Description
The part number 777687-03 refers to a product in the SCXI & Legacy category, specifically the model SCXI-1303. This model is described as a 32 ch Isothermal Terminal Block, designed primarily for high-precision thermocouple temperature measurement applications. It is compatible with several modules, including SCXI-1100/1102/1102B/1102C.
One of the key features of the SCXI-1303 includes a precise thermistor cold-junction sensor, an isothermal copper plane, open thermocouple detection, signal ground referencing, and both pullup and bias resistors. The unit is equipped with 78 screw terminals to facilitate connections.
The thermistor’s accuracy is rated at 0.5 °C (15 to 35 °C) and 0.9 °C (0 to 15 °C and 35 to 55 °C), with an output range from 1.91 to 0.58 V (0 to 55 °C). For software integration, it is compatible with NI-DAQ, LabVIEW, and LabWindows/CVI, ensuring versatility in use.
Although it has been announced as obsolete by National Instruments, it remains available at Apex Waves. Calibration services are also available, being NIST accredited through a 3rd party, with an average turnaround of 1 to 2 weeks.
