Description
The National Instruments NI-9221 C Series Voltage Input Module, with part numbers 779373-01, 783732-01, 779014-01, and 779373-02, falls under the category of C Series Analog Input. This module is designed for applications requiring high-precision voltage measurements. It supports single-ended analog input and can handle an input voltage range from -60 V to 60 V.
One of the key features of the NI-9221 is its impressive maximum sample rate of 800 kS/s, paired with a resolution of 12 Bit. This allows for accurate and fast data acquisition. The module is equipped with 8 single-ended analog input channels, making it versatile for various measurement tasks.
For connectivity, it offers several options including a 10-position screw-terminal, 25-position D-Sub, and Spring terminal. These options provide flexibility in connecting to a wide range of sensors and signals. The NI-9221 is compatible with CompactDAQ and CompactRIO systems, ensuring easy integration into existing setups.
Software compatibility is extensive, supporting LabVIEW, LabWindows/CVI, C/C++, C#, and Visual Basic .NET. This ensures that developers can use the programming environment they are most comfortable with or best suits their application requirements.
In terms of power consumption, the module is efficient with a maximum of 1 W in active mode and goes down to 1 mW in sleep mode, highlighting its suitability for low-power applications. The weights vary depending on the model, with the D-SUB model weighing 5.0 oz, the Spring terminal model at 5.4 oz, and the Screw terminal model being the heaviest at 5.8 oz.
