What is CompactDAQ?

compactdaq systems are composed of compactdaq chassis, compactdaq modules, and software like daq express, flexlogger, or labview

CompactDAQ systems collect and deliver the data validation you need to meet test requirements at any distance, in any environment. These portable, customizable solutions—made of data acquisition modules that can synchronize measurements across a network—help you digitize data closer to sensors, minimizing noise and simplifying cabling in the field.

CompactDAQ System Components

In a CompactDAQ system, a chassis is connected to your PC through USB or Ethernet, and then populated with one or more conditioned I/O modules for direct sensor connectivity. Controller variants are available to run a Windows or real-time OS for stand-alone operation.







ni compactdaq chassis are designed for extreme environments

Built for accurate, conditioned measurements, you can use CompactDAQ chassis to perform mixed-measurement data acquisition all within one synchronized I/O system. CompactDAQ chassis feature USB or Ethernet connectivity and are available with different slot counts to provide the right amount of I/O for various applications. You can pair your system with the right software to customize how you acquire, analyze, present, and manage your measurement data.


compactdaq controllers perform waveform acquisition and inline software analysis

The CompactDAQ controller is a rugged, reliable, high-performance integrated controller with industry-standard certifications. It’s ideal for performing waveform acquisition and inline software analysis while logging data to onboard or removable SD memory. The controller also offers a wide array of standard connectivity and expansion options, such as USB, Ethernet, CAN/LIN, and RS232 serial.
