GE DS200DCFBG1BNC Mark V DC Feedback Board

GE DS200DCFBG1BNC is a DC feedback signal conditioning board for GE Mark V gas and steam turbine control system. It receives multi‑channel DC analog signals from field transmitters and sensors, performs filtering and signal conditioning, and converts analog quantities into digital data for main controller closed‑loop calculation.

This circuit board is installed in Mark V standard rack slot, compatible with Mark V control hardware platform. It owns built‑in fault detection mechanism for signal channel and hardware circuit. Widely used as replacement spare parts for power plant turbine control cabinet maintenance and system retrofit projects.
