Key Features: 


Precise Sensor Measurements

Pick from more than 70 high-quality C Series I/O modules with built-in sensor- or signal-specific conditioning. Mix and match to build an accurate and repeatable system that meets any measurement needs.


System Scalability

Expand and distribute your system with Ethernet-compatible CompactDAQ chassis to take µs-synchronized measurements across multiple chassis and in distributed setups.


Compact, Rugged Design

Move with ease between lab and field with CompactDAQ’s rugged features, designed to withstand operating temperatures from -40 °C to 70 °C and up to 30 g of shock. Expand to extreme environments with IP67-rated FieldDAQTM devices.


Develop or Don’t

Develop a custom data- logging application with .NET, C#, Python, or LabVIEW, or use FlexLogger™ application software to quickly configure your system and log and view data.

Why Choose CompactDAQ?

CompactDAQ is a cost-effective approach to benchtop measurement. Pair sensor-specific, conditioned I/O modules with software optimized for DAQ applications.


Best for

  • High-channel-count distributed DAQ applications 

  • Benchtop test and measurement 

  • Mixed sensor measurements 


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.

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.



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.



With more than 60 C Series I/O modules for nearly any sensor type, quickly design a custom hardware setup optimized for size, cost, and performance. C Series modules are high-quality input and output modules that provide signal conditioning and analog-to-digital conversion for your CompactDAQ system. These hot-swappable modules plug directly into your chassis, making it simple to build a system tailored for your specific test requirements.
