The industrial AI edge gateway supports the fusion and AI analysis of data from multiple sensors, including vision, vibration, and temperature. Synchronous acquisition of multi-source data requires high-precision time synchronization via IEEE 1588 PTP. With numerous I/O interfaces, a unified EMC protection scheme is necessary. For analog inputs, PBZ1608E600Z0T ferrite beads and TVS P6KE6.8CA are added; for digital inputs, optocoupler isolation and ESD5V0D8B are added; and for PTP network ports, common-mode chokes CMZ2012A-900T and ESDLC3V3D3B are added. Actual measurements show that multi-source data fusion and AI analysis exhibits jitter <1ms under EFT ±2kV.
