Product Details

The PCD230A 3BHE022291R0101 is core PEC80‑CCM communication control measurement module for ABB AC800PEC and UNITROL excitation system.

This PCD230A module integrates rich I/O resources and multi‑protocol communication interfaces, it undertakes signal collection and data forwarding tasks inside excitation cabinet.

It can realize seamless data exchange between excitation regulator and upper‑level monitoring system, upload real‑time operating data, working parameters and fault alarm information of generator excitation system.

Multiple communication ports meet diverse on‑site access requirements, dual redundant power supply improves the stability of long‑term operation of power plant equipment.

Front‑panel LED indicators display power status, I/O channel and communication link running condition.

Built‑in complete hardware self‑diagnosis function can detect channel fault, communication abnormality and internal hardware failure, fault information can be uploaded to plant monitoring system.

Industrial‑grade circuit design adapts to complex electromagnetic interference environment of power plant cabinet.

Adopt standard rack installation structure. Widely applied in thermal power, hydropower generator excitation projects.

It is important spare hardware for UNITROL excitation system renovation, communication channel debugging and defective PCD230A module replacement.
