956A7644G02 is a mission-critical avionics data acquisition unit (DAU), engineered to AS9100D quality benchmarks and RTCA DO-160G environmental standards, optimized for narrow-body aircraft like the Boeing 737 MAX and Airbus A320neo during MRO and avionics system upgrades.

Housed in an EMI-shielded aluminum enclosure with an IP67 hermetic seal, it collects and processes real-time data from 32 analog/digital sensors (including pressure, temperature, and voltage transducers) across aircraft systems, supporting ARINC 429 and CAN bus protocols with <2ms latency and 99.999% data integrity. It features wide-temperature compensation (-55°C to 125°C), redundant power paths, and built-in diagnostic tools, weighing 0.92 kg and measuring 105mm×72mm×40mm. Compliant with FAA Part 25/EASA CS-25, it streamlines system troubleshooting and enhances flight data visibility for MRO teams, reducing aircraft on-ground time.
