Description
Product Description: GE DS200FCGDH1B Gate Distribution and Status Card
The GE DS200FCGDH1Bis a high-performance gate distribution and status card designed for industrial automation, specifically within GE’s Mark V/VI series of turbine control systems. As a critical component in gas and steam turbine applications, the DS200FCGDH1B manages signal distribution, status monitoring, and fault protection for 6-pulse phase-controlled bridges. It interfaces with the Digital Signal Processing Card (DSPC) via the VME backplane, decoding SCR firing data and distributing cell gating signals to bridge legs. The card also processes feedback signals (voltage, current, frequency) and communicates diagnostic data to the control system. Its modular design, rugged construction, and advanced microprocessor technology ensure reliable operation in harsh industrial environments, making it essential for precision control in power generation, oil and gas, and manufacturing.
