956A7655G03 is a high-reliability avionics data acquisition unit (DAQ), engineered to AS9100D quality standards and RTCA DO-160G environmental specifications, optimized for narrow-body aircraft such as the Boeing 737 MAX and Airbus A320neo during avionics MRO and performance monitoring.

Housed in an EMI-shielded, IP67-sealed aluminum alloy enclosure, it collects and processes real-time data from 32 analog/digital input channels—including sensor readings from engines, hydraulic systems, and flight controls—with ±0.1% measurement accuracy and 1ms data sampling rate. It supports data storage (up to 16GB) and wireless transmission via aviation-grade protocols, with wide-temperature compensation (-55°C to 125°C) and overvoltage protection. Weighing 1.2kg and measuring 115mm×80mm×48mm, it complies with FAA Part 25/EASA CS-25, streamlining diagnostic workflows, reducing MRO downtime, and enhancing flight system safety for commercial fleets.
