The UEI-HUMS1 is a powerful Health and Usage Monitoring sys- tems based onUEI’s COTS UEIPAC 800-MIL 8-slot I/O chassis. The unit includes 8 I/O boards selected specifically to match the UH-1N application. The specific I/O boards included in the UEI-HUMS1 are:
All the required software for the above boards is included with the
UEI-HUMS1 and it’s Linux operating system. The unit has been tested to MIL-STD-810 as well as DO-160. It has also been designed
to meet the most commonly required elements of MIL-STD-461,
-704 and -1275 and is sealed to at least IP66/NEMA6 standards.
All this is housed in a compact 17.5” x 8.125” x 7” chassis, weigh-
ing less than 20 pounds and typically consuming less than 40
Watts. 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.
The UEIPAC 1200-MIL chassis on which the UEI-HUMS1 is based is the latest deployment of UEI’s popular DNR-MIL RACKtangle® architecture. However, the UEI-HUMS1 is based on a smaller version that includes 8 slots instead of the UEIPAC 1200’s 12 slots. The smaller size allows the UEI-HUMS1 to be mounted under the UH- 1N’s floor without interfering with the various control rods that extend through the area.
Though the original RACKtangles are quite rugged, the DNR- MIL series takes ruggedness to the extreme. Designed for use in the toughest environments, the new chassis is an ideal solution for military and aerospace deployments. The form factor is also ideal for a huge assortment of commercial applications including use on oil drilling platforms and refineries, heavy machinery, shipboard control, 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 series is identical to the standard DNR Series RACKtangle except for hold-up and protection circuitry added to the power supply inputs. (This power supply conditioning is required in order to meet MIL-STD-1275.) This means the DNR-MIL uses our standard DNR-series board (e.g. DNR-AI-217 or DNR-1553-553).
When deployed the UEI-HUMS1 runs an application on a Linux operating system. This allows unit to both run stand alone con- trol operations as well as running as part of a SCADA system controlled and/or monitored by an external host computer. The VxWorks application in conjunction with the unit’s dual Ethernet ports allows the link to the host PC to be implemented in a fully redundant network.
The DNR-MIL platform is 100% COTS, made in the USA and supported by UEI’s family of over 85 compatible analog, digital and interface I/O boards, including analog inputs up to 24-bits, thermocouples, RTDs, ICP/IEPE, ARINC-429/453/708, MIL-STD-1553, CAN, RVDT/LVDT, synchro/resolver, RS-232/422/485, strain gauge, quadrature encoder, high-voltage analog outputs (up to 115 VDC) with high drive analog output (up to 200 mA), function generator outputs and more.
Whether your application is on a ship/boat, in an aircraft, in a rocket, on an outdoor test cell, on an oil platform or simply going to be left outside and exposed to the elements, the chassis on which the UEI-HUMS1 is based is an ideal solution. Of course if you need fewer I/O, you should consider the 4-slot 4.45” x 6.75” x 7.35” DNA-MIL Cube which offers many of the same features and options, but offers slots for up to 4 I/O boards in a much smaller chassis.
