Description
The National Instruments NI-9212 is a high-quality C Series Temperature Input Module designed for precision temperature measurement. This module is compatible with both CompactDAQ and CompactRIO platforms, making it a versatile choice for various applications.
The NI-9212 is available in two part numbers, 785259-01 and 782975-01, each with its own unique specifications. For instance, the measurement accuracy of part 785259-01 is 0.71°C, whereas for part 782975-01, it is significantly higher at 0.39°C. This difference in accuracy ensures that users can select the module that best fits their precision requirements.
When it comes to safety and signal integrity, the module offers different levels of channel-to-channel isolation: 60 Vrms for part 785259-01 and 250 Vrms for part 782975-01. Such isolation levels provide robust protection against high voltage transients and ensure accurate data capture across channels.
Furthermore, the NI-9212 accommodates diverse connection needs with its two front connector types. The Mini-TC connector is provided with part 785259-01, while part 782975-01 features a Screw Terminal connector. This flexibility allows for easy integration with various thermocouple types and wiring configurations.
Equipped with 8 Isolated Thermocouple Channels, this module can simultaneously measure temperatures from multiple sources at a maximum sample rate of 95 S/s/channel. The high sample rate, coupled with a ±78.125 mV maximum voltage range, ensures accurate and fast temperature readings across a broad range of conditions.
Software compatibility with LabVIEW offers an intuitive and powerful environment for programming and data visualization, further enhancing the module’s usability. The NI-9212 also boasts an analog to digital converter resolution of 24 bit, providing high-resolution temperature data for precise control and monitoring tasks.
In terms of design, the module is hot-swappable, supports open thermocouple
