Product Details

ABB PCD231B 3BHE025541R0101 is an excitation controller module used in ABB UNITROL generator excitation systems. The excitation controller module is responsible for real-time sampling of generator voltage and current signals, operating voltage closed-loop regulation and system protection logic. This ABB PCD231B module adopts high-speed optical communication to transmit data with peripheral I/O boards, ensuring fast response of excitation control. The generator control module integrates multiple protection functions such as overexcitation, underexcitation and loss of field protection to protect the generator unit. It has built-in self-diagnostic function to continuously check the running status and output fault alarm information. It features strong anti-electromagnetic interference ability and can run stably in harsh power plant environments. Widely used in thermal power, hydropower generator excitation cabinets, it is a key spare part for system maintenance and upgrade. It adopts rack plug-in design for convenient installation and quick on-site replacement.
