GE DS200DSPCH1ADA Digital Signal Processor Control Board

The GE DS200DSPCH1ADA Digital Signal Processor Control Board is a high-speed signal-processing board of the GE Speedtronic™ Mark V DS200 family, used in Mark V turbine control and the LS2100/LS2100e Static Starter control system (now Baker Hughes / GE Vernova). It physically executes master/slave processing logic for the static-start function — firing-angle, current, and commutation control for accelerating a gas turbine generator set — with local high-speed I/O interfaces within the VME-based control rack.

Key Features

• Digital Signal Processor (DSP) control board for Mark V turbine / LS2100 static starter control
• Executes high-speed, real-time signal-processing logic (master/slave processing roles) with local high-speed I/O
• Part of the LS2100 Static Starter control rack, mounted in the VMEbus cabinet (paired with Analog-to-Digital daughterboard DS200ADMAH1A)
• Front panel with 2 pushbuttons, 6 status LEDs, and 4 test points (TP1–TP4) for diagnostics
• Not backwards compatible with earlier DSPC revisions
• Standard DS200 form factor for rack installation

Technical Specifications

• Type Designation: DS200DSPCH1ADA (DS200DSPCH1A board, “DA” revision)
• Functional Acronym: DSPC (Digital Signal Processor Control)
• Instruction Manual: GEI-100220 (GE Industrial Systems)
• System: GE Speedtronic™ Mark V DS200; LS2100 / LS2100e Static Starter Control
• Function: High-speed digital signal processing — static-start drive control logic (firing/current/commutation) and master/slave processing execution
• Processor: DSP-based processing architecture
• I/O Interface: Local high-speed I/O interface on board; VMEbus rack backplane connection
• Companion Boards: Used with DS200ADMAH1A Analog-to-Digital daughterboard (below the DSPC in the VME rack)
• Front Panel: 2 pushbuttons, 6 LEDs, 4 test points (TP1–TP4)
• Backward Compatibility: Not backwards compatible
• Mounting: VME rack slot in the LS2100 / Mark V control cabinet
• Origin: United States

Installation Notes

1. De-energize the LS2100 / Mark V control cabinet before inserting or removing the board.
2. Confirm the board revision against GEI-100220 — the DSPC is not backwards compatible, so match the revision required by the system configuration.
3. Install the DSPC in its designated VME slot; seat the backplane connector fully and secure the board (the ADMAH1A analog-to-digital daughterboard mounts beneath it).
4. On power-up, verify the 6 front-panel LEDs and test points (TP1–TP4) per the instruction manual; confirm static-start control signals are healthy before starting the turbine set.
5. Keep the GEI-100220 manual reference on file for diagnostic and revision checks.

Common Questions

What does the DSPC board do? It performs high-speed digital signal processing for the static-start function: it executes the real-time drive-control logic (firing, current, commutation) that accelerates the gas turbine generator set during starting, and provides local high-speed I/O to the associated boards.

Is the DSPC part of the Mark V or the LS2100? Both — it is a Mark V DS200-series board used in LS2100/LS2100e Static Starter control applications (the static-start drive for turbine sets). AX Control documents it within the LS2100 VME control rack.

Is the DS200DSPCH1ADA interchangeable with other DSPC revisions? No — per GE instruction GEI-100220, the DSPC is not backwards compatible. Match the revision to the system’s documented configuration.

What documentation covers this board? GE instruction manual GEI-100220 (GE Industrial Systems) covers the DS200DSPCH1A DSPC board, including installation, operation, and diagnostics (pushbuttons, LEDs, test points).
