Features:
- Routes six selected gate commands to separate SCR firing channels.
- Returns bridge-conduction and cooling-status signals to the control.
- Uses independent thermal contacts for alarm and trip thresholds.
IS200EGPAG1B serves as the local firing interface inside an EX2100 power conversion module.
Its G1 bridge assignment covers assemblies using 77 mm or smaller thyristors.
A single IS200EGPAG1B is associated with each power conversion module, keeping pulse generation and bridge status tied to the same hardware section.
The General Electric IS200EGPAG1B Exciter Gate Pulse Amplifier Board is supported by Apter Power with quotation and technical assistance.

Command-to-Firing Flow
- Input Command: Logic-level gate requests arrive from ESEL
- Channel Count: Six independent firing outputs are provided
- Load Side: Each output connects to one SCR gate path
- Local Function: The selected commands are amplified beside the bridge
Returned Operating Signals
- Conduction Status: Current-conduction feedback returns from the bridge interface
- Cooling Input: An airflow-detector status is accepted
- Temperature Input: Heat-sink switch states are monitored
- Control Return: Operating conditions travel back with the firing-interface status
Two-Stage Temperature Logic
- Alarm Point: One thermal contact opens at 76 °C
- Trip Point: Both thermal contacts open at 87 °C
- First Stage: The initial switch state generates an overtemperature alarm
- Second Stage: The combined state produces a fault and trip response
Conversion-Cabinet Interface
- Supply Path: Nominal 125 V dc is distributed through EPDM
- Physical Location: The board is installed in the power-conversion cabinet
- Module Allocation: One EGPA board is assigned to each power conversion module
- Control Connection: Cabling links the board to ESEL in the control section
