ABB PCD231 3BHE025541R0101 Control Interface Module

Product Description

ABB PCD231, Part No. 3BHE025541R0101 (also marked PCD231B / PEC80-CCI), is a high-performance converter control interface module for the AC800PEC platform, compatible with UNITROL 6000 excitation systems. It is the core communication control card between the main controller and power converter unit. Equipped with multiple Ethernet ports, optical fiber channels and I/O terminals, it handles high-speed pulse transmission, power unit status acquisition and real-time control data exchange. It supports closed-loop control for multi-axis and high-power power electronic applications, featuring high real-time performance, galvanic isolation and strong anti-interference capability. It is widely used in power plant excitation, high-voltage frequency conversion, SVG and other high-power converter packages.
