GE DS200DTBDG1A MKV, Terminal Board, Relay/Solenoid

The model number provides a clear breakdown of its function:

  • DTBD (Digital Contact Terminal Board): This board is a type of digital I/O interface. The “D” in the designation often implies a specific application or feature, distinguishing it from other digital I/O boards. In this case, the board is designed to handle the unique electrical characteristics of inductive loads.
  • Relay/Solenoid Control: This is the most critical feature. When a relay or solenoid is de-energized, its magnetic field collapses, generating a powerful high-voltage spike (back electromotive force or EMF). A standard digital output board could be damaged by this voltage. The DS200DTBDG1A is specifically engineered with built-in suppression circuitry (e.g., flyback diodes) to safely dissipate this back EMF, protecting the sensitive control electronics from damage and ensuring the longevity and reliability of the system.
  • Terminal Board: This board provides the physical gateway for field wiring. It uses robust screw terminals and high-density connectors to allow direct connection of external devices, simplifying wiring and providing a standardized, easily accessible interface.
  • MKV (Mark V): This board is a component of the GE Mark V Speedtronic turbine control system, known for its high reliability and triple-redundant architecture. The DS200DTBDG1A plays a vital role in providing the high-power digital outputs needed to control critical turbine auxiliaries.

In essence, this board is a purpose-built safety and reliability component, ensuring that the control system can safely and effectively actuate powerful devices in the field without risking damage to its own delicate internal electronics.
