The GE DS200SHVIG1BFC is a High Voltage Interface Board used in GE Mark V Speedtronic and EX2000-based turbine control systems. It is designed to interface between the SCR bridge circuit and key control/power modules such as power supply boards, instrumentation cards, and the Power Connect Card (PCCA).
Its primary function is to convert, isolate, and transmit high-voltage and shunt-related signals, ensuring accurate measurement and stable control of turbine drive systems under high electrical stress conditions.

System Role & Functional Behavior
The DS200SHVIG1BFC acts as a critical high-voltage signal translation layer inside turbine drive systems:
- Accepts low-level shunt signals from SCR bridge (-500 mV to +500 mV)
- Converts signals into frequency-based outputs (0–500 kHz)
- Transfers processed signals to PCCA, DCFB, or SDCI boards
- Provides electrical isolation between power and control circuits
- Uses jumper configuration for fine-tuned signal attenuation
- Enables accurate monitoring of high-power SCR operations
In practice, it ensures that high-energy power electronics can be safely interpreted by sensitive control systems.
