Description
The SCXI-1303, with its NI Part Number 777687-03, is a 32-Channel Isothermal Terminal Block designed for compatibility with National Instruments modules SCXI-1100/1102/1102B/1102C. It is engineered specifically for high-precision thermocouple temperature measurement applications. This terminal block boasts key features such as open thermocouple detection, signal ground referencing, and an isothermal design to ensure reliable and accurate readings.
Equipped with a total of 78 screw terminals, the SCXI-1303 facilitates easy and secure signal connections. The thermistor included in this terminal block offers exceptional accuracy, with a variation of just 0.5 °C between 15 to 35 °C and 0.9 °C between 0 to 15 °C and 35 to 55 °C. It also provides a thermistor output voltage range of 1.91 to 0.58 V over a temperature range of 0 to 55 °C.
For different module requirements, it features interchangeable bias resistors with values of 10 Ω for the SCXI-1100 and 10 MΩ for the SCXI-1102/B/C modules. The device operates using NI-DAQ driver software and is compatible with widely-used software packages such as LabVIEW and LabWindows/CVI. Despite its obsolete status announced by National Instruments, the SCXI-1303 remains available for purchase and repair, ensuring continued support for existing systems.
