GE DS200SDCCG1AFD Drive Control Board – Central Control Card for DC2000/AC2000/EX2000 Systems
The GE DS200SDCCG1AFD is the SDCC (Drive Control) board used as the main control card in many GE DC2000, AC2000, and EX2000 drive and exciter cabinets. From my experience, this board handles the core drive algorithms, coordinates feedback signals, and communicates with the surrounding I/O and power boards. The “AFD” suffix indicates a later artwork/functional update within the G1 family, which typically improves compatibility and noise immunity in retrofit and maintenance scenarios.

Key Features
- Primary drive controller – Orchestrates speed/torque loops and overall drive logic for GE DC2000/AC2000/EX2000.
- Mixed-signal I/O – Accepts analog references and feedback (typically ±10 V or 4–20 mA via conditioning) and 24 VDC discrete signals, then outputs control references to power and I/O boards.
- Industrial communications – Provides service/diagnostic serial access (commonly RS‑232) and an RS‑485 style link used within the drive cabinet.
- Revision “AFD” enhancements – Later artwork/functional revisions that, in many cases, improve stability and interchangeability within the G1 series.
- Service-friendly design – Pluggable headers and ribbon connectors streamline swap-outs during planned shutdowns.
- Non-conformal build (DS200 series) – Typically supplied without conformal coating, making inspection and field repair more straightforward.
Technical Specifications
| Brand / Model | GE DS200SDCCG1AFD (SDCC Drive Control Board) |
| HS Code | 8538.90 (Parts for electrical control/distribution equipment) |
| Power Requirements | Supplied from the drive backplane: typically +5 VDC (logic) and ±15 VDC (analog); power draw usually < 10 W |
| Dimensions & Weight | Approx. 280 × 190 mm; ~0.5 kg (board only) |
| Operating Temperature | 0 to +60 °C (cabinet, non‑condensing), as typically specified for GE drive electronics |
| Signal I/O Types | Analog references/feedback (±10 V, 4–20 mA with conditioning), 24 VDC digital I/O via opto‑isolated inputs, tach/frequency feedback (drive dependent) |
| Communication Interfaces | RS‑232 service port; internal RS‑485 style link; multiple ribbon headers to adjacent GE boards (e.g., feedback/power interface) |
| Installation Method | Rack/backplane mounting inside GE DC2000/AC2000/EX2000 enclosures; secured with standoffs and keyed connectors; ESD-safe handling |
| Compatible Systems | Commonly used in GE DC2000, AC2000, EX2000 drive/exciter cabinets; retrofit‑friendly within G1 family when firmware matches application |
Commonly Paired Components
- DS200DCFBG1A – Drive Control Feedback Board (conditions analog feedbacks, often mated to SDCC)
- DS200DTBA / DS200DTBB – Terminal boards for discrete I/O terminations
- DS200DSPCG / DS200SDRM – Signal distribution or protection interfaces depending on cabinet design
One thing I appreciate is how the SDCC keeps swap‑outs predictable: when you carry over the original firmware set and retain the same daughter connectors, downtime stays short. A maintenance lead at a paper mill told me their team swapped an SDCC during a 4‑hour window and were back to production with only a quick loop tune.
Application Fields
This board is a fit for medium‑to‑large GE drive cabinets where reliable closed‑loop control is mandatory. You’ll often see it in:
- Metals processing – mill stands, coilers, unwinders needing tight torque control
- Pulp & paper – sectional drives on winders, coaters, and calendar stacks
- Power generation – exciters (EX2000) for generators
- Oil & gas / mining – conveyors, compressors, and pump drives
- Water & wastewater – high‑horsepower blowers and pumps
Advantages & Value
- Reliability – Proven in harsh industrial duty; the AFD revision seems to add tolerance to electrical noise in many cases.
- Compatibility – Drop‑in for many G1 builds when firmware and optioning match; reduces re‑engineering risk.
- Lifecycle savings – Keeps legacy DC2000/AC2000/EX2000 assets running, deferring multi‑million cabinet replacements.
- Technical support – We can help verify firmware part numbers, connector population, and quick commissioning steps.
Installation & Maintenance
- Cabinet environment – Install in a clean, ventilated enclosure; maintain airflow around boards. Keep ambient 0–60 °C, non‑condensing.
- Wiring & grounding – Observe drive grounding schemes. Route low‑level analog away from high‑frequency power cables to minimize noise pickup.
- ESD precautions – Handle with a grounded wrist strap; power down and wait for DC bus discharge before removal.
- Firmware transfer – Move the original firmware devices (EPROMs/Flash daughter parts, if present) from the old board to retain application behavior.
- Routine care – Annual dust cleaning with dry air; check ribbon connectors for oxidation; verify analog calibration and update drive firmware when recommended by site standards.
Quality & Certifications
- Typically CE and UL compliant at the system level when installed in GE drive cabinets
- Manufactured under GE quality systems; ISO-based factory processes
- RoHS status may vary for legacy builds; many installed bases predate mandatory RoHS
- Warranty: 365 days
