Overview

The ABB RFO810 Fiber Optic Repeater Module is designed for industrial control systems requiring long-distance, high-speed communication. It functions as a redundant optical repeater, allowing SD Series controllers (e.g., HPC800, SPC700) and HR Series controllers (e.g., BRC300/400/410) to extend their reach to remote I/O devices via the HN800 bus.

The RFO810 supports a star topology, enabling flexible network design and fault-tolerant communication. For proper operation, it requires HBX01L and HBX01R bus terminators and ensures transparent data transmission without protocol conversion.

Its compact form factor and DIN rail mounting make installation easy in control cabinets. The RFO810 is ideal for applications where electromagnetic interference (EMI) or physical distance limits traditional copper-based communication.

Technical Data

Typical Applications

• Remote I/O Expansion: Extends controller communication to distant field devices in large facilities.

• Substation Automation: Enables fiber-based connectivity in high-voltage environments.

• Process Control Systems: Supports long-distance communication in chemical and manufacturing plants.

• EMI-Prone Installations: Replaces copper wiring to avoid signal degradation from electrical noise.

• Redundant Network Architectures: Provides fault-tolerant links for mission-critical control systems.

Example: In a power plant, the RFO810 allows SD Series controllers to communicate with remote I/O racks over fiber, maintaining signal integrity and system uptime. It is a key component in scalable and reliable automation networks.
