GE IS200DSPXH1CAA High‑Speed DSP Digital Signal Processor Control Board

Product Description

IS200DSPXH1CAA is a dedicated plug‑in digital signal processor circuit board made by General Electric. It fits for GE Mark‑VI turbine control rack and EX2100 generator excitation control system.

The 60‑MHz onboard DSP chip undertakes high‑speed field‑signal calculation, excitation‑bridge gating control, generator field‑current regulation and fast interrupt response. It communicates 

with other rack‑based boards via the VME‑bus backplane, collects real‑time sensor data and executes closed‑loop control logic. Widely equipped on gas‑turbine, steam‑turbine and generator‑set control 

cabinets inside thermal‑power stations and heavy‑duty power‑generation plants.
