The DS200CDBAG1A is a specialized Contactor Driver Board developed by General Electric for the Driver Control series. This printed circuit board is designed to facilitate the reliable operation of contactors in industrial automation, power generation, and heavy-duty manufacturing applications. It is engineered to regulate coil voltage and manage switching operations, contributing to consistent system performance. The board includes an integrated 4 amp, 125V fuse (FU1) for circuit protection and supports input power within the 75 to 140 V ac/dc range.
Features
Integrated 4A, 125V fuse (FU1) for overcurrent protection.
Supports input power range of 75 to 140 V ac/dc.
Provides regulated contactor coil voltage output between 30 and 40 V dc.
Onboard LED indicator for visual monitoring of the local contact close command status.
Equipped with three diagnostic test points referenced to the CDBA common (ACOM).
Installation Guidelines
Ensure all power is disconnected from the drive cabinet before attempting to install or remove the board.
When replacing an existing unit, the RV1 potentiometer must be manually set to match the exact position of the original board to ensure compatibility with connected contactors like the DS304 series.
Use only isolated test equipment when measuring at the three test points to prevent short circuits, as ACOM is electrically isolated from standard drive common.
Adhere to standard ESD (Electrostatic Discharge) precautions when handling the PCB to prevent damage to sensitive electronic components.

FAQ
What is the primary function of the potentiometer RV1 on this board?
The RV1 potentiometer is used for calibration. It is critical that the setting on a replacement DS200CDBAG1A matches the previous board exactly; failure to calibrate this properly can lead to contactor coil failure, particularly when used with DS304-type contactors.
Are the test points on this board referenced to the drive common?
No. The three onboard test points are referenced to the CDBA common (ACOM), which is distinct from the drive common. You must use isolated measurement tools to avoid electrical issues.
