Fiber Repeater Module RFO810 ABB Unit for High-Speed Data Transmission Digital Signal Processor Control Board Output/Internal Logic: 1500 V ACOverview 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
