 Data Sheet
The NI USB-9211A data acquisition module features integrated signal conditioning that provides plug-and-play connectivity via USB for faster setup and measurements. It is designed especially for thermocouple measurements with 24 bits of resolution for superior accuracy and built-in sensors for cold-junction compensation. In addition, this module includes 250 Vrms channel-to-earth ground isolation for safety, noise immunity, and high common-mode voltage range.
This USB data acquisition module is compatible with Microsoft Windows OSs when using NI-DAQmx driver software, and Mac OS X and Linux OSs when using NI-DAQmx Base driver software. This USB data acquisition module is not compatible with the Traditional NI-DAQ (Legacy) driver.
Every NI USB data acquisition module includes a copy of NI LabVIEW SignalExpress LE for Windows so you can quickly acquire, analyze, and present data without programming. In addition to LabVIEW SignalExpress, USB data acquisition modules are compatible with the following versions (or later) of NI application software – LabVIEW 7.x, LabWindows™/CVI 7.x, or Measurement Studio 7.x; or LabVIEW with the LabVIEW 7.1 Real-Time Module. USB data acquisition modules are also compatible with ANSI C/C++, C#, Visual Studio .NET, and Visual Basic 6.0.
