GE DS200SDCIG2ABA Signal Conditioning Instrumentation Board – Mark VI Turbine Control Series
When a critical signal conditioning board fails inside a GE Mark VI turbine control panel, the consequences are immediate and severe: turbine trips, unplanned shutdowns, lost megawatt-hours, and costly emergency maintenance windows. The DS200SDCIG2ABA is the precision instrumentation interface that keeps analog sensor signals clean, conditioned, and accurately routed to the Mark VI controller core — without it, the entire turbine protection and control loop is blind. No replacement means no restart.
The DS200SDCIG2ABA occupies a specialized role within GE’s Mark VI Turbine Control System — one of the most widely deployed gas and steam turbine control platforms in the global power generation industry. As a Signal Conditioning and Interface (SDCI) board, it bridges the physical world of thermocouples, RTDs, pressure transducers, and vibration probes with the digital intelligence of the Mark VI controller. Its presence in power plants, combined-cycle facilities, and industrial cogeneration units across six continents underscores its irreplaceable position in the automation ecosystem.

Frequently Asked Questions
Q: Is the DS200SDCIG2ABA compatible with both Mark VI and Mark VIe systems?
A: The DS200SDCIG2ABA is primarily designed for the Mark VI platform. Compatibility with Mark VIe depends on your specific panel configuration and backplane revision. Please contact us with your panel details for confirmation.
Q: What is the difference between DS200SDCIG2ABA and DS200SDCCG1AFB?
A: Both are signal conditioning boards within the Mark VI family, but they differ in I/O channel count, connector layout, and firmware compatibility. The SDCI variant (DS200SDCIG2ABA) is optimized for instrumentation-heavy applications. Our engineers can help you identify the correct replacement.
Q: Do you provide a test report with the board?
A: Yes. All refurbished units ship with a functional test report. New surplus units include original packaging documentation where available.
Q: What is the typical lead time?
A: In-stock units ship within 1–3 business days after order confirmation. For out-of-stock items, lead time is typically 2–4 weeks depending on sourcing.
Q: Can you assist with installation or commissioning?
A: We provide technical documentation and remote guidance. For on-site commissioning support, we can connect you with certified GE service partners in your region.
