Information

Overview Manuals Usage Environment Primary Applications

Features:

  • Fiber ring long distance repeater
  • This module Designed for robust industrial applications
  • It operates effectively on a supply voltage of 24 VDC
The Allen Bradley 1786-RPFRL is a long-distance fiber optic ring repeater designed for industrial environments. It operates on 24VDC and meets standard electrical requirements. Its IP20 protection rating makes it suitable for indoor applications, effectively preventing water and dust intrusion.

This device boasts extremely low power consumption, at only 2.8 watts, making it energy-efficient. It features control indicators that display power status and the status of Channel 1 and Channel 2, facilitating real-time monitoring and diagnostics. A 50V isolation voltage provides electrical fault protection.

The 1786-RPFRL Allen Bradley ControlNet Fiber Ring Long Distance Repeater may still be available for purchase and support from Moore Automated Company beyond End-Of-Life (EOL) by the manufacturer (OEM).
Allen Bradley 1786-RPFRL ControlNet Fiber Ring Long Distance Repeater manual(Datasheets), Link Important Notice: Other accessories, manuals, cables, calibration data, software, etc. are not included with this equipment unless listed in the above stock item description. All prices are shown in USD.
The 1786-RPFRL operates optimally in temperatures ranging from 0 to 60 degrees Celsius, making it suitable for various environments. Its relay ports conform to Category 2 cabling standards and are compatible with wire gauges from 22 to 14 AWG, offering flexibility for diverse installation needs. Furthermore, this repeater can operate reliably in relative humidity ranges from 5% to 95% without condensation. This repeater is ideal for effectively extending communication distances in high-efficiency operating environments.
  • Media Redundancy (Ring Topology): Its most critical application is building redundant fiber optic rings. If one fiber optic link between repeaters fails, the system automatically uses another link to maintain communication without interrupting production.
  • Long-Distance Network Extension: It supports communication links up to 3,000 meters (3 kilometers), enabling controllers to connect to remote I/O enclosures in large facilities.
  • High Electromagnetic Interference/RF Interference Environments: Suitable for areas with strong electromagnetic noise, such as near large motors, welding machines, or power lines, the electromagnetic interference immunity of fiber optics ensures stable data transmission.
  • Grounding Isolation: Used to provide complete electrical isolation between different parts of a plant, preventing ground loops and protecting sensitive PLC equipment from power surges.
PRODUCT & ORDER FAQS

Questions buyers ask about 1786-RPFRL

  • What is the main function of the 1786-RPFRL in a ControlNet redundant fiber optic communication architecture?

    The 1786-RPFRL is a redundant fiber optic repeater module designed to extend and enhance ControlNet network segments while maintaining deterministic, high-integrity communication in industrial automation systems.
  • How does the 1786-RPFRL improve network availability in mission-critical industrial control systems?

    The 1786-RPFRL implements redundant fiber optic signal paths, ensuring data transmission continuity even if a single channel fails, thereby maximizing network availability and fault tolerance.
  • Why is the 1786-RPFRL crucial for long-distance signal transmission in ControlNet?

    The 1786-RPFRL can regenerate and retransmit optical signals, enabling longer communication distances beyond standard network segment limitations while maintaining signal integrity and time determinism.
  • How does the 1786-RPFRL maintain deterministic communication behavior in real-time control environments?

    1786-RPFRL maintains ControlNet's scheduled traffic architecture by precisely repeating and synchronizing network frames, avoiding time jitter or protocol distortion.
  • How does 1786-RPFRL support network redundancy and fault-tolerant design strategies?

    1786-RPFRL employs a dual-channel redundancy design, enabling automatic path switching and continuous operation in the event of fiber breakage or module failure.
