GE DS200FCGDH1ABA Gate Distribution and Status Card

Overview

The GE DS200FCGDH1ABA is a Gate Distribution and Status Card for LCI systems. It interfaces the control system with a 6-pulse non-reversing SCR bridge. The board distributes firing commands from the DS200DSPC processor to the SCRs. It collects bridge diagnostics and feedback signals, ensuring safe turbine operation. Real-time monitoring of voltage, current, and frequency keeps the system reliable. This card is essential for precise SCR synchronization in gas and steam turbines.
