Description
The GE DS200DSPCH1A / DS200DSPCH1ADA is a Digital Signal Processor Control Board (DSPC) used in GE’s Mark V Speedtronic turbine-control platform. The available technical references identify the DS200DSPCH1ADA as a Mark V DSP control board, rather than a Mark VIe board as stated in the supplied listing.
The board provides high-speed processing and local I/O capabilities for control applications. It includes VME-bus connectivity, onboard memory, front-panel interfaces, status LEDs, test points, and daughterboards for signal conditioning and isolation.

Functional Description
The DSPC board is designed to perform real-time digital processing within GE turbine and industrial drive-control systems. It can function as a master or slave device and has its own memory and local high-speed I/O interfaces.
The DS200DSPCH1ADA version includes daughterboards mounted to the main PCB. These boards provide functions such as signal scaling, buffering, isolation, and conditioning before signals reach the digital signal processor. The board also includes front-panel LEDs, a reset button, test points, and two backplane connectors.
Typical Applications
- GE gas turbine control
- GE steam turbine control
- Industrial turbine drives
- Generator control systems
- GE Mark V Speedtronic systems
- Power-generation plants
- Industrial drive applications
- Legacy turbine-control retrofit projects
Installation & Configuration
- Verify the complete board number: DS200DSPCH1A / DS200DSPCH1ADA.
- Confirm the existing Mark V system configuration.
- Record all board connections before removal.
- Remove system power before replacing the board.
- Inspect the VME/backplane connectors.
- Check the daughterboards and standoffs for physical damage.
- Install the board in the correct rack position.
- Secure the front-panel retaining screws.
- Restore system power.
- Check the six status LEDs.
- Verify VME communication and associated I/O.
- Run the appropriate turbine/drive control diagnostics.
Commissioning Checklist
- Confirm complete part number
- Verify board revision
- Inspect VME connectors
- Check daughterboards
- Verify rack position
- Check status LEDs
- Verify reset function
- Check test points where required
- Verify VME communication
- Confirm local I/O
- Review system diagnostics
- Perform controlled system testing
⚠️ Important Identification Note
The supplied listing calls the item “GE Mark Vie,” but the stronger technical references identify DS200DSPCH1A / DS200DSPCH1ADA as Mark V DS200 hardware. GE’s Mark V product listings specifically include the DS200DSPCH1 and DS200DSPCH1ADA under the Mark V series.
There are also multiple revisions in the DS200DSPCH1 family, including DS200DSPCH1ACA, DS200DSPCH1ADA, and DS200DSPCH1AEA. Do not substitute these solely because the basic DSPC designation is the same; confirm the complete revision and system configuration first.
