Products Description
GE DS200SDCCG5AHD DC Control Circuit Board
The GE DS200SDCCG5AHD is a dedicated DC control circuit board designed for the GE Mark V Speedtronic turbine control system. It processes direct‑current control signals and implements power loop regulation for turbine excitation and auxiliary drive control.

This plug‑in PCB assembly integrates signal conditioning circuits, fault monitoring loops and multi‑channel backplane connectors. It provides overvoltage and overcurrent detection, and serves as an essential spare part for overhaul and retrofitting of power plant turbine control equipment.
