Rugged, Mil/Aero style 6-slot I/O chassis

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.

The DNR-MIL-6 is the latest deployment of UEI’s popular RACKtangle® architecture. It is basically a smaller version of UEI’s popular DNR-MIL, and offers slots for six I/O boards rather than the DNR-MIL’s twelve. Designed for use in the toughest environments, the DNR-MIL-6 is ideal for military and aerospace deployments. It is also ideal for a huge assortment of commercial applications, including 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.

Electronically, the DNR-MIL-6 is identical to the standard DNR Series RACKtangle, except for hold-up and protection circuitry on the power supply inputs to meet MIL-STD-1275/704.) This means the DNR-MIL-6 uses standard DNR-series boards (e.g. DNR-AI-217 or DNR-1553-553). With over 80 unique I/O boards and 6 slots available, there’s sure to be a configuration matching your application.

The new DNR-MIL-6 is designed to meet the most commonly required elements of MIL-STD-461 and -810 and is sealed to at least IP66/NEMA6 standards. All this is housed in a compact 11.6" (wide) x 7.0" (tall) x 6.4" (deep) chassis, weighing approximately 16 pounds and typically consuming less than 30 Watts. Heat transfer from the internal electronics to the external chassis is designed such that no fans or rotary cooling is required. The lack of fans maximizes MTBF and mechanical reliability. All internal printed circuit boards are conformal coated to ensure the highest reliability. Heat sink style fins on the top and bottom of the unit ensure the unit will meet its temperature specifications without any forced air cooling, though the unit is also suitable for use with a cold plate if appropriate.

Software supported by the DNR-MIL-6 includes Windows, Linux, VxWorks, QNX, RTX and more, as seen in our Software Support section.

The DNR-MIL-6 is available in different deployment options, including: PowerDNA, PAC (Programmable Automation Controller), Simulink Coder, Modbus TCP Interface and OPC Unified Architecture Interface.
