Overview
The ABB RMU811 Symphony Plus Repeater is not a standalone repeater module but a mounting base designed to host two RFO810 modules in a redundant configuration. It plays a vital role in extending the HN800 bus communication over fiber optics, enabling long-distance and EMI-resistant data transmission in distributed control systems.
Moreover, RMU811 simplifies installation by integrating power distribution and HN800 connectors directly into the base. This ensures clean wiring, reliable signal routing, and easy maintenance. In addition, its compact form factor and DIN rail compatibility make it ideal for control cabinets in power generation, water treatment, and process automation facilities.
For instance, in a Symphony Plus system, RMU811 allows SD Series controllers to communicate with remote I/O racks up to 3 km away using RFO810 repeaters. Therefore, it’s essential for scalable and fault-tolerant network architecture.
