Product Details

ABB PCD235A101 3BHE032025R0101 is a high-performance exciter control module for ABB UNITROL generator excitation and AC800PEC control systems. The exciter control module executes core excitation regulation algorithms, collects generator voltage and current signals in real time, and adjusts excitation current to stabilize generator terminal voltage. This ABB PCD235A101 module supports high-speed optical communication to exchange data with I/O boards and controller units, ensuring fast closed-loop response. The generator excitation module integrates multiple protection functions including overexcitation, underexcitation and loss-of-field protection to safeguard generator units from abnormal working conditions. It has built-in self-diagnostic function to continuously monitor module operating status and quickly report fault information. It features excellent anti-electromagnetic interference capability to operate reliably in power plant environments. Widely applied in thermal power, hydropower generation projects, it is an essential spare part for excitation system maintenance and renovation. It adopts rack plug-in structure for simple installation and fast field replacement.
