Product Details

The UAC326AE01 HIEE401481R1 is reliable Serial Gateway Module for ABB Advant OCS DCS platform, it acts as core Advant OCS Communication Unit for serial protocol conversion.

This module is installed in Advant OCS system rack, equipped with RS‑232 and RS‑485 serial interfaces. It supports Modbus RTU and AF100 bus pass‑through function, realizes data interaction between DCS main processor and third‑party intelligent field instruments. Built‑in galvanic isolation and multi‑stage filter circuit effectively suppress on‑site electromagnetic interference, guarantee stable millisecond‑level data refresh rate.

Front‑panel LED indicators display power status, sending and receiving data and link fault condition. Built‑in hardware self‑diagnosis can detect serial port abnormality, bus communication failure and internal hardware fault, fault signals can be uploaded to upper monitoring system. Compact single‑slot design saves cabinet installation space.

Widely applied in thermal power, hydropower, metallurgy and pulp‑paper industries. It is key spare hardware for Advant OCS system renovation, third‑party instrument access and defective UAC326AE01 module replacement.
