Product Introduction

The ABB PCD231B101 3BHE025541R0101 is a core control module for ABB UNITROL generator excitation systems. It provides automatic voltage regulation, signal acquisition, logic processing and bus communication. It samples generator voltage and current signals to adjust excitation output and maintain stable generator terminal voltage, with integrated fault monitoring and protection functions. Widely used in power plant excitation control cabinets.

Content Details

PCD231B101 3BHE025541R0101 is rack-mounted inside the excitation cubicle. It exchanges real-time data with interface boards and power units through internal system bus. It executes AVR and PSS control algorithms and features hardware surge protection against overvoltage and electromagnetic interference. Front LED indicators show module operation status and fault codes for quick on-site diagnosis. High-reliability industrial PCB withstands vibration and heavy EMI in power station environments. It serves as essential spare part for excitation system maintenance and upgrade. Every module passes full function test and thermal aging test before shipment.
