The GE DS200CDBAG1B DS200CDBAG1BBB Contractor Driver Board manages contractor switching in Mark V drive systems. You will find this board in gas and steam turbine controls. It provides reliable signal transmission between the main controller and external contractors.
Additionally, the GE DS200CDBAG1B DS200CDBAG1BBB Contractor Driver Board uses optocoupler isolation on all input lines. This design blocks ground loop interference effectively. As a result, you achieve cleaner contractor coil switching. The board also supports hot-swap replacement in most cabinets.
Technical Specifications

The GE DS200CDBAG1B DS200CDBAG1BBB Contractor Driver Board stores no internal energy. Therefore, you do not need discharge procedures before handling. Use the 40-pin connector for all primary signal lines. Meanwhile, the two 3-pin terminal blocks handle auxiliary feedback loops.
Installation and Compatibility
This driver board replaces older GE contractor cards directly. For example, it fits into EX2100 and DC2000 cabinets seamlessly. Mount the GE DS200CDBAG1B DS200CDBAG1BBB Contractor Driver Board using four M3 screws. Afterwards, connect the ribbon cable to the J1 port firmly. Always verify the 24V supply polarity before you power up.
The DS200CDBAG1BBB variant requires firmware revision 2.1 or higher. Without this version, the board will not handshake with the main processor. You can update the firmware via the JTAG header. That header sits near the bottom-left corner of the PCB.
Environmental and Safety Data
This board operates reliably from -30°C to +65°C. It also withstands 5g vibration per IEC 60068-2-6. The component side has no conformal coating. Therefore, you should inspect it periodically for dust buildup. Use only compressed air for cleaning. Never apply liquid solvents to the GE DS200CDBAG1B DS200CDBAG1BBB Contractor Driver Board.
