GE IS200DSPXH1D Key features
Controls gating logic, field-voltage/current regulation, bridge firing
Error handling via stack overflow, watchdog timers, inner-loop interrupts
Emulator (P5) and monitor (P6) ports support in-field diagnostics
No status LEDs—fault info via host controller diagnostics
Conformal-coated PCB suits harsh industrial environments
OPERATION:
Board executes DSP control loops, handles interrupts for torque and gate logic, manages watchdog and stack overflow protection, and communicates status via backplane to host control system.


Performance comparison
Parameter | IS200DSPXH1C | IS200DSPXH1D | IS200DSPXH2D |
Analog I/O Channels | 12 | 12 | 6 |
Board Coating | Standard | Conformal-coated | Conformal-coated |
Status LEDs | 2 LEDs | None | 2 LEDs |
Protection | Watchdog, overflow | + reset enhancements | Same as H1C |
Summary:
DSPXH1D shares core 60 MHz DSP and I/O capabilities with H1A/C boards, but adds conformal coating and resets enhancements. It omits LEDs but retains full diagnostic port access.
Typical cooperation cases
Europe – Gas Turbine Control
Used in Mark VI racks to manage gate control and diagnostic interfaces.
Asia – EX2100 Excitation Systems
Supports bridge firing and field regulation logic in excitation control cabinets.
North America – Retrofit Projects
Replaces older DSP boards in EX2100 drives with firmware-compatible, rugged modules.
