• Flexible Signal Conditioning: The adjustable anti – aliasing filters and basic signal – conditioning functions allow for customization according to the specific requirements of different applications.
• Easy Integration: It can be easily integrated into the SCXI system, which simplifies the setup and configuration of the data – acquisition system. Users can use the same software tools to manage and analyze the data from different SCXI modules.

5. Stability and Reliability

• Robust Construction: The SCXI – 1104C is built with a durable housing that can withstand harsh industrial and laboratory environments, including dust, moisture, and mechanical vibrations.
• Quality Components: It uses high – quality electronic components that are selected for their reliability and long – term performance. This helps to ensure stable operation over an extended period.
• Calibration and Self – Diagnostic: The module can be calibrated to maintain measurement accuracy over time. It also has self – diagnostic functions that can detect internal faults and abnormal operating conditions, which helps in quick troubleshooting and maintenance.

6. Real – World Examples

• Automotive Engine Testing: In an automotive engine testing facility, the SCXI – 1104C is used to measure the pressure inside the engine cylinders, the temperature of the exhaust gases, and the vibration of the engine block. The 8 differential input channels allow for simultaneous measurement of multiple parameters. The high – resolution measurement and fast sampling rate enable engineers to capture the dynamic behavior of the engine under different operating conditions. The data collected by the SCXI – 1104C is used to optimize the engine design and improve its performance.
• Power Plant Monitoring: In a power plant, the SCXI – 1104C is used to monitor the temperature and pressure of steam in the boiler and turbine systems. The analog inputs are connected to temperature sensors and pressure sensors installed in the steam pipelines. The anti – aliasing filters ensure accurate measurement of the high – frequency fluctuations in the steam parameters. By continuously monitoring these parameters, the power plant operators can detect potential problems early and take preventive measures to ensure the safe and efficient operation of the power plant.
