⚡ Key Functionality

The primary role of the 3$\text{DS200UDSAG1A}$ is signal processing and diagnostic communication within the excitation control loop:4

  • Excitation Control Processing: The board is equipped with an 80196 microprocessor to execute the system’s firmware and manage the complex control algorithms for the generator’s excitation system.5 This process is essential for regulating the output voltage and reactive power of the generator.
  • Signal Interface: It sends and receives control and feedback signals from various other boards and devices within the Mark V system through a 40-pin connector (often using a fragile ribbon cable).6
  • Operator Feedback: The board provides crucial diagnostic and operational status information directly to the operator or maintenance technician via on-board indicators:7
    • 4-Character Displays: Multiple displays (often up to 21) provide clear, concise alphanumeric status codes.8
    • LEDs: Up to 32 LEDs give quick, visual feedback on the board’s status and fault conditions.9

⚙️ Technical Details and Context

  • Series: Mark V Speedtronic Turbine Control System, 10$\text{DS200}$ series (Drive Board/Excitation Control Board).11
  • Compatibility: It is often found in systems integrated with GE’s EX2000 or EX2100 series excitation control modules.
  • Revision: The “A” at the end of the part number (12$\text{G1A}$) indicates it is a revised version of the original 13$\text{DS200UDSAG1}$ with a singular functional revision (rated at an ‘A’ grade for functionality).14
  • Legacy Status: Like most $\text{DS200}$ series boards, this component is part of a legacy control platform and is primarily supported through specialized repair and surplus markets.

Note on Handling: Due to the age and nature of the industrial connection, technicians must exercise care when handling the ribbon cable attached to the 40-pin connector to prevent damage to the cable or the connector itself.15
