DS200SDCIG2AFB

About the DS200SDCIG2AFB

The DS200SDCIG2AFB is a DC Power Supply and Instrumentation Board from General Electric's Mark V Series.

It's one of the final GE product series to incorporate the patented Speedtronic control system technology, first introduced with the Mark I Series.

This board is a revised version; the DS200SDCIG2 parent PCB was the original and lacks the DS200SDCIG2AFB's three significant product revisions. Despite revisions, it has a normal Mark V Series assembly version.

Hardware Tips and Specifications

This model provides logic power functions and interface circuitry for Mark V Series drive assemblies.

It is compatible with DC2000 drives having input voltages up to 600 V AC.

The board includes various circuits:

• Driver circuits for armature silicon controller rectifier (SCR) gating.
• Motor field power circuits (excluding SCR module use).
• External circuits, available due to its G2 group variation.

The DS200SDCIG2AFB functional product number indicates its:

• SDCI functional acronym.
• Normal assembly version.
• Normal style of PCB coating.
• Three significant product revisions.

It uses two manually configurable jumpers, labeled "JP", for customization.

This board is a static-sensitive model; use a standard wrist grounding strap during replacement.

Installation & Troubleshooting

• The DS200SDCIG2AFB is considered a primary replacement unit for other SDCI boards in the Mark V system.
• When replacing, power to the associated drive must be turned off to prevent property damage or personal injury.
• All configurable components on the new board must be set to match the previous board's jumper settings.
• Caution is advised when configuring jumpers, as damage could affect future operations.
• More information on installation procedures can be found in the GEI-100173 Instruction Manual.
