Product Introduction

The ABB PCD231B 3BHE025541R0101 is the main control module of ABB UNITROL generator excitation system. It realizes automatic voltage regulation, power system stabilization, multi-channel signal sampling, logic operation and internal bus communication. It collects generator voltage and current signals to adjust excitation output for stable terminal voltage, and comes with fault monitoring and protection functions. Widely applied in power plant excitation cabinets.

Content Details

PCD231B 3BHE025541R0101 adopts rack installation inside excitation cubicle. It communicates with peripheral interface boards and power units via internal bus, running AVR and PSS control algorithms. Built-in hardware protection defends against overvoltage and electromagnetic surge interference. LED indicators on front panel display module running status and fault codes to support fast on-site troubleshooting. High reliability industrial hardware adapts to vibration and strong EMI environment of power stations. It is critical spare part for excitation system maintenance and retrofit. Each module passes full function test and thermal aging test before shipment.
