GE DS200SDCCG4A Synchronization & Discrete Control Card – Mark VI Turbine Control System
When a synchronization and discrete control card fails mid-operation in a gas or steam turbine plant, the consequences are immediate and severe: unplanned shutdowns, loss of grid synchronization, and costly emergency maintenance windows that can stretch into days. The GE DS200SDCCG4A is the critical interface that prevents exactly this scenario — managing discrete I/O signals, synchronization logic, and protective relay coordination within the Mark VI turbine control architecture. Without it, the entire turbine control loop is blind.
The DS200SDCCG4A occupies a pivotal role within GE’s Mark VI Speedtronic™ turbine control platform — one of the most widely deployed turbine management systems in global power generation. Designed for high-reliability environments, this card handles synchronization sequencing and discrete signal conditioning that are fundamental to safe turbine start-up, load transfer, and shutdown procedures. It is trusted by power utilities, petrochemical plants, and industrial co-generation facilities across six continents.
