The GE DS200TBPAG1A is a PLU Terminal Board for the Mark V Speedtronic turbine control system. It provides the physical interface for all field wiring connected to the system’s Primary Logic Unit (PLU).
Technical Breakdown 🧠
This board is a key component in a specific configuration of the Mark V system, providing a reliable connection for all input and output signals.
- PLU Architecture: Unlike the more common Triple Modular Redundant (TMR) architecture that uses three redundant processors (R, S, and T), some Mark V systems utilize a simpler, single-processor design known as the Primary Logic Unit (PLU). This configuration is often found in applications where TMR redundancy is not a requirement, such as for smaller turbines or less critical processes. The DS200TBPAG1A is the dedicated terminal board for this specific PLU processor.
- Terminal Board Function: The board provides a comprehensive set of robust screw terminals for a wide range of field signals, including analog inputs (e.g., from pressure and temperature sensors), digital inputs, and digital outputs. It serves as the single point of connection for the controller’s main I/O.
- System Context: The DS200TBPAG1A ensures that all operational and safety-related signals from the turbine are accurately and reliably fed to the single PLU processor. Its design ensures a solid physical connection that minimizes the risk of signal loss or interference, which is critical for the system’s stability.
In essence, the DS200TBPAG1A is the foundational physical interface that enables the single-processor Mark V PLU system to effectively monitor and control a turbine’s operations.
