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.

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.
