|Origin||United States (US)|
The DS200TBQDG1ACC is a General Electric printed circuit board (PCB) component. This board is used within the Mark V system, which is a third-generation TMR (triple modular redundant) Speedtronic system. Such systems have been used for decades to manage and control large and small industrial gas and steam turbines with efficiency and reliability.
The DS200TBQDG1ACC PCB functions as an RST Extention Analog termination board. The board is built with a double terminal strip along one board edge that provides multiple screw connections for the user to attach wire points to the board. This board is designed with several jumper switches on its surface that can be used to change how the board functions. Refer to GE manuals for specifics on jumper settings.
Other board components on the DS200TBQDG1ACC circuit board include resistor network arrays and six vertical pin connectors. Additionally, the board has three lines of metal oxide varistors. These components are designed to protect circuitry from overvoltage conditions by shunting excessive voltage away from sensitive components.
The GE RST Extension Analog Termination Board DS200TBQDG1A features 2 terminal blocks. Each block contains 107 terminals for signal wires. The GE RST Extension Analog Termination Board DS200TBQDG1A also contains multiple test points, 2 jumpers, and 3 34-pin connectors. The jumpers are identified as BJ1 and BJ2 on the board. When you first install the board, you can use the jumpers to define the processing of the board to meet the specific requirements of the drive.
To do that the installer can use the information provided in the written material that came with the board. The jumpers each contain 3 pins on the board. One position is defined when two pins are covered by the jumper (for example pins 1 and 2). The other position is defined when two other pins are covered by the jumper (for example pins 2 and 3). Some jumpers support one jumper position only and cannot be moved by the installer. The alternate position is used at the factory for testing a specific circuit or function of the board.
When you are replacing the board because the original board is defective, the installer must examine the new board and the old board together and move the jumpers on the new board to the same position as found on the old board. The installer can either write down the jumper positions on the defective board and set the jumpers on the new board to be the same. Or, examine the boards side-by-side and move the jumpers on the new board to match the defective board.
