Switching Control and Protection Features

The GE DS200CDBAG1B DS200CDBAG1BCB Contactor Driver Board uses MOSFET switches for each output channel. Each channel includes a flyback diode for inductive load protection. The board provides status feedback for weld detection on each contactor. Furthermore, it includes programmable inrush current limiting for each output. Consequently, you can drive large solenoids without external suppression circuits.

Installation and Connection Steps

Mount this GE DS200CDBAG1B DS200CDBAG1BCB Contactor Driver Board in any Mark V rack slot. First, connect the DC supply voltage to the TB1 power terminals. After that, wire each contactor coil to the corresponding TB2 output. Then, attach the logic input cable to the 20-pin header. Finally, test each channel individually before enabling automatic control.

Energy Discharge and Safety Notice

This GE DS200CDBAG1B DS200CDBAG1BCB Contactor Driver Board stores energy in its snubber capacitors. Therefore, you must wait at least one minute after power removal. The eight capacitors discharge through internal bleeder resistors during this time. Never disconnect a contactor while the output remains active.

Status Indication and Diagnostics

Eight green LEDs show the active status of each driver channel clearly. A red LED illuminates when the board detects a welded contactor fault. A yellow LED flashes during the power-up self-test routine. These indicators help technicians troubleshoot contactor issues without special tools.
