Product Introduction

The ABB PCD235A101 3BHE032025R0101 is a high-performance exciter control module based on AC800PEC hardware for ABB UNITROL generator excitation systems. It implements automatic voltage regulation (AVR), power system stabilizer (PSS), signal sampling, logic control and internal bus communication. It collects generator voltage and current signals, calculates excitation control outputs to stabilize terminal voltage, and supports comprehensive fault monitoring and protection functions. Widely used in thermal and hydro power plant excitation cabinets.

Content Details

PCD235A101 3BHE032025R0101 adopts rack mounting inside excitation control cubicle. It connects with other interface boards and power units via internal bus, executes excitation regulation algorithms and handles I/O signal processing. Built-in hardware protection protects the module from surge voltage and electromagnetic interference. Front panel LED indicators display module running status and fault codes for fast on-site troubleshooting. Rugged industrial hardware can endure vibration and harsh electromagnetic environment in power stations. It is a critical spare part for generator excitation system maintenance and retrofit. Each unit passes full function test and thermal aging test before shipment.
