Hardware Description

National Instruments USB-9201 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 at 12-bit

resolution and can achieve an aggregate sampling rate of 500 kS/s.

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 D-Sub connector options, the

USB-9201 is designed for flexible and low-cost signal wiring.

Software Description

The

NI

USB-9201

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-9201 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-9201 is ideal for a number of applications where small size

and portability are essential, such as:

• Portable data logging – log voltage data quickly and easily

• Academic lab use – obtain academic discounts for quantities

• Environmental monitoring – monitor environmental conditions

such as humidity or light

• Embedded OEM applications

• In-vehicle data acquisition
