ControlNet communication transmission distance for cross‑workshop long‑distance networking
- Fiber‑optic transmission effectively isolates ground‑loop interference and electromagnetic noise in heavy‑EMI industrial environments
- External 24 VDC DC power supply, independent power supply design
- LED indicator lights for power, network link and fault status for quick‑on‑site diagnosis
- Compatible with standard ControlNet communication protocol, no extra protocol configuration required
