Hardware Description
National Instruments USB-9221 is a data acquisition module with
integrated signal conditioning that provides plug-and-play
connectivity via USB for faster setup and measurements. This
module has eight single-ended analog input channels with an
extended input range of ±60 V for direct connection to industrial
sensors. With a maximum single-channel sampling rate of 800 kS/s,
the NI USB-9221 is the fastest device in the USB DAQ with
signal conditioning family. In addition, this module includes
channel-to-earth ground isolation for safety, noise immunity and
high common-mode voltage range. With both screw-terminal and
standard D-Sub connector options for this module, you can obtain
flexible and low-cost signal wiring.
Software Description
The USB-9221 uses NI-DAQmx high-performance, multithreaded
driver software for interactive configuration and data acquisition on
Windows OSs. Use NI-DAQmx to test channels, generate code, and
apply custom scaling to any of your measurements. All NI data
acquisition devices shipped with NI-DAQmx also include VI Logger
Lite configuration-based data-logging software.
Recommended Accessories
The USB-9221 has built-in screw terminals or a D-Sub connector
option that connects to the NI 9934 strain relief accessory, or any
other standard 25-pin D-Sub connector.
Common Applications
The USB-9221 is ideal for high-voltage applications where small size
and portability are essential, such as:
⢠Portable data logging â log voltage data quickly and easily
⢠Academic lab use â obtain academic discounts for quantities
of five or more. Visit ni.com/academic for details.
⢠Industrial testing â take measurements of high-voltage
transformers, batteries, and other electronics
⢠Embedded OEM applications
⢠In-vehicle data acquisition
