Aitech Announced A175 RIU Subsystem for More System Profiles Applications

Aitech Defense Systems Inc. has introduced the A175 self-contained, EMC/EMI-protected Remote Interface Unit (RIU) I/O expansion subsystem that provides on-the-fly mission profile reprogramming. The subsystem adopts platform location monitoring built into the on-board FPGA to spot its physical location within the platform and communicate with the main mission computer, making the unit to change its functionality ’on-the-fly’ or at power up. Also classified as a data concentrator unit (DCU), the A175 develops SWaP (size, weight and power) with dimensions of 7" x 7" x 1.3" and a weight of less than 2.5 lbs (the approximate weight of one 6U conduction-cooled VMEbus board), while drawing 10 W, or about the same as a standard household incandescent nightlight. The devices are used in manned and unmanned vehicles such as wheeled, tracked ground units as well as tactical fixed and rotary wing aircraft.

The A175 is useful in highly data centric environments such as a remote interface data concentrator or engine and power train data monitor as well as in vehicle prognostics data collection and condition based maintenance (CBM).

The A175’s expansive I/O includes dual platform data channels for connection to the aircraft main bus with either dual GbE channels or one dual redundant MIL-STD-1553B channel. There are also two asynchronous RS232/485 serial ports, eight single ended 12-bit A/D input channels, up to eight ARINC-429 drivers/receivers, two differential 16-bit D/A output channels and four differential channels with an external or internal reference voltage.

The device also can be an internal elapsed time data recorder and internal temperature sensor for high integrity, mission critical subsystems. Units have been qualified for manned aircraft use with added gunfire vibration and high shock.

The temperature of the A175 is from -40°C to +71°C with natural convection cooling and is powered from a standard 28 VDC input per MIL-STD-740D. In addition to EMI protection, endurance against shock, vibration and acceleration per MIL-STD 810F as well as extreme resistance to altitude, humidity and temperature are ensured by the subsystem’s rugged Faraday cage design.
