Functional Description

IS230TNTCH3B is a TI Assembly Module manufactured and designed by General Electric. It is a part of the Mark VIe Control System. The assembly comprises the TBTCH1B terminal board and one PTCCH1B pack. The terminal board serves as a central hub for connecting the thermocouple inputs, providing a convenient and organized interface. It is designed to accommodate multiple thermocouple inputs, enabling the monitoring of temperature at various points within the system. The PTCCH1B pack is responsible for conditioning and digitizing the thermocouple signals. It incorporates precision circuitry that amplifies, linearizes, and compensates for cold junction temperature variations. The pack ensures accurate and reliable temperature measurement by converting the thermocouple signals into digital data that can be effectively processed by the control system.

Operation

• The Module offers 24 thermocouple inputs that can be configured as either grounded or ungrounded. This flexibility allows for compatibility with different thermocouple wiring configurations commonly used in industrial applications.
• The thermocouple inputs can be located up to a distance of 300 meters (984 feet) from the turbine control panel. This extended cable length capability enables the placement of the thermocouples in various locations, even in large industrial environments. To ensure accurate temperature measurement over long cable runs, the maximum allowable two-way cable resistance is limited to 450 ohms. This restriction helps maintain signal integrity and minimizes the impact of voltage drop along the cable.
• To mitigate the effects of high-frequency noise, the assembly incorporates high-frequency noise suppression mechanisms. These mechanisms are designed to minimize unwanted noise interference that can affect the accuracy of temperature measurements. By suppressing high-frequency noise, the system can obtain clean and reliable thermocouple signals.
• The terminal board, a component of the assembly, is equipped with two cold junction reference devices. These devices play a crucial role in compensating for temperature variations at the cold junctions of the thermocouples. By accurately measuring and compensating for these variations, the assembly ensures precise temperature measurements.
• The analog-to-digital conversion of the thermocouple signals takes place in the I/O processor of the Mark VIe Control System. This conversion process involves transforming the analog signals from the thermocouples into digital format, allowing for precise and accurate temperature measurement. Additionally, the I/O processor performs the necessary linearization for each individual thermocouple type. This ensures that the non-linear characteristics of different thermocouples are properly accounted for, enabling precise temperature calculations.
• The integration of high-frequency noise suppression, cold junction reference devices, and the analog-to-digital conversion in the Assembly ensures accurate and reliable temperature measurement within the Mark VIe Control System. These features contribute to the system's overall performance and its ability to monitor and control temperature variables effectively in industrial applications.
