Product Details

The UAC389AE02 HIEE300888R0002 is core Network Communication Processor for ABB Symphony INFI90 DCS platform, it acts as important INFI‑NET Ring Interface Board.

This module undertakes core tasks such as real‑time process data transmission on INFI‑NET ring network, control logic operation and I/O module management. It adopts redundant ring network design, when single‑point network fault occurs, it can realize automatic link switching to avoid network paralysis. Hot‑swap function supports online replacement without shutting down the whole system, reduce equipment maintenance downtime.

Front‑panel LED indicators display power status, ring network running status, data transceiver and fault alarm information. Built‑in complete self‑diagnosis function can detect ring network abnormality, communication interruption and internal hardware failure, fault information can be uploaded to upper monitoring station. Industrial‑grade circuit design adapts to harsh working conditions of power plant control cabinet.

Standard rack plug‑in structure, convenient for installation and maintenance. Widely applied in thermal power, petrochemical, pulp‑paper industries. It is key spare hardware for INFI90 system transformation, ring network fault maintenance and defective UAC389AE02 module replacement.
