The product with the part number 182487B-01 (listed) and 777687-03 (actual) falls under the SCXI & Legacy category. It is identified as model SCXI-1303, which is a National Instruments SCXI-1303 Isothermal Terminal Block. This terminal block is specifically designed for high-precision thermocouple temperature measurement applications.
It is compatible with SCXI-1100/1102/1102B/1102C modules, making it a versatile solution for various measurement setups. The SCXI-1303 boasts several outstanding features, including an isothermal copper plane, a thermistor cold-junction sensor for accurate temperature compensation, open thermocouple detection capability to ensure measurement integrity, and signal ground referencing for reduced noise and interference in measurements.
The terminal block has 78 screw terminals and supports 32 differential inputs, catering to a wide range of sensor connection requirements. The thermistor within the SCXI-1303 provides remarkable accuracy, with a deviation of only 0.5 °C within the range of 15 to 35 °C, and 0.9 °C in the colder (0 to 15 °C) and warmer (35 to 55 °C) extremes. The thermistor’s output voltage ranges from 1.91 to 0.58 V across the temperature range of 0 to 55 °C, ensuring reliable temperature readings.
Software compatibility extends to NI-DAQ, LabVIEW, and LabWindows/CVI, providing users with flexibility in data acquisition and analysis. Despite its announced obsolete status by National Instruments, the SCXI-1303 is still available for purchase and repairs through Apex Waves, ensuring continued support for users of this critical measurement equipment.
