Energy Storage	220 µF at 35V

GE DS200UCVAG1A DS200UCVAG1ABB stores energy using two electrolytic capacitors. Together, they provide 220 µF at 35V rating for output hold-up. This energy storage maintains digital outputs during 25 millisecond power interruptions. Therefore, the board prevents false switching in turbine control environments.

Design and Integration

Both the GE DS200UCVAG1A and DS200UCVAG1ABB versions share identical I/O circuitry. These boards use six-layer PCB construction with isolated I/O banks for noise immunity. Consequently, the GE DS200UCVAG1A DS200UCVAG1ABB operates reliably from -15°C to +60°C ambient temperature.

For installation, you need M3 screws for the four mounting holes. The board draws 350 mA typical current from the 24V DC supply. Each analog input includes software selectable filtering. We recommend using shielded cables for all analog field connections.

Practical Application

This Mark V board connects field sensors and actuators to a turbine controller. It reads speed probes, thermocouples, and pressure transmitters continuously. The GE DS200UCVAG1A DS200UCVAG1ABB then sends output commands to servo valves and trip solenoids. Therefore, it serves as a primary I/O interface for GE Mark V turbine control systems.
