الوصف
The GE DS215TCCBG8BZZ01A is a specialized Analog I/O Card with firmware, used in the GE Speedtronic Mark V series of turbine and generator control systems. It is a critical component for processing and conditioning analog signals from various sensors and terminal boards.
Function and Purpose
The primary function of this board is to serve as the interface between the Mark V’s digital control system and the analog world of physical sensors and actuators. It’s located in the TC2000 C core in location 3. Its key roles include:
- Signal Conversion and Conditioning: It processes a variety of analog signals, including those from RTDs (Resistance Temperature Detectors), 4-20 mA current loops, and other inputs from terminal boards. The board converts these raw analog signals into a digital format that the main control processors can understand and use for control and protection.
- Data Bus Integration: The conditioned signals are then transferred to the main core processors via a dedicated data bus, specifically the 3PL connector. This ensures the main processors receive accurate data in real-time for turbine control and diagnostics.
- Firmware-Driven: The “w/firmware” designation means the board has dedicated, on-board software that defines its functionality. This firmware allows it to manage signal processing and communication independently, reducing the workload on the main processors.
- Advanced Diagnostics: This board has the potential for built-in diagnostic testing, including background and manually initiated routines, as well as software-implemented fault tolerance. This makes it a highly reliable component for mission-critical applications.
Technical and Design Features
The DS215TCCBG8BZZ01A is a robust, industrial-grade circuit board designed for reliability in harsh environments.
- Group 8 Product: The “G8” in the part number indicates that this board belongs to the eighth and a more modern grouping of Mark V products, representing a specific revision with a particular set of features and hardware.
- Connectivity: The board has multiple connectors to facilitate various functions. The 2PL connector distributes power from the system’s power supply. The JHH connector carries 4-20 mA inputs, while the JII connector is specifically for RTD inputs.
- Protection: The board is built with a protective coating to shield its components from environmental factors such as dust, moisture, and mild corrosive elements.
- Redundancy: This board can be used in both Simplex and Triple Modular Redundant (TMR) redundancy applications, which is a key feature of the Mark V system.
