ABB RFO810｜Redundant Optical Communication Repeater｜

• Key Features

  Extended Communication Distance

  Supports long-distance communication up to 3 km over HN800 or CW800 buses.

  HN800 bus supports star topology. When the controller is located at the center of the star:

  Up to 4 RFO810 fiber-optic links are supported.

  Each remote fiber link can extend up to 3 km.

  Each local electrical HN800 bus can connect up to 64 HN800 devices.

  CW800 bus supports one RFO810 fiber-optic link per bus, allowing multiple controllers on both sides of the link, with a maximum distance of 3 km.

  Multi-Protocol Support

  Compatible with multiple communication protocols and cable standards, including:

  FDDI

  Fast Ethernet

  Ethernet

  Token Ring

  High Reliability Design

  Redundant architecture with redundant power inputs to enhance system reliability and availability.

  Equipped with conformal coating, providing improved resistance to moisture, dust, and harsh industrial environments.
