GE DS200DCFBG1BLC Mark V DC Feedback Board

GE DS200DCFBG1BLC is a DC feedback signal processing board designed for GE Mark V turbine control system. It collects and conditions multiple DC analog feedback signals from field equipment, converts them into standard digital signals and transmits data to main controller for turbine closed‑loop regulation and status judgment.

This PCB board is installed inside Mark V control rack, equipped with signal conditioning circuit and fault detection function. It adopts standard rack‑mounted structure, widely used as replacement spare parts for power plant steam turbine and gas turbine control cabinet maintenance and retrofit projects.
