Description
Product Overview
The IS200EHPAG1DAB Exciter Gate Pulse Amplifier Board from GE is a critical interface between the controller and the Power Bridge in EX2100 excitation systems. It receives gate commands from the ESEL board and generates firing pulses for six SCRs. The board also handles conduction feedback, airflow monitoring, and temperature sensing.

Monitoring & Protection Features
The IS200EHPAG1DAB supports RTD-based temperature monitoring and legacy Klixon switch configurations. It triggers alarms at 76 °C and trips at 87 °C. Fan rotation switches detect airflow across the bridge, ensuring proper cooling and fault isolation.
Signal Interface & Control
This board connects directly to the ESEL for gate command input and distributes signals to SCRs. It integrates seamlessly with retrofit and new exciter systems, offering flexible feedback options and robust fault detection.
Application & Compatibility
The IS200EHPAG1DAB is ideal for turbine control systems requiring precise SCR gate control and environmental monitoring. It supports both new installations and retrofits, ensuring compatibility with existing bridge configurations.
