Customizable & Deployed Sensor Interface Unit (SIU)
The Navy chose the UEI RACK form factor to replace the obsolete Sensor Interface Unit (SIU) on the Marine Landing Craft LCAC.
Find out why in the Full Story

The UEIOPCUA 400-MIL Cube, an advanced military/aerospace-specified data acquisition and I/O platform housed in a compact 6.2 " x 7.1" x 8.7" chassis, is designed to meet MIL-STD-810 and MIL-STD-461 standards (including all power supply requirements) and supports virtually any input, any sensor and any interface I/O. Designed for use in the toughest environments, this new RACKtangle is also ideal for a huge assortment of commercial applications, including use on oil drilling platforms and refineries, heavy machinery, outdoor test stands and any other I/O application that will be exposed to the elements. All connectivity is through ROHS compliant 38999 connectors.

The ruggedized chassis, weighing 11 pounds and typically consuming less than 40 watts, is easily configured as a stand-alone I/O controller or embedded, programmed and hardened for integration with high density, multifunction data acquisition systems. Its highly advanced architecture provides users with a simple and universal software API to construct, add and reconfigure applications based upon the I/O layers. It is sealed to at least IP66/NEMA6 standards. In addition, no rotary cooling fans are used in the design, which maximizes MTBF and mechanical reliability. All internal printed circuit boards are conformal coated to ensure the highest reliability.


UEI's OPC-UA compatible I/O product family has been designated the UEIOPC-UA series. It offers an unprecedented combination of flexibility, high performance, low cost, ruggedness and small size, all fully supported by your standard OPC-UA client. Based on UEI's popular Cube chassis, the UEIOPCUA 400 allows the installation of up to 4 DNA series I/O boards and is an ideal solution for a great many I/O applications.

UEI-OPC-UA series supports the following profiles and facets:

Server Profile: Embedded UA Server profile

Transport Profile: UA-TCP, UA-SC, UA Binary

Security Profiles: SecurityPolicy - Basic256Sha256, SecurityPolicy - Basic256 and SecurityPolicy - None

Access Types: Data Access, Historical Data Access

System configuration is made easy by the UEI-OPC-UA's intuitive, easy to use web/HTML interface. A screen capture of the web interface is shown below. The web interface also supports the OPC-UA Historian functionality.

There are currently over 90 different I/O boards available providing the functions listed below:


UEI's OPC-UA web based I/O configuration tool makes it very easy to configure your system and prepare it to connect to your OPCUA server.

Input Boards

  • 0-20 / 4-20 mA input
  • Thermocouple input
  • RTD input
  • Strain and Wheatstone Bridge input
  • Voltage input
  • Digital I/O
  • Speed/Frequency Input
  • Quadrature Encoder Input

Output Boards

  • 0-20 / 4-20 mA output
  • Voltage Output
  • Digital Output
  • Relay Output
  • Plus many more

With this many different I/O boards available, there is sure to be a configuration perfect for your application.

The UEIOPC-UA 400 has been tested at 5g Vibration and 100g Shock. Its small footprint and ability to survive harsh mechanical stress makes it a perfect solution in many industrial applications. No longer dependent upon Windows, our OPC chassis are standalone OPC servers. OPC-UA systems are ideal solutions in a wide variety of measurement and control applications in industries such as: Oil & Gas, Automotive, Energy Systems, Food & Beverage, Water Treatment, Chemical Processing and many more!

Additional information on UEI and OPC-UA can be found in our Software Support section.

The RACKtangle chassis is available in different deployment options including: PowerDNA, PAC (Programmable Automation Controller), Simulink/RTW Target, Modbus TCP Interface and OPC Unified Architecture Interface.
