Description
GE DS200SDCIG1ABA – DCI I/O Board for GE AC/DC-2000 Drives and EX2000 Excitation Systems
The DS200SDCIG1ABA is a DCI I/O interface board used in GE industrial drive platforms (AC-2000/DC-2000) and EX2000 excitation systems. From my experience, it serves as the analog/digital I/O bridge for the SDCC control board, consolidating field signals—analog loops, tach/pulse feedback, and discrete I/O—into a stable, noise-resistant interface. You might notice that plants often keep one on the shelf, because a fast swap typically brings a stopped line back online with minimal re-commissioning.

Key Features
- Consolidated field I/O – Routes analog, digital, and speed feedback to the SDCC, reducing wiring complexity in the cabinet.
- Analog signal conditioning – Typically supports ±10 V and 4–20 mA loops with onboard scaling/filtering for stable control.
- Tachometer/pulse feedback – Accepts speed/encoder-type signals for closed-loop drive performance.
- Opto-isolated discrete I/O – Helps protect the control core from field noise and transients in many cases.
- On-board diagnostics – Status indicators and test points simplify commissioning and fault tracing.
- Form-fit-function replacement – Designed for drop-in replacement within GE DS200 platforms to shorten downtime.
- Rugged PCB design – Built for cabinet environments where vibration and EMI are typical.

Application Fields
This board is typically deployed in high-demand industrial drive and excitation cabinets. Plants use it in steel and metals rolling lines, paper machines, mining conveyors, compressors, large fans/pumps, and turbine excitation panels (EX2000). One maintenance manager told us their spare DS200SDCIG1A swap “cut restart time from hours to under 30 minutes,” mainly because scaling and logic stayed aligned with the SDCC.
Advantages & Value
- Reliability – Stable I/O conditioning helps keep loops quiet, even in cabinets with heavy EMI.
- Compatibility – Designed to match GE DS200 architecture and SDCC interfaces, which reduces engineering time.
- Lower downtime risk – Form-fit-function replacement makes it ideal as a stocked spare.
- Cost efficiency – Extends installed-base life; avoids full system replacement.
- Technical support – We help with revision matching (G1, ABA) and jumper/signal scaling guidance during commissioning.
Installation & Maintenance
- Environment – Install in a sealed, ventilated control cabinet. Maintain clear airflow around heat-generating components.
- Wiring – Separate analog from high-voltage and motor leads. Use shielded twisted pairs for low-level signals; ground shields at one point.
- ESD & safety – Power down, wait for DC bus discharge, and use ESD protection. Verify backplane voltages before seating the board.
- Jumper/DIP settings – Confirm scaling, filter, and I/O mode jumpers match your application. Document positions before replacement.
- Routine care – Quarterly dust removal (dry air, non-abrasive). Annual checks of terminal tightness and I/O calibration. Firmware is typically not required on this I/O board; any parameterization resides in the SDCC.
Quality & Certifications
- Manufactured within GE’s quality system (ISO 9001 at the corporate level)
- CE/UL conformity typically applicable at the system level (drive/excitation cabinet)
- RoHS status varies by vintage; we can check the exact revision for you
- Warranty: 365 days replacement/repair coverage
Supporting Components (Commonly Paired)
- DS200SDCCG1A – SDCC control board interfacing directly with DS200SDCIG1ABA
- Power supply and I/O terminal assemblies for AC-2000/DC-2000 or EX2000 cabinets (model varies by system)
One thing I appreciate is how the DS200SDCIG1ABA keeps legacy GE drives productive without forcing a redesign. If you share your exact cabinet type and current revision, we’ll validate compatibility and jumper map so your team can swap it confidently during a planned stop—or a 2 a.m. emergency.
