About the DS200SDCIG2ABA
The DS200SDCIG2ABA is a DC Power Supply and Instrumentation Board from General Electric's Mark V Series. It provides power supply and instrumentation functions for industrial applications, ensuring accurate control, monitoring, protection, and diagnostics.
This "SDCI" board has a three-fold revision history: Functional Revision 1 (A-rated), Functional Revision 2 (B-rated), and Artwork Revision (A-grade).
Hardware Tips and Specifications
The DS200SDCIG2ABA features sophisticated circuits, including:
- Motor field power circuits (lacks the SCR module).
- Driver circuits for armature SCR gating.
- Instrumental AC and DC line motor circuits for armature current/voltage, field current, AC line current/voltage magnitude, and phase sequence signals.
The board also includes fuses (FU1-FU6) with corresponding LED indicators for circuit board protection.
There is also adjustable hardware such as Berg-type manually movable jumpers (JP1, JP2, SW1) for manufacturing, customer, or test options.
Installation Tips and Specifications
- The DS200SDCIG2ABA is a high-voltage PCB, requiring caution and respect during installation.
- Always turn off power to the PCB before attempting installation or replacement, as potentially lethal voltages can be present even after rest.
- The board is positioned behind the corresponding SDCC board in the drive assembly.
- To access the SDCI, disengage cabinet locks, lift and tilt the SDCC module forward.
- Gently remove ribbon cables or pull tab-connected cables, adhering to specific cable sensitivities.
- The SDCI board is held by detachable plastic snaps, which must be removed for replacement.
- During installation, ensure all components on the base plate are in the correct position (matching the previous board) and all connector cables are properly seated.
