FUNCTIONAL DESCRIPTION:

DS200TCQFG1ACB is a TC2000 Analog I/O Extension Board manufactured and designed by General Electric as part of the Mark V Series used in GE Speedtronic Gas Turbine Control Systems. This board allows the main controller to interface with additional analog sensors and actuators, enabling precise monitoring and control of process variables such as temperature, pressure, flow, and level. The board typically supports multiple analog channels, offering flexible voltage and current signal ranges like 0–10V or 4–20mA. Engineered with high-resolution converters and signal isolation features, the TC2000 Analog I/O Extension Board enhances the performance and scalability of critical control systems.

INSTALLATION:

The board is typically connected to the main TC2000 controller via a backplane connector or dedicated ribbon cable, ensuring reliable data and power transfer. Before installation, power to the system should be turned off to avoid any electrical hazards. Once mounted, input and output wiring are connected to the terminal blocks—these may include shielded cables for analog signals to minimize interference. Proper labeling and adherence to wiring schematics is essential to maintain system integrity and ensure accurate data acquisition and output functionality.

OPERATION:

The controller communicates with the board to read analog input signals from field sensors and to send analog output signals to devices like control valves or actuators. The high-resolution analog-to-digital and digital-to-analog converters ensure that signal accuracy is preserved, which is critical in tightly controlled environments. The system software, often programmable via HMI or SCADA, allows operators to configure input scaling, set output ranges, and monitor real-time performance. Diagnostic features may also be available to detect wiring issues, signal loss, or calibration errors, ensuring robust and reliable system operation over time.
