Description
The NI-9212 is a temperature input module manufactured by National Instruments, falling under their NI C Series product line. This module is specifically designed for temperature measurement applications, making it a crucial component in various industrial and laboratory settings.
It comes in two part numbers, 785259-01 which features a Mini-TC connector, and 782975-01 which comes with a Screw Terminal connector. The measurement accuracy of the NI-9212 varies depending on the connector type; for the Mini-TC connector, the accuracy is approximately 0.71°C, while the Screw Terminal connector offers a slightly higher accuracy of 0.39°C.
One of the key specifications of the NI-9212 is its channel-to-channel isolation. For the Mini-TC connector, the isolation is rated at 60 Vrms, and for the Screw Terminal connector, it’s significantly higher at 250 Vrms. This feature ensures that signals from different channels do not interfere with each other, thus maintaining the integrity of the measurements.
The module is equipped with both Mini-TC and Screw Terminal connector types, providing flexibility in connecting various types of thermocouples. It features 8 isolated thermocouple channels, allowing for simultaneous measurement of temperatures from multiple sources. With a maximum sample rate of 95 S/s/channel, the NI-9212 can achieve a balance between speed and accuracy in temperature data acquisition.
The voltage range of the NI-9212 is ±78.125 mV, and it boasts a high-resolution 24-bit analog to digital converter, ensuring precise temperature measurements. The input impedance is defined as the resistance between COM and TC terminals, which is crucial for accurate temperature readings.
Compatible with LabVIEW software, the NI-9212 integrates seamlessly into National Instruments’ ecosystem, allowing for easy data processing and analysis. Additionally, the module is designed with several notable features, including the ability to be hot-swapped, which facilitates easy replacement without needing to power down the entire system. It also features open thermoc
