Description
The National Instruments NI-9212 is a premium module categorized under the C Series Analog Input modules. It is specifically designed to cater to a wide range of applications including in-vehicle data logging, battery stack testing, and white goods testing. This module features 8 isolated thermocouple channels, making it an ideal choice for sophisticated measurement tasks.
When it comes to measurement accuracy, the NI-9212 offers two versions with distinct accuracies: one version (part number 785259-01) provides an accuracy of 0.71 degrees C, while the other version (part number 782975-01) offers a superior accuracy of 0.39 degrees C. This ensures precise measurements for critical applications.
Channel-to-channel isolation is another significant specification of the NI-9212. The module with part number 785259-01 offers an isolation of 60 Vrms, whereas the version with part number 782975-01 provides a higher isolation level of 250 Vrms. This feature is crucial for safety and accuracy in measurements involving high voltage levels.
The NI-9212 is equipped with two types of front connectors: the Mini-TC connector for part number 785259-01 and the Screw Terminal for part number 782975-01. This flexibility allows for easy and secure connections depending on the specific requirements of the application.
Compatibility with CompactDAQ and CompactRIO platforms is a key feature of the NI-9212, ensuring seamless integration into existing setups. This module is also compatible with LabVIEW software, offering a comprehensive environment for developing measurement and control systems.
The module boasts a maximum sample rate of 95 S/s per channel, enabling fast data acquisition for dynamic testing scenarios. Additionally, the NI-9212 supports hot-swapping, allowing users to replace modules without shutting down the entire system, thereby minimizing downtime.
The maximum voltage range of ±78.125 mV, combined with an analog to digital converter resolution of 24 bit, ensures high fidelity measurements. The module also features open thermocouple detection, which is vital for identifying disconnected thermocouples, ensuring the reliability of the measurement data.
Furthermore, each channel of the NI-9212 includes a resistor between the COM and TC terminals, providing a defined input impedance that enhances measurement accuracy and stability. The module also supports high-speed timing mode, expanding its utility
