DS200FCGDH1BBA Functional Description   

The DSP Drive Control DS200FCGDH1BBA General Electric is a Gate Distribution and Status Board from the LCI series, designed to support 6-pulse phase-controlled non-reversing bridge configurations. Measuring 9.2 by 6.3 inches and built to the 6U VME standard, this board ensures compatibility with common VME racks used in industrial automation. Featuring a six-layer design with surface-mounted devices on both sides, the General Electric DS200FCGDH1BBA offers durability and reliability needed for demanding environments.

Functionally, the General Electric DS200FCGDH1BBA Gate Distribution and Status Board acts as a key interface between the control system and bridge components. It decodes firing signals, distributes gate signals, and collects feedback and diagnostic data to enable precise control of the power bridge. The board is mounted alongside the Digital Signal Processing Card (DSPC) in the same VME rack, which allows centralized control and optimizes system performance.

The PC Control Module Board Mark V DS200FCGDH1B also includes current feedback circuits that process signals from current transformers or LEM® modules on the power bridge. These signals are conditioned and converted into IA, IB, and IC phase currents and fed into voltage-controlled oscillator (VCO) circuits to regulate switching frequency and ensure stable operation. The Control Module General Electric DS200FCGDH1BBA features testpoints for easy monitoring of these signals.

Overcurrent protection is a critical feature of the DS200FCGDH1BBA GE Speedtronic Turbine Controller. It monitors combined current signals and triggers protection if excessive current persists beyond a preset threshold. This protection requires a hardware reset to clear, ensuring system safety. Visual indicators on the board provide real-time feedback, helping operators maintain safe and efficient operation.
