ABB PCD231B High‑Speed Pulse & Communication I/O Module
Product Brand & Model Title
Official Product Name: PCD231B High‑Speed Pulse & Communication I/O Module Brand: ABB Model No: PCD231B Manufacturer Part Number: 3BHE025541R0101 Product Grade: Legacy high‑speed interface module for AC800PEC platform; end‑of‑production, supplied as spare‑part stock for power generation & medium‑voltage drive systems
General Product Overview
The PCD231B is a high‑speed FPGA‑based pulse processing and communication I/O module for ABB AC 800PEC control platform. It acts as critical signal gateway between main controller unit and power converter hardware. It handles high‑speed pulse signals, encoder feedback, fiber‑optic communication with valve‑base electronics, and digital I/O processing for excitation systems, static frequency converters and medium‑voltage drives. It exchanges real‑time control data with PPD234 main control board via optical fiber, and outputs drive pulses to GDC806 gate drive units. Equipped with multiple status LED indicators for fault diagnosis, it is widely used for generator excitation, ACS6000 medium‑voltage variable‑speed drives and PCS6000 HVDC‑light equipment. Original manufacturing discontinued, mainly used for spare‑part replacement and on‑site retrofit projects.
