The board serves as the computing and control core of the Mark V system. It continuously collects key operating parameters such as turbine speed, temperature and pressure through its I/O channels. Based on preset control logic, it processes the collected data quickly and sends precise control commands to the turbine’s execution components, thereby maintaining the turbine’s operation within the optimal parameter range.
It integrates multiple protective components including capacitors, rectifiers, diodes, transistors and integrated circuits to limit voltage and condition signals. The built-in 125VDC-rated fuses can quickly cut off the circuit when encountering abnormal current such as voltage surges. In addition, status LEDs are configured to immediately alert operators to fuse failures or circuit malfunctions, preventing damage to the entire control system.
It realizes efficient data interaction and collaborative work with analog I/O boards, digital I/O boards and other modules in the Mark V system. It integrates the signal data from various functional boards, uniformly processes and distributes control instructions, ensuring the coordinated operation of all parts of the turbine control system and forming a complete monitoring and control loop.
It has powerful programmable capabilities that allow technicians to modify and update the control logic stored in the flash memory according to the specific models and operating requirements of different gas or steam turbines. This adaptability enables the board to be applied to a variety of turbine control scenarios without the need for large-scale hardware modifications.
It is widely used in the Mark V control systems of gas and steam turbines in thermal power plants. It monitors and regulates parameters such as steam pressure, turbine speed and exhaust temperature in real time during the power generation process. It ensures the stable output of electric energy and triggers timely protection measures when abnormal parameters occur, avoiding major failures that could affect the power supply of the entire plant.
In petrochemical refineries and chemical processing facilities, many compressors and pumps are driven by steam turbines. This board is integrated into the supporting Mark V control systems. It controls the operating state of the turbines to match the speed and pressure requirements of the oil and gas compression and transportation processes, ensuring the continuity and safety of the petrochemical production chain.
For various industrial fields that still rely on the legacy Mark V turbine control system, such as metallurgy and chemical fiber production, the DS200TCPAG1AJD is a key maintenance spare part. When the original control processor board fails, replacing it with this board can quickly restore the normal operation of the turbine control system, minimizing production downtime caused by equipment outages.
In large-scale manufacturing enterprises such as cement and paper mills, small and medium-sized turbines are often used for self-supply of power and steam. This board is used in the Mark V control systems of these turbines. It adjusts the turbine’s output power in real time according to the enterprise’s production load changes, balancing energy supply and consumption and improving the overall energy efficiency of the enterprise.
