National Instruments NI-9221 C Series Voltage Input Module

The NI‑9221 (Part Numbers: 779373-01, 783732-01, 779014-01, and 779373-02) is a C Series Voltage Input Module created by National Instruments that accomplishes single-ended analog input and comes with -60 V to 60 V analog input voltage range, 800 kS/s maximum sample rate, 12 Bit resolution, and 8 single-ended analog input channels. The only variation in the different part numbers for this module is the connector type. All other specifications are the same. This module does not have any differential analog input channels. The more extensive voltage area makes this module appropriate for industries, vehicles, or significantly smaller cell battery estimations. This module does not have simultaneous sampling. Each version of the NI 9221 module is enclosed and supports both the CompactDAQ and CompactRIO hardware platforms.

There are two connector choices for the NI 9221 C Series Voltage Input Module. The first type of connector is a 10-position screw-terminal connector for explicit connectedness. The second connector type is a 25-position D-Sub connector. There is also a spring terminal connector type available. The business standard 25-position D-Sub connector gives non-expensive cabling to a huge assortment of embellishments accessible from NI or different sellers. A few merchants additionally offer custom D-Sub link creation benefits and furnish links with a pinout that concatenate the user’s specific application needs. NI suggests the NI 9932 strain-alleviation connector extra for the National Instruments cRIO-9221 simple information module.

The NI 9221 is run using the NI-DAQ driver software which is compatible with software packages/application development environments (ADEs) such as LabVIEW, LabWindows/CVI, C/C++, C#, or Visual Basic .NET. The device has a power consumption value of 1 W maximum when active, and 1 mW max when in sleep mode.

The D-SUB fitted model of the device weighs 5.0 oz, while its counterparts – the spring terminal and screw terminal fitted models weigh 5.4 oz and 5.8 oz respectively. The device has a recommended operating temperature range of -40 °C to 70 °C, and a storage temperature range of -40 °C to 85 °C. Other NI 9221 specifications can be located on the product page for the module under the technical specifications section.

The NI‑9221 is available to be calibrated. While the recommended calibration period for individual parts varies, most parts should be calibrated either annually or every two years to ensure accuracy. If you need the NI‑9221 calibrated, Apex Waves provides options. We offer high-quality NIST accredited calibrations through a 3rd party, with an average turnaround time of 1 to 2 weeks. When you order the NI‑9221 with us, you can request basic (unaccredited) in-house calibration that will calibrate the part to the manufacturer specifications prior to being shipped.
