GE DS200UCPBG5A DS200UCPBG5ADA stores energy using two electrolytic capacitors. Together, they provide 330 µF at 35V rating for output hold-up. This energy storage maintains digital outputs during 30 millisecond power interruptions. Therefore, the board prevents false switching in turbine control environments.
Design and Integration
Both the GE DS200UCPBG5A and DS200UCPBG5ADA versions share identical I/O circuitry. These boards use six-layer PCB construction with isolated I/O banks for noise immunity. Consequently, the GE DS200UCPBG5A DS200UCPBG5ADA operates reliably from -15°C to +60°C ambient temperature.
For installation, you need M4 screws for the four mounting holes. The board draws 400 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 turbine I/O board connects field sensors and actuators to a turbine controller. It reads speed probes, thermocouples, and pressure transmitters continuously. The GE DS200UCPBG5A DS200UCPBG5ADA then sends output commands to servo valves and trip solenoids. Therefore, it serves as the primary I/O interface for GE turbine control systems.
