North Atlantic SIU34-DCUVARM-01 Data Concentrator Units

Data Concentrator Units (DCU): Data Concentrator Units (DCU) systems often serve as the “central nervous system” for most land, air and sea platforms and host the utilities functions, eliminating several boxes and hundreds of pounds of cable. These Modular Open Systems Approach (MOSA) systems feature an industry leading density of several I/O, measurement, and communication functions. These DCU’s take advantage of NAI’s COSA Architecture, offering 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.

SIU36-DCUVARM-01 is a Modular Open Systems Approach (MOSA) DO-178C & DO-254 Certifiable Data Concentrator Unit (DCU) 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.
