DS3800NTBE | General Electric Printed Circuit Board

The DS3800NTBE is a thermocouple card specifically designed for integration within the Mark IV system, which is utilized for managing gas and steam turbines. The Mark IV system incorporates triple modular redundancy to ensure reliability across all parameters and critical controls. 

The thermocouple card DS3800NTBE plays a crucial role within this system. It is employed to interface with various thermocouples distributed throughout the Mark IV system. For instance, the system employs thirteen exhaust thermocouples distributed as follows: four thermocouples for R, five for S, and four for T. These thermocouples measure temperature and calculate median values, which are then communicated back to the system’s control unit, <RST>. This setup ensures that the turbine operation is consistently monitored and managed based on readings from these thermocouples. Proper functioning of all thermocouple cards is essential, as deviations or erroneous readings from any single card could result in a temperature bias, potentially leading to a significant reduction in turbine performance and output.
