GE DS200SDCIG1AGB | Digital signal processing board

1. Model Attribution and Functional Positioning

• Series Positioning:
  It belongs to the GE Mark V series drive control system, a classic industrial drive control platform widely used in speed regulation and control of gas turbines, steam turbines, large motors, and other equipment. The prefix "DS200" typically denotes digital control boards in this series, which undertake core functions such as signal processing and logical operations.
• Core Functions:
  As a digital signal processing board, its main role is to receive real-time signals (e.g., motor speed, current, voltage) from sensors and encoders, perform filtering, calculation, and conversion through built-in algorithms, and then transmit the processed signals to the main control board (such as DS200SDCCGIAFD) to achieve precise control of the drive. Additionally, it coordinates data interaction between modules to ensure efficient execution of control commands.

2. Technical Characteristics and Hardware Composition

Key Technical Parameters

Hardware Composition

• Integrates a high-performance digital signal processor (DSP) responsible for real-time signal 运算 and filtering;
• Includes signal conditioning circuits to amplify and isolate raw input signals, reducing noise interference;
• Equipped with memory (RAM/ROM) for temporarily storing operational data and 固化 control algorithms;
• Features on-board indicator lights (e.g., power light, communication status light) for quick diagnosis of hardware faults.

3. Application Scenarios

• Industrial Drive Systems: Mainly used in speed control of gas turbines and steam turbines, as well as drive systems of large AC/DC motors. It processes key parameter signals of motor operation to ensure stable equipment performance.
• Closed-Loop Control Support: In speed and torque closed-loop control, it enhances system response speed and control precision by accurately processing feedback signals, suitable for scenarios requiring high dynamic performance (e.g., power plants, metallurgical production lines).

4. Collaborative Relationship with Other Series Boards

• Cooperates with main control boards (e.g., DS200SDCCGIAFD): Receives instructions from the main controller and feeds processed signals back to it, forming a control closed loop;
• Collaborates with I/O boards (e.g., DS200IOVAG1A): Receives on-site signals from I/O modules, processes them, and transmits them to the control system, while converting control commands into executable signals for output.

5. Notes

• Compatibility: Only applicable to GE Mark V series drives and not directly compatible with boards from other series (e.g., Mark VIe). When replacing, ensure the drive model matches;
• Maintenance and Replacement: Replace under power-off conditions and re-calibrate signals (using GE's dedicated configuration software, such as ToolboxST) to ensure signal processing accuracy;
• Data Acquisition: Official detailed datasheets need to be obtained through GE's official channels or authorized distributors, containing technical details such as specific pin definitions and calibration steps.
