Description

The DS200ADGIH1AAA is a specialized Auxiliary DC Generator Interlock and Control Card designed for the GE EX2000 excitation control series. This module plays a critical role in gas turbine excitation systems by managing interlock sequences and control logic for high-voltage auxiliary DC systems. It serves as a vital interface between the Turbine Control System (TCS) and the Generator Control Panels (GCP), ensuring reliable synchronization and protection during turbine startup, operation, and shutdown sequences.

Features

• Designed for integration within the GE EX2000 excitation rack architecture.
• Processes auxiliary signals for high-voltage DC system monitoring and control.
• Supports robust analog output for real-time system feedback.
• Engineered for high signal integrity in electromagnetically noisy turbine hall environments.
• Facilitates critical interlock logic to prevent generator system faults.

Applications

This control card is primarily deployed in power generation facilities and heavy industrial turbine units utilizing GE EX2000 static excitation systems or brushless exciters. It is essential for maintaining operational stability and protecting generator assets from transient faults.
