Remote Interface Unit/Data Concentrator

The A175 is a rugged, self-contained, EMC/EMI-protected remote interface unit (RIU) I/O expansion sub-system that provides dynamic mission profile reprogramming. It can recognize its physical location within the platform and communicate with the main mission computer, allowing the unit to alter its functionality ‘on-the-fly’ or at power up. 

Also classified as a data concentrator unit (DCU), the A175 optimizes SWaP with dimensions of only 7” x 7” x 1.3” (178 mm x 178 mm x 33 mm) and a weight of less than 2.5 lb (11.3 kg), while drawing only 10 W.

Applications include manned and unmanned vehicles such as wheeled, tracked ground units as well as tactical fixed and rotary wing aircraft. In addition, above and below deck implementations on naval surface ships as well as subsurface naval ships benefit from this reliable MIL-STD sub-system.
