Ethernet I/O DAQ and Programmable Automation Controller PAC

General Description: 

The PowerDNA (Distributed Networked Automation) Cube, DNR RACKtangles and DNF FLATRACKS and MIL series and UEINet chassis are compact, rugged, Ethernet-based data acquisition and control chassis. Programs and applications running on a host PC receive data from input (or I/O) boards within the chassis and write data to output channels. I/O boards may be installed in any combination, allowing the Cubes/RACKs to be precisely matched to your system requirements. With over 60 different I/O boards available, there is sure to be a perfect solution for your application. DNA series Cubes and DNR/DNF series RACKS are ideally suited for a wide variety of simulation, industrial, aerospace, and laboratory DAQ and control applications.

PowerDNA Cubes and UEINet chassis

DNA series Cubes and UEINet chassis are smaller, and more rugged than the various RACK alternatives. The Cube and UEINet are also an ideal OEM form factor as it is easy to embed them inside your product. The standard 100Base-T Cubes are also somewhat more rugged than the RACKs and are rated from -40 °C to +85 °C, at 5 g vibration and up to 100 g shock. Special versions have even been tested to altitudes of greater than 120,000 feet. The GigE cubes and DNR and DNF series RACK chassis are rated from -40 °C to +70 °C, 3 g vibration and 100 g shock.

UEI’s hardware can be deployed in several hosted and/or standalone configurations. Our systems can operate as I/O slaves under control of a host PC and may also run as fully standalone data loggers or embedded controllers.  Alternatively, they can operate as a hybrid, running applications locally, but taking direction from, or sharing data with a host PC on the network.


PowerDNA (Distributed Network Architecture):  UEI’s PowerDNA mode comprises hosted systems that support all popular operating systems including Windows, Linux, QNX, VxWorks and more. PowerDNA systems can be programmed with UEI‘s framework (UEIDAQ), which uses a single, simple and universal API that supports all programming languages. Our PowerDNA series chassis act as I/O slaves to a host PC, executing tasks under host commands. This configuration works well in both data acquisition and control applications.

UEI offers extensive drivers and support for Linux and other popular Real-time Operating Systems, including QNX, INtime, and VxWorks. Our drivers are factory developed and supported in house. Though many DAQ firms have ignored the Linux/RTOS market, or relegated their support to unofficial user forums, UEI provides complete drivers for our data acquisition hardware, and in this way, offer our customers factory support. All Linux drivers as well as those for most RTOS are included with the product and are available for download on our web site. There is a small charge for QNX and VxWorks drivers.

UEIPAC (Programmable Automation Controller):  UEIPAC is an ideal solution for systems requiring a small, standalone embedded controller or data logger. The PAC runs a standard Linux or VxWorks operating system. Once developed, application code is compiled and downloaded to the UEIPAC. From there the UEIPAC system can run fully standalone, or you may keep the UEIPAC on your network to provide updates to your host. The UEIPAC is also frequently used as a local control node tied to a host PC. In this mode, the UEIPAC executes the local applications as directed by the host. UEI also offers Xenomai extension for Linux on the UEIPAC. The UEIPAC provides remarkable performance, flexibility and power all in a compact chassis. 


Though most customers consider UEI a “hardware” company, we never underestimate the value of software/programming in our products. Our goal is to provide you with the software/programming support you need, regardless of what language, application or operating system you wish to use. Whether you’re programing in C/C++, VB, any of the .NET languages or in applications such as NI LabVIEW and MATLAB, our support is unparalleled in the industry. 

UEI supports many of today’s popular application packages.  We realize that there are a variety of protocols available to communicate with and acquire data, as well as to manage multi-faceted control systems, so we offer the application support necessary for you to be successful. This includes support for Modbus, EPICS, OPC-UA and many of the emerging IoT (Internet of Things) technologies. Below, please find a breakout of popular OSs, programming languages and applications UEI supports
