IS200EDEXG1BAA

Description

IS200EDEXG1BAA is a GE Exciter De-Excitation Control Board for the EX2100e excitation system.

SCR Firing Control

• Function: Controls Silicon Controlled Rectifiers to manage and dissipate generator field energy during emergency shutdowns.

Conduction Feedback

• Monitoring: Provides real-time feedback on SCR conduction to ensure smooth and efficient de-excitation.

Voltage Retention

• Capability: Maintains voltage in the excitation system even during power interruptions.

System Integration

• EMIO Coordination: De-excitation is initiated by the EMIO board.

• EXTB Interaction: Signals transferred from auxiliary contacts to SCR firing circuits for proper energy dissipation.
