UEI collects real-world data for the Aerospace, Energy and Defense industries allowing our customers to build smart systems that are reliable, flexible and rugged...

We set the benchmark in the PC/Ethernet data acquisition (DAQ) and control, data logger/recorder and programmable automation controller (PAC) and modbus TCP markets. Founded in 1990, our first products were ISA bus DAQ boards. PCI andPXI boards were added in the mid 90s and continueas an important part of our product offering today.In 2004, UEI introduced the revolutionary PowerDNA® Cube and more recentlywe released our RACKtangle® (designated by "DNR") and FLATRACK™ (designated by "DNF") chassis, as well as GigE versions of the Cube. PowerDNA (Distributed Network Architecture) is UEI's series of chassis that act as I/O slaves to a host PC.They perform the tasks the host commands. The PowerDNA configuration works well in both data acquisition and control applications.

UEI’s compact and rugged chassis are ideally suited for awide variety of industrial, military, aerospace, energy, laboratory DAQ and control applications. Each Cube and Rack chassis includes aCPU, real-time OS, Ethernet interface and slots allowing the installation of I/O boards. All our boards are compatible with all of our chassisoptions. With more than 85 I/O boards available, we’re sure to have just what you need. UEI supports all popular Windows, Linux, VxWorks and Realtime operating systems. Our software suite provides a simple, universal API and supports all common programming languages. Our Cube and Rack chassis fully support an extensive array of application packages including LabVIEW™, MATLAB®, Simulink® and more.

UEI holds a number of patents, including a patenton a UDP protocol that allows real-time monitoring and control of our PowerDNA cubes overEthernet.

UEI has the world’s widest selection of simultaneously sampling A/D boards and the world's most dense analog output boards -- up to 96 channels per slot!

UEI’s Calibration laboratory is now certified to: ISO / IEC 17025:2005.

UEI is ROHS (ROHS2) compliant.

UEI is REACH (Registration, Evaluation and Authorization of Chemical Substances –EC1907/2006) compliant.

Our products have received numerous awards including Test and Measurement World’s “Best in Test." All UEI products are developed and manufactured in the United States.

In 2017, United Electronics Industries GmbH opened offices in Hamburg, Germany! Contact the UEI GmbH sales office at +49-171-9458385 or
