Description
Product Description
The DS200DCFBG2B is a GE General Electric Mark V DC Power Supply and Feedback Board, also identified by the associated DS200DCFBG2BNC revision/configuration. The DCFB board is used in GE Mark V control and drive applications for power supply functions and feedback signal processing. It provides multiple connections for AC line, DC bridge, motor or generator feedback, and other system signals. The board includes configurable DIP switches, jumpers, test points, fuses, transformers, and diagnostic indicators. The exact wiring and configuration must be matched to the original Mark V equipment before replacement.

FAQ
Q1: What is the DS200DCFBG2B used for?
It is a GE Mark V DCFB board used for DC power supply and feedback functions in compatible control and drive systems.
Q2: What is the difference between DS200DCFBG2B and DS200DCFBG2BNC?
DS200DCFBG2B is the primary board designation, while DS200DCFBG2BNC identifies a later configuration/revision of the DCFB board. The complete part number should be matched to the installed equipment.
Q3: What connectors are used on this board?
The board has 18 plug connectors and 9 stab connectors. The stab terminals include V1, V2, V3, P1A, P2A, VM1A, VM1B, VM2A, and VM2B in documented DCFB configurations.
Q4: Is this board compatible with every Mark V system?
No. Mark V boards can have different functional and artwork revisions. Verify the complete board number, terminal connections, jumpers, DIP-switch settings, and system application before replacement.
Q5: Is the DS200DCFBG2B still manufactured?
The DS200/Mark V platform is a legacy GE control platform. Original replacement boards are generally sourced from industrial automation spare-parts inventories.
Troubleshooting & Safety
Before installation, compare the existing board’s complete part number and revision with the replacement. Record the original DIP-switch and jumper positions before removing the board. Inspect all connectors, fuses, terminals, and PCB components for damage or contamination. The DCFB board can interface with hazardous AC and DC power circuits, so power must be isolated and verified before servicing. DC bus and stored-energy circuits may remain energized after shutdown; follow the equipment manufacturer’s lockout/tagout and discharge procedures. Never change jumpers, switches, or wiring while the equipment is energized unless the applicable GE maintenance procedure specifically permits it.
