System Role & Functional Behavior
The DS200SHVMG1AFE acts as a high-voltage signal processing and interface hub:
- Converts shunt signals (-500 mV to +500 mV) into digital frequency outputs
- Provides isolation between SCR bridge and control electronics
- Interfaces with power supply boards (DCFB / SDCI) and PCCA cards
- Supports AC current attenuation via 10:1 CT configuration
- Enables configurable signal scaling using onboard jumpers
- Ensures safe transmission of high-voltage measurement signals
It functions as a critical translation layer between power conversion hardware and turbine control logic.
