Product Introduction
GE DS200DCFBG2BNC is a DC Feedback (DCFB) board for GE Speedtronic turbine control systems. It is associated with the Mark V platform and has also been referenced in relation to the Mark VI system.
The DCFB board supports monitoring and feedback functions for drive and exciter applications. Typical monitored signals include armature current and voltage, field current, AC line current, AC line voltage amplitude, and phase sequence. The board also supports feedback scaling for the DC bridge voltage feedback VCO circuit and the DC motor voltage feedback circuit.
The board is equipped with 18 plug connectors and 9 plug-in connectors. The plug-in connectors are located at the upper-left area and are labeled V1 to V3, P1A, P2A, VM1A, VM1B, VB2A, and VM2BA. Configuration is performed through 7 DIP switches and 12 jumpers. Board status and protection are supported by 2 LEDs, 1 neon indicator, 3 fuses, and 5 TP test points.
Because DS200DCFBG2BNC is a legacy product and appears in both Mark V and Mark VI references, the exact system assignment, input voltage range, output rails, and DIP switch map should be verified from the physical board label and the applicable GE Speedtronic manual before installation.

Note: Public documentation confirms the connector layout, DIP switches, jumpers, indicators, fuses, and test points for DS200DCFBG2BNC, but the exact Mark V/Mark VI assignment, AC input range, DC output rails, and DIP switch settings should be confirmed from the board label and GE Speedtronic system documentation.
Quality Control Process (DYNAMIC GENERATION)
- Visual and label inspection. We check the PCB surface, connectors, DIP switches, jumpers, fuses, LEDs, neon indicator, and mounting hardware for damage or corrosion.
- Connector and continuity check. The 18 plug connectors and 9 plug-in connectors are verified for correct pin continuity and no short circuits.
- Configuration verification. The 7 DIP switches and 12 jumpers are recorded and compared against the original board or system documentation.
- Indicator and fuse check. The 2 LEDs, neon lamp, and 3 fuses are inspected for proper presence and condition.
- Final packaging. After passing inspection, the board is anti-static bagged and foam-packed for shipment.
Replacement Pitfall Guide (DYNAMIC GENERATION)
❗ Confirm Mark V vs. Mark VI assignment. DS200DCFBG2BNC appears in both Mark V and Mark VI references; system compatibility must be verified before installation.
❗ Verify DIP switch and jumper settings. Incorrect DIP switch or jumper configuration can cause improper feedback scaling or drive faults.
❗ Match connector labeling. The plug-in connectors V1–V3, P1A, P2A, VM1A, VM1B, VB2A, and VM2BA must match the existing harness layout.
❗ Do not assume the same ratings as DS200DCFBG1 variants. Suffix differences such as G1/G2 and L/C/N may affect configuration, revision, or application.
❗ Check fuse and indicator status. Blown fuses or abnormal LED/neon behavior should be investigated before returning the system to service.
❗ Use the 5 TP test points for verification. Voltage and feedback levels should be checked at the integrated test points during commissioning.
❗ Handle as ESD-sensitive equipment. Always use anti-static wrist straps and handling procedures during removal, installation, and storage.
Keep these in mind and you’ll cut 90% of rework time.
Compatibility Matrix & Benchmarks
