د.إ8,888.00

The DS200UDSAG1APR2 acts as the Display/Keyboard Interface and Controller for the generator’s excitation system, often integrated with GE’s EX2000 or EX2100 excitation drives.

  • Excitation Control Processing: It contains an 80196 microprocessor to execute the real-time control algorithms necessary to regulate the generator’s field current.2 This directly determines the generator’s output voltage and reactive power.
  • Diagnostic Interface: It provides immediate, on-board feedback for monitoring and troubleshooting:
    • Alphanumeric Displays: It typically features up to 21 4-character displays to show status codes and process values.3
    • Status LEDs: It includes up to 32 LEDs for quick visual indication of the board’s operational state and detected faults.4
  • Firmware: The board contains sockets for EPROM (Erasable Programmable Read-Only Memory) modules which store the system’s firmware and control programming.5

⚙️ Part Number Interpretation

The long part number signifies its specific revision history:

  • DS200: Identifies the board as being part of the Mark V Speedtronic Turbine Control System.6
  • UDSA: The functional acronym for this type of Excitation/Display board.
  • G1: Denotes the Group 1 hardware generation of the Mark V products.
  • APR2: The suffix indicates the specific revision level. In this naming convention, the APR2 suggests a series of functional/artwork revisions built upon the base G1A model.

This specific revision is often referenced alongside the DS200UDSAG1A base model in industrial parts listings.

As a legacy Mark V component, it is primarily sourced through specialized industrial parts suppliers and repair services.
