The GE DS200SDCCG5A is a Main Control Card that acts as the central processing unit (CPU) for a variety of GE control systems, including the Mark V Speedtronic turbine control system and the EX2000 Excitation System. This board is the “brain” of the system, responsible for executing all control algorithms and logic in real-time. The G5A in the part number indicates a specific hardware revision.
Technical Breakdown 💡
The card’s function is the foundation of the system’s performance and reliability:
- Central Processor: The DS200SDCCG5A is equipped with three microprocessors and dual-ported RAM. These processors work together to manage the industrial process, whether it’s regulating a generator’s output, controlling a motor’s speed, or providing critical safety functions like emergency overspeed protection and NOx detection. It processes a continuous stream of feedback signals and uses this data to make split-second decisions to maintain stability and performance.
- SDCC Designation: The “SDCC” stands for Static Drive Control Card, highlighting its primary role in controlling static power converters, which are used to control the speed and torque of large motors or to regulate the voltage of generators.
- System Integration: As the main control card, it communicates with all other modules in the system, including I/O cards, power supplies, and communication boards. It is the central component that orchestrates the entire system’s operation. The card includes five EPROM connectors, with four for factory-programmed parameters and one for user-configured settings, allowing for flexible application customization.
This single board is responsible for orchestrating the entire control system, ensuring the performance and protecting the connected machinery from operational stresses.
