GE DS200GGIAG1B
- Part Number: DS200GGIAG1B
Overview: The DS3800HXPD1B1D is a specialized high-speed counter/accumulator board manufactured by GE for Mark IV and Mark V Speedtronic turbine control systems. The "X" in the base model DS3800HXPD denotes a custom or prototype configuration with specialized PLD firmware and component selection for non-standard turbine applications or OEM-specific requirements. The suffix "1B1D" indicates Revision B, a specific component population, and D-type conformal coating. The board conditions and counts pulse signals from magnetic speed pickups or proximity probes, delivering accurate rotational speed data essential for turbine startup sequencing, fuel control, synchronization, and over-speed protection logic.
