GE DS200SDCCG1AEC DS215SDCCG1AZZ01A Servo Drive Control Board

The GE DS200SDCCG1AEC with assembly number DS215SDCCG1AZZ01A is a servo drive control board for GE Speedtronic Mark V turbine control systems. It processes servo position feedback signals and outputs drive commands for valve servo actuators, governing fuel valves and steam‑valve positioning for gas and steam turbine units.

This rack‑mount conformal‑coated PCB integrates signal conditioning circuits, position feedback channels and diagnostic LED indicators. It implements closed‑loop position regulation for turbine servo loops. It serves as essential aftermarket spare for maintenance, overhaul and retrofitting of power‑plant turbine control cabinets.
