GE IS200DSPXH1DBD DSP Digital Signal Processor Board

GE IS200DSPXH1DBD is a high-performance DSP digital signal processor control board for GE Mark VI turbine control and EX2100 generator excitation system. It adopts a 60MHz DSP chip to run excitation closed-loop control algorithms, complete high-speed sampling of generator PT/CT signals and implement bridge rectifier gating control.

This board is equipped with Flash, DRAM and NVRAM memory to store control parameters and fault records. It communicates with other rack modules through VME backplane bus, with front panel LED indicators for status and fault alarms. It serves as critical spare parts for power plant turbine and excitation cabinet overhaul.
