The GE DS200PTBAG1A is a P-Core Terminal Board designed for the Mark V Speedtronic turbine control system. It is a critical component of the system’s Triple Modular Redundant (TMR) architecture, serving as the physical interface for field wiring related to the dedicated Protection Core.
Technical Breakdown 🛡️
The board’s function is a cornerstone of the Mark V’s renowned safety and reliability:
- P-Core (Protection Core): In the Mark V TMR system, the “P” core is a separate, dedicated processor focused solely on safety and protection logic. While the R, S, and T cores handle the main control functions, the P-Core continuously and independently monitors critical safety parameters, such as turbine overspeed, to ensure a safe and immediate shutdown if a dangerous condition occurs.
- Terminal Board: This board provides the physical termination points for all the field wiring associated with the P-Core. It uses robust screw terminals to connect sensors, switches, and other devices whose signals are fed directly to the protection logic. This design ensures a reliable and secure connection for safety-critical signals.
- Safety-Critical Role: The DS200PTBAG1A handles signals that are not for routine control but for essential protection functions. For example, a signal from an overspeed trip device would terminate on this board, feeding its signal directly to the P-Core. Its failure would compromise the system’s independent safety layer.
The DS200PTBAG1A is an essential part of the redundant protection system, providing a separate, dedicated physical connection that ensures the P-Core can function independently of the main control processors. This enhances the overall safety and dependability of the turbine control system.
