Description

The GE DS200CDBAG1ABA is a contactor drive board manufactured by General Electric (GE) for use in GE Speedtronic MKV gas turbine control systems.

Basic functions and features
Control contactor opening and closing:
The main function of the DS200CDBAG1ABA contactor drive board is to control the opening and closing operation of the contactor. It forces the contactor to close by applying a specific voltage (e.g. 105 VDC) for a certain period of time (e.g. 250 ms), and then adjusts the contactor drive current using an adjustable resistor (e.g. RV1) to keep the contactor closed.
Adjustable resistance RV1:
The drive board includes an adjustable potentiometer RV1 for setting the contactor drive current. This is an important feature to ensure that the contactor can work stably under different working conditions.
Enhanced diagnostic capabilities:
As part of the Mark V Series turbine control system, the DS200CDBAG1ABA features enhanced diagnostic capabilities to isolate faults to any card-level controller in triple redundancy.
Application field:
? The DS200CDBAG1ABA drive board is mainly used in industrial environments such as turbine systems, power plants and hydropower plants. In addition, it is also widely used in wind power and oil energy fields.
Safety and Maintenance:
Be sure to disconnect the power supply before use, and test the board to confirm that there is no residual power. Static electricity can damage the board, so it is recommended to work on the board using a ground strip and store the board in a static protective bag.
