GE DS200CDBAG1B DS200CDBAG1BDB Contactor Driver Board

Key Technical Specifications

This GE DS200CDBAG1B DS200CDBAG1BDB board accepts 120V AC control input power. It drives four independent contactor coils with 5A continuous current each. The unit measures 22 cm in length, 15 cm in width, and 4 cm in height. Its total weight equals 0.7 kg without any packaging materials.

The GE DS200CDBAG1B DS200CDBAG1BDB includes four relay output channels for contactor switching. Additionally, it features one optocoupled input port for external enable signals. A single 10-pin terminal block connects the AC supply and contactor wiring. The board contains 4 relays, 4 snubber circuits, 8 diodes, 1 optocoupler, and 12 resistors.

GE DS200CDBAG1B DS200CDBAG1APR2 stores energy using one high-voltage capacitor. This capacitor provides 100 µF at 250V rating for relay coil hold-up. Consequently, the board maintains contactor closure during 30 millisecond power dips. Therefore, it prevents unintended contactor dropout in industrial environments.

Design and Integration

Both the GE DS200CDBAG1B and GE DS200CDBAG1BDB versions share identical driver circuitry. These boards use two-layer PCB construction with isolated relay zones for arc protection. Therefore, the GE DS200CDBAG1B DS200CDBAG1BDB operates reliably from -10°C to +55°C ambient temperature.

For installation, you need M3 screws for the four mounting holes. The board draws 100 mA typical control current from the 120V AC supply. Each relay includes manual test push buttons for troubleshooting. We recommend using 18 AWG wire for contactor coil connections.

Practical Application

This driver board controls motor starters and power contactors in automation panels. It receives enable signals from a PLC or turbine controller. The GE DS200CDBAG1B DS200CDBAG1BDB then energizes contactor coils sequentially. Therefore, it provides reliable switching for pumps, fans, and auxiliary systems in power plants.
