SIU34-AIUVARM-01

4x 3U OpenVPX MOSA Actuator Interface Unit

SIU34-AIUVARM-01 is a Modular Open Systems Approach (MOSA) DO-178C & DO-254 Certifiable Actuator Interface Units (AIU) with low power high performance OpenVPX Xilinx UltraScale+ SBC with Quad Core ARM Cortex -A53, 8 GB DDR4 SDRAM, 32 GB SATA Flash, 2 x 10/100/1000Base-T Ethernet, USB 3.0, FIPS-140-3 Level 3 Cyber Security, and Single Event Upset support. 

Configured to support dual or tri-redundancy using Serial CCDL or ARINC-429/575 Interfaces. Options for TSN, TTE, AFDX or ARINC664p7 redundancy are also available.

The SIU34-AIUVARM-01 is ideally suited to support several platform flight control systems including fixed-wing aircraft, rotary aircraft, eVTOL and rocket systems. The SIU34-AIUVARM-01 takes advantage of NAI’s COSA Architecture: a flexible, adaptable, configurable, modular and expandable solution that offers an almost infinite number of configurations while eliminating hardware and software NRE redesign. Certifiable RTOS support includes DDC-I Deos 653 and Wind River VxWorks HVP.
