DS200SDCIG2AGB

About the DS200SDCIG2AGB

• The DS200SDCIG2AGB is a DC Power Supply and Instrumentation Board manufactured by General Electric for the Mark V Turbine Control System Series.
• The Mark V Series is designed for control and management systems of wind, steam, and gas turbine automated drive assemblies.
• It's considered wholly obsolete due to manufacturing discontinuation, but it's one of the final GE Mark series to incorporate patented Speedtronic control system technology.
• This board is a revised product; the DS200SDCIG2 parent PCB was the original and lacks the DS200SDCIG2AGB's three significant product revisions.

Hardware Tips and Specifications

• The DS200SDCIG2AGB serves as an interface to DC2000 drives.
• Its voltage suppression strategy relies on Mark V Series standardized voltage-limiting components, including resistors, capacitors, diodes, and specialized integrated circuits.
• The board is populated with three unique adjustable hardware components:
  • JP1 MD Control Source Jumper
  • JP2 MA AC Contactor Drop-out Time Jumper
  • SW1 Select AC Line CT Burdens as a Function of Nominal DC Output Current Switch

Installation Guidelines & Safety

• Verify the correct board: Match the model and catalog numbers on the box label and the board's edge.
• Initial handling: Remove from static-protective package, place on top of the bag, inspect for identifying information, record it, then return to the bag.
• Replacement steps (for experienced servicers only due to high voltage):
  1. Turn off all current to the drive completely. Refer to drive documentation for full power removal instructions.
  2. Test all circuits to verify power is off.
  3. Wait a few seconds for current to dissipate from capacitors.
  4. Open the cabinet. Another board is typically in front of the DS200SDCIG2AGB; tilt it forward to expose the DS200SDCIG2AGB.
  5. Remove all cables carefully, labeling them if necessary, to avoid damage and aid reconnection on the replacement board.
