Product Introduction
In a UNITROL 6000 or PEC80-based excitation system the link between the high-level controller and the thyristor converter must be both fast and deterministic. The ABB PCD231B101 (3BHE025541R0101) acts as that Converter Control Interface, providing the specialized measurement, gate-drive and protection I/O required to regulate the bridge while exchanging data over Ethernet, CAN and optical links.
Engineers specify this module when a spare or replacement is needed for an existing PEC80-CCI position; its integrated 3-phase voltage and current sensing, KTY temperature channels and dedicated pulse-blocking input keep the excitation loop intact without additional external signal conditioners.
