System Role & Functional Behavior
The DS200SHVIG1BGD acts as a high-voltage signal translation and protection interface:
- Converts SCR shunt signals (-500 mV to +500 mV) into frequency signals (0–500 kHz)
- Interfaces SCR bridge with PCCA and power supply boards
- Provides electrical isolation between high-power and control circuits
- Supports configurable attenuation via 17 jumpers
- Enables accurate monitoring of SCR-based power conversion
- Assists fault detection via onboard LED indicators
It functions as a critical data bridge between high-energy power electronics and turbine control logic.
