Driver Architecture and Output Configuration
The GE DS200CDBAG1B DS200CDBAG1BCB features four independent contactor driver channels. Each channel provides 24 V DC at 2 amperes continuous current. The board drives pre-charge, line, bypass, and brake contactors. An internal flyback diode protects each output from inductive kickback. The GE DS200CDBAG1B DS200CDBAG1BCB includes a 5 ampere inrush capability for 100 milliseconds. This capacity suits DC contactors with heavy coil loads.
Input Interface and Control Logic
This contactor driver board accepts four 24 V DC input signals. Each input draws only 10 milliamperes from the control board. Optocouplers provide 2500 V RMS isolation between inputs and outputs. The DS200CDBAG1B DS200CDBAG1BCB responds to input changes within 10 milliseconds. It turns off outputs within 15 milliseconds after input removal. Four red status LEDs illuminate when each contactor output activates.
Protection Features and Fault Handling
The GE DS200CDBAG1B DS200CDBAG1BCB includes comprehensive output protection circuits. Short-circuit protection shuts down any overloaded channel immediately. Overcurrent protection limits each channel to 3 amperes maximum. A fast-blow fuse on the 24 V supply protects against major faults. The board automatically restores output after removing the fault condition. Thermal protection prevents damage from continuous overload situations.
Physical Dimensions and Installation Guidelines
The GE DS200CDBAG1B DS200CDBAG1BCB weighs 0.450 kilograms for secure mounting. Its height measures 250mm, width 120mm, and depth 30mm. Install this board adjacent to the power supply board in AC2000 drives. The board consumes 3 watts from the 24 V DC supply. It operates reliably from 0°C to +50°C ambient temperature. Use proper ESD handling procedures during installation.
Energy Storage and Holding Capacitance
The DS200CDBAG1B DS200CDBAG1BCB includes a 100 µF holding capacitor per channel. These capacitors maintain contactor coil current during supply voltage dips. They also filter noise on the 24 V DC power rail. The capacitors discharge within 30 seconds after removing input power. Wait one minute before servicing the GE DS200CDBAG1B DS200CDBAG1BCB for safety. No battery is present on this contactor driver board.
