GE DS3800NECA1B1A
¥999.00The DS3800NECA1B1A is a specific variant of the High-Speed Counter/Accumulator board manufactured by General Electric (GE) for the Mark IV and Mark V Speedtronic turbine control systems. It belongs to the DS3800NECA base series, with the extended suffix 1B1A indicating Revision B, a specific component population, and an A-type conformal coating. The B revision represents a refined iteration over Revision A, and the A coating provides baseline environmental protection.
This 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.
