Signal Routing & Feedback
The IS200GGXDG1ABB receives high-frequency voltage input from the GDPA Gate Driver Power Assembly. It transmits gating commands and status signals via RS-422 and fiber-optic links. The board sends three current feedback signals, a GDPA power OK signal, and a continuity check for the NATO Voltage Feedback Attenuator Board.
Power & Monitoring Features
Onboard regulated power supplies support communication and monitoring circuits. The board includes seven grounding connectors for selective isolation and multiple test points for diagnostics. LED indicators provide visual status of key functions.
Application & Compatibility
This board is ideal for GE Mark VI systems using dynamic braking or diode source configurations. The IS200GGXDG1ABB ensures reliable signal transmission and system protection in high-voltage environments. It integrates seamlessly with BICI, GDPA, and NATO modules.
