Features:
- Hardwired Ground Fault Detection
- On-Board Potentiometer Calibration
- Mark IV Exclusive Compatibility
The General Electric DS3800NGDD1C1B continuously monitors field excitation circuits using dedicated hardwired signal paths. This 1980s-era logic design ensures reliable fault detection without dependency on network communication protocols, providing a deterministic response to ground fault conditions in GE Mark IV turbine systems.
The General Electric DS3800NGDD1C1B features field-adjustable potentiometers that allow technicians to calibrate ground fault sensitivity levels precisely. This onboard adjustment capability enables customization to specific site wiring conditions without removing the card from the system rack, simplifying maintenance procedures.
Engineered specifically for GE‘s Mark IV Speedtronic systems, the General Electric DS3800NGDD1C1B is not guaranteed to function in Mark V, Mark VI, or other control platforms. As a Field-Replaceable Unit (FRU), it integrates directly with the Mark IV backplane via edge connectors, ensuring proper signal routing and power distribution within original GE turbine control architectures.
The DS3800NGDD1C1B General Electric Field Ground Detector Card may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).
