Is the industrial AI edge gateway compatible with bidirectional data interaction of the OPC UA/DA protocol?

Time：2025-12-06 Views：508次

Share：

The industrial AI edge gateway integrates an OPC UA server to achieve data interaction. OPC UA Ethernet communication needs to withstand a 1kV surge protection scheme. A common-mode choke CMZ2012A-900T and a TVS ESDLC3V3D3B transformer center tap are connected in parallel on the RJ45 side, with a 1nF 2kV capacitor connected to signal ground. Simultaneously, the PHY power supply uses a PBZ1608E600Z0T ferrite bead to isolate noise. An ESD5V 0D8B clamp is applied to the OPC UA client command input DI interface for electrostatic discharge. Under a measured surge of ±2kV, the OPC UA session remains uninterrupted, with a data refresh rate of 50ms.
