GE DS200DCFBG2BNC Power Supply & Instrumentation Board – Stable Control Power for Mark V Systems
The GE DS200DCFBG2BNC (MRP569662) is a GE Mark V series power supply and instrumentation board designed to generate the regulated control voltages that logic and I/O cards depend on. In many cases, this board sits at the heart of the cabinet, providing +5 VDC for logic, ±15 VDC for analog circuits, and a 24 V utility rail. From my experience, the BNC revision is favored in service teams because it tends to be a straightforward drop-in when replacing earlier G2 variants, with no wiring changes in standard Mark V racks.
Typical use is in gas/steam turbine control (Speedtronic Mark V) and related GE industrial drive or excitation assemblies that share the DS200 architecture. One thing I appreciate is how easy it is to verify health on this board—status LEDs and test points usually give quick confirmation of rail stability during commissioning or after a swap.
Order Placement Process and Guarantees
- Warranty: 365 days
- Delivery: 1 week if in stock; no more than one month at the latest
- Payment: 50% advance payment; full payment prior to delivery
- Express Options: FedEx, UPS, DHL
Key Features
- Regulated Multi-Rail Output: Typically provides +5 VDC, ±15 VDC, and 24 V rails for Mark V logic and analog I/O, helping stabilize the entire control stack.
- Backplane Integration: Plugs directly into the DS200/Mark V backplane; no field rewiring in standard G2 cabinets.
- Health Indicators & Test Points: On-board LEDs and accessible test points simplify diagnostic checks during startup and maintenance.
- Robust Filtering & Protection: Input conditioning and over-voltage/over-current protections that, in many cases, reduce nuisance trips from power disturbances.
- BNC Hardware Revision: This later revision typically improves reliability and compatibility versus early builds within the G2 family.
- Field-Proven Form Factor: Fits the established Mark V card rack layout; technicians can swap it quickly with basic ESD precautions.
Technical Specifications
| Brand / Model | GE – DS200DCFBG2BNC (Alt. Ref: MRP569662) |
| HS Code | 8538.90 (Parts for control panels/apparatus of 8537) |
| Power Requirements | Input derived from cabinet supply (commonly 125 VDC or 120 VAC via rectification, depending on system build); regulated outputs typically include +5 VDC, ±15 VDC, and 24 VDC to the backplane. |
| Dimensions & Weight | Approx. board size follows standard DS200/Mark V card format (around 330 × 280 mm); weight ~0.9 kg. Values may vary slightly by revision. |
| Operating Temperature | 0 to +60 °C typical control cabinet environment; non-condensing humidity. |
| Signal Input/Output Types | Regulated DC power rails to backplane; status LEDs; service test points. No direct field I/O. |
| Communication Interfaces | None (board interfaces via Mark V backplane connectors; no external fieldbus). |
| Installation Method | Plug-in board for Mark V rack; secured with standoffs/screws; uses keyed edge/backplane connectors. |
| Typical Compatibility | GE Speedtronic Mark V systems and DS200-series cabinets built for G2 hardware sets. |
Application Fields
- Gas and steam turbine control cabinets (Speedtronic Mark V), where stable logic and analog power rails are essential.
- Industrial drives and excitation systems that share DS200 backplane architecture.
- Planned maintenance programs and life-extension projects requiring like-for-like power board replacements.
- Emergency spares for plants prioritizing fast MTTR and minimal cabinet rework.
You might notice that many plants keep one DS200DCFBG2 on the shelf. A maintenance manager told us they swapped this board during a night shift, verified rails at test points in under 10 minutes, and had the unit back online before start of shift—no parameter changes required.
Advantages & Value
- Reliability: Proven in long-running Mark V fleets; the BNC revision seems to be stable in most cabinets.
- Compatibility: Drop-in with G2 hardware sets; no harness changes in typical configurations.
- Cost Control: Replacing the power board often prevents broader controller replacements, cutting downtime and parts cost.
- Supportability: Clear health indication and easy measurement points simplify troubleshooting for technicians.
Installation & Maintenance
- Environment: Install in a clean, ventilated control cabinet; maintain airflow around heat-producing components.
- Wiring & Grounding: Verify cabinet grounding and backplane connectors are clean; inspect standoffs and ensure firm seating.
- Safety: Isolate power, discharge stored energy, and observe ESD precautions. Confirm correct board orientation and connector keying before power-up.
- Commissioning Checks: Measure +5 V, ±15 V, and 24 V rails at test points; verify LEDs and alarm-free status on the controller HMI.
- Routine Care: Quarterly dust removal with dry, oil-free air; annual inspection of capacitors and connector wear.
- Firmware: No firmware updates required; track board revision for fleet consistency.
Quality & Certifications
- Manufactured within ISO 9001–controlled environments (typical for GE production).
- CE compliance at the system level for Mark V cabinets; board-level markings vary by revision.
- UL/CSA recognition generally applies to the assembled cabinet; board status can vary by build/version.
- RoHS status may vary for legacy revisions; many earlier units pre-date RoHS—check current stock if your site requires RoHS.
- Warranty: 365 days hardware warranty as stated above.
Note: Specifications are based on typical DS200DCFBG2 implementations in Mark V systems. If you’re matching a specific cabinet or revision set, share the system tag and we’ll verify compatibility against your hardware list before shipment.
