GE DS200UCPBG6AFB Universal Control Processor Board

The GE DS200UCPBG6AFB is a universal control processor (UCPB) I/O engine CPU board for GE Speedtronic Mark V turbine control systems. It serves as core processing unit for real‑time turbine control logic, executing governing algorithms, sequence control and interlock protection functions. Installed inside Mark V control rack, it exchanges high‑speed I/O data with other system boards via COREBUS backplane bus for gas‑steam turbine generator‑set control in power‑generation plants.

This processor board is equipped with onboard memory modules, PROM firmware storage, multiple communication interfaces and configurable DIP‑switch hardware settings. It supports ARCNET, RS‑232 serial communication for local HMI and remote SCADA connection. Built‑in self‑diagnostic circuits and LED indicators monitor hardware operating status. Original production has been discontinued. It is widely supplied as aftermarket spare parts for Mark V turbine cabinet maintenance and legacy power‑plant control‑system retrofit projects.

FAQ

1. Q:Can DS200UCPBG6AFB run as standalone controller?
   A:It must be installed inside Mark V rack and cooperate with matched I/O and communication boards, standalone operation is not supported.
2. Q:What symptoms occur upon processor‑board failure?
   A:Turbine control‑logic abnormality, loss of I/O data, ARCNET / serial communication breakdown, system CPU‑fault alarm may appear.

3. Q:How to complete configuration and diagnosis?
   A:Hardware DIP‑switch setup on board, and logic download, fault log reading are completed through GE Mark V official configuration software.
