GE DS200TBQDG1A MKV,TERM BD (R-S-T) EXT

 

This board is foundational to expanding the I/O capacity of a Mark V TMR system while maintaining fault tolerance.

  • TMR Architecture (R-S-T): The Mark V system uses three identical processors—R, S, and T—that simultaneously execute the same control software. This board ensures that additional analog and/or digital signals from external devices are routed consistently to all three redundant processors. This allows the system’s voting logic to continue functioning correctly, even with an expanded I/O count.
  • Expansion Function (EXT): The EXT designation signifies that this is a supplementary board. It is used when the primary terminal boards (such as the TBCB, TBQB, etc.) do not have enough physical connection points to accommodate all the sensors and actuators required for the application. It allows for a flexible and modular approach to expanding the I/O without compromising the system’s redundancy.
  • Signal Handling: The board provides a robust physical interface with a series of screw terminals for a wide range of signals. It ensures a reliable connection that is vital for the integrity of the data being fed into the system.

By providing a reliable and organized interface for expanded I/O, the DS200TBQDG1A ensures that the Mark V’s TMR architecture can perform its mission of continuous, fail-safe operation on larger, more complex systems.

الوصف

The GE DS200TBQDG1A is an External (EXT) Terminal Board for the Mark V Speedtronic turbine control system. It’s a critical component of the system’s Triple Modular Redundant (TMR) architecture, serving as an expansion board to accommodate additional field wiring for the three main control processors (R, S, and T).
