RFO810 ABB HN800/cW800 Fiber Optic Repeater Module

Product Description

The ABB RFO810 is a high-performance, redundant optical communication repeater designed to extend the reach of industrial control networks. Specifically engineered for the Symphony Plus (S+) Control system, this module allows SD Series controllers (such as the HPC800 and SPC700) and HR Series controllers (including BRC300/400/410) to communicate transparently with remote I/O devices.

By converting electrical signals to fiber optics, the RFO810 bypasses the distance limitations of standard copper cabling, extending the HN800 or CW800 bus up to 3 km. This makes it an essential component for distributed architectures where controllers and I/O clusters are separated across large industrial sites. The module supports robust "Star Architecture" configurations, providing the scalability and fault tolerance required for mission-critical power and water utility applications.

Application Scenarios

The RFO810 is frequently deployed in large-scale infrastructure projects, including:

• Power Plant Automation: Connecting the main control room to remote turbine or boiler I/O racks located in separate buildings.

• Water Treatment Facilities: Extending peer-to-peer communication between controllers across expansive filtration and pump stations.

• Large Industrial Campuses: Linking distributed process areas into a single, cohesive Symphony Plus control network without signal degradation.
