Description
The National Instruments SCXI-1303 Isothermal Terminal Block, with part numbers 182380B-02 (Primary) and 777687-03, falls under the SCXI & Legacy category. This model, known as SCXI-1303, is specially designed for high-precision thermocouple temperature measurement applications. The terminal block is compatible with SCXI-1100/1102/1102B/1102C Modules, ensuring a wide range of uses in various setups.
One of the key features of the SCXI-1303 includes a thermistor cold-junction temperature sensor, which is critical for accurate temperature measurements. Additionally, it boasts an isothermal copper plane that helps in maintaining uniform temperature across the block. The open thermocouple detection feature is vital for identifying disconnected thermocouples, ensuring the reliability of measurements. Furthermore, signal ground referencing is provided to minimize noise and ensure accurate readings.
The terminal block comes equipped with 78 screw terminals, facilitating easy and secure connections. The thermistor accuracy is noted to be 0.5 °C within the range of 15 to 35 °C, and 0.9 °C for the temperature ranges of 0 to 15 °C and 35 to 55 °C. This high level of accuracy is essential for precise temperature monitoring and control. The thermistor output ranges from 1.91 to 0.58 V across a temperature range of 0 to 55 °C, providing a wide operating range.
Software compatibility includes NI-DAQ, LabVIEW, and LabWindows/CVI, which allows for flexible and powerful system integration and data analysis. Despite its announced obsolete status by National Instruments, the SCXI-1303 Isothermal Terminal Block remains available for purchase and repairs through Apex Waves, ensuring support for existing systems and applications.
