Actuator Interface Units (AIU): Actuator Interface Units (AIU) systems serve as a focal point in tying a wide variety of sensors together that indicate temperature, flow, level or pressure. These Modular Open Systems Approach (MOSA) systems feature different analog and digital input and output modules that can be used with a wide range of function types including AC excitation, LVDT, variable reluctance, thermocouples, and RTDs. NAI’s rugged AIU systems offer a DO-178C & DO-254 Certifiable solution and are ruggedized to withstand -40° C to +71° C and qualified to MIL-STD-1275D & MIL-STD-704A with 50 ms holdup (power supply); MIL-STD-461F & MIL-STD-810G.
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.
