Product Description

The NI SCXI-1327 is a shielded terminal block designed to serve as a connectivity accessory for specific SCXI modules, particularly the SCXI-1102, SCXI-1102C, and SCXI-1102D. It is not a data acquisition module itself but an essential part of the measurement system. This terminal block provides screw terminals for easily and securely connecting a large number of low-voltage sensor wires, such as those from thermocouples, to the SCXI signal conditioning module. Its shielded design helps to protect the signals from noise and interference.

Product Specifications

• Number of Terminals: 50-pin header connector to the SCXI module, with 32 screw terminals for sensor inputs (32 channels, single-ended).
• Sensor Compatibility: Primarily designed for low-voltage sensors like thermocouples and millivolt sources.
• Built-in Features: Includes an onboard cold-junction compensation (CJC) thermistor that is shared with the compatible SCXI-1102C and SCXI-1102D modules for accurate temperature measurements.
• Shielding: The entire terminal block is shielded to minimize noise and improve signal integrity.
• Connection Type: Screw terminals for reliable and robust wiring.

Product Advantages

The SCXI-1327 offers several key advantages when building a measurement system:

• Simplified Wiring: The screw terminal connections make it easy and secure to connect a large number of sensor wires. This is much more reliable and efficient than using bare wires or temporary connections.
• Optimized for Thermocouples: With its built-in CJC thermistor, the terminal block works in tandem with the SCXI-1102 modules to provide highly accurate thermocouple temperature measurements.
• Excellent Noise Immunity: The shielded design provides excellent protection against external electromagnetic interference (EMI), ensuring that your low-level signals remain clean and accurate. This is particularly crucial for sensitive thermocouple and millivolt signals.
• Streamlined Integration: It’s designed to mate seamlessly with its compatible SCXI modules, creating a robust and professional-looking system that is easy to maintain and troubleshoot.

Applications

The SCXI-1327 is used in a wide variety of applications that require multichannel measurement of low-voltage signals, especially temperature. Common uses include:

• Laboratory Automation: Conducting multi-channel temperature monitoring in R&D environments.
• Environmental Monitoring: Collecting temperature data from multiple locations in a process.
• Automotive Testing: Measuring temperatures of engines and other vehicle components using thermocouples.
• Process Control: Monitoring temperature profiles in industrial machinery or processes.

Important Considerations

For optimal performance and reliable operation, keep these points in mind when using the SCXI-1327:

• Module Compatibility: The SCXI-1327 is a specialized accessory and must be used with a compatible SCXI module, such as the SCXI-1102, SCXI-1102C, or SCXI-1102D. It is not compatible with all SCXI modules.
• Proper Wiring: When connecting your sensors, ensure the wiring is neat and secure. Use a screwdriver to firmly fasten the wires to the screw terminals.
• Noise Reduction: For the best results, use shielded sensor cables and ensure the shield is properly grounded. The SCXI-1327’s shielding works best when the entire system is properly grounded.
• Channel Configuration: Be sure to configure the correct channel types in your software (e.g., LabVIEW or NI-DAQmx) to match your physical wiring.
