About the DS200SDCIG1A

General Electric DS200SDCIG1A DC Power Supply and Instrumentation Board: Overview

• The DS200SDCIG1A is a DC Power Supply and Instrumentation board originally manufactured by General Electric for the Mark V Turbine Control System Series.
• The Mark V Series has applications in the management and control systems of wind, steam, and gas turbine automated drive assemblies.
• It is now considered an obsolete legacy product series as its production and design have been discontinued.
• Despite its obsolescence, the Mark V Series is notable as one of the final GE product series to utilize the patented Speedtronic control system technology.
• The DS200SDCIG1A is not the original board for this functional role in the Mark V Series; the original was the DS200SDCIG1 parent board, lacking the DS200SDCIG1A's single A-rated functional product revision.
• It serves as an interface to DC2000 drives.

Hardware Tips and Specifications

• Fuse Diagnostics: Each fuse has an LED indicator that illuminates when the associated fuse blows, improving troubleshooting.
• Safe Inspection Procedure (from manual):
  1. Open the cabinet where the board is installed.
  2. Inspect the board for any lit LED lights (do not touch due to potential high-voltage).
  3. Record the fuse identifier information.
  4. Crucially, remove all current from the drive.
  5. Open the cabinet again and test the board to ensure all power is removed (allow time for power to dissipate).
  6. Inspect the board for wiring errors or shorts if applicable to the blown fuse.
  7. If the board is defective, remove and replace it.
  8. When removing, avoid touching other boards/devices, panels, cables, or plastic snaps.
  9. Carefully disconnect all cables, holding both connectors when separating ribbon cables.
• Voltage Regulation: The board is a well-voltage-regulated product with an elevated number of fuse components.
• Fuse Components: Fuses are accompanied by FU1-FU6 factory-printed nomenclature labels. Examples include:
  • FU1: For 115 V ac power supply to 3TB.
  • FU2: For +24, +15, and +5 V dc signal-level power supplies.
  • FU3: For -24 and -5 V dc signal-level power supplies.
  • FU5 & FU6: For internal NRX 10 A field and/or MOV assembly.
• Customizable Hardware: Includes three customizable components:
  • JP1 MD control source jumper
  • JP2 MA ac contactor drop-out time jumper
  • SW1 Select ac line burdens as a function of nominal output current switch

Important Considerations

• All digits are important when ordering this board; ensure the correct SDCI board for your specific application.
• The board's originally-introduced performance specifications have been impacted by its A-rated functional product revision.
• Manufacturer-provided installation and storage parameters must be followed to prevent accidental or preventable damages.
• Refer to the device’s manual and datasheet for a complete wiring and installation guide.
