Terminal Board TBTC

• The Terminal Board TBTC serves as the intermediary point for wiring the thermocouple inputs, providing a structured and reliable connection interface for these cables. It comprises two terminal blocks where the thermocouple cables are securely attached, ensuring a stable and organized setup for installation and maintenance tasks.
• By centralizing the wiring process onto the terminal board, it simplifies the connectivity between the thermocouple inputs and the VTCC processor board. This streamlined connection setup enhances efficiency in data transmission and processing, enabling seamless communication between the thermocouple sensors and the processing unit.
• Additionally, the terminal board's design ensures optimal signal integrity and reliability, minimizing the risk of signal interference or loss during transmission. This robust interface architecture enhances the overall performance and accuracy of the thermocouple measurement system, making it well-suited for demanding industrial environments where precise temperature monitoring is essential.

Connection to VME Rack

• To facilitate communication and data transfer, cables with molded plugs connect the terminal board TBTC to the VME rack where the thermocouple processor board is situated.
• This connection enables seamless integration of the thermocouple inputs into the overall control system architecture, ensuring real-time monitoring and control of temperature parameters.

Versatility and Adaptability

• The thermocouple board offers versatility and adaptability to meet the diverse temperature sensing requirements of industrial processes.
• By supporting multiple thermocouple types and providing a standardized interface for connection, the board accommodates various temperature measurement needs, enhancing flexibility and scalability in system design and implementation.

Fault Detection

High/Low Limit Check (Hardware):

• The fault detection system incorporates a high/low limit check mechanism to scrutinize critical parameters against predefined thresholds.
• This hardware-based approach involves dedicated circuitry designed to detect extreme values within the system. Sensors continuously relay data to the hardware, which compares these readings against predetermined high and low limits.
• When sensor data exceeds or falls below these thresholds, the hardware triggers alarms or initiates shutdown procedures, signaling potential faults or anomalies that require attention.

High/Low System Limit Check (Software):

• In tandem with the hardware-based limit checks, the fault detection system utilizes software algorithms to perform high/low system limit checks.
• This software-based approach involves the continuous monitoring of system-wide data trends and patterns. By analyzing aggregated sensor data and system parameters, the software identifies abnormal fluctuations or outliers that may indicate underlying issues.
• The high/low system limit check enhances fault detection capabilities, enabling proactive identification of potential faults or malfunctions before they escalate into critical issues.

Monitoring Readings from all TCs, CJs, Calibration Voltages, and Calibration Zero Readings:

• The fault detection system extends its monitoring capabilities to encompass readings from all temperature sensors (TCs), cold junctions (CJs), calibration voltages, and calibration zero readings. This comprehensive approach ensures that every aspect of the sensor network is scrutinized for abnormalities or deviations from expected values. Continuous monitoring of TCs and CJs allows for the detection of temperature variations, while calibration voltages and zero readings are monitored to ensure the accuracy and reliability of sensor measurements.
• By monitoring all TCs, CJs, calibration voltages, and zero readings, the fault detection system can identify potential faults or inaccuracies in sensor data. Timely detection of anomalies allows for prompt corrective action, minimizing the risk of system downtime or failure. Additionally, calibration voltages and zero readings play a crucial role in maintaining the accuracy of sensor measurements, ensuring precise temperature monitoring and control within the system.
