Product Description
Full product name: GE EX2100e Excitation System PCM Processor Control Module, part of the GE 151X series, serves as the core control card for the GE EX2100/EX2100e synchronous generator excitation control system. Featuring a modular plug-in backplane architecture, it integrates high-speed computing chips, multiple network interfaces, and analog signal acquisition circuits, providing full functionality including excitation regulation, logic control, communication, and fault diagnosis. It is the central control unit for excitation systems in thermal and hydroelectric power generation units, compatible with GE gas turbine control hardware platforms. Originally manufactured by U.S.-based GE, this module is a component of the FANUC-GE industrial automation product line.
