Features: The imported original strong chip makes the speed faster and more stable. Smart loop monitoring, real-time reminder, more convenient and safer. Industrial lightning protection 1000A, no fear of lightning storms and other harsh environments. The external interface of the network card adopts a fully shielded gold-plated interface. The internal contact adopts a flat needle and is gold-plated 25mm. It can effectively reduce the contact resistance, improve the signal anti-interference, and make the data transmission smooth. Gold finger 5mm thick gold plating, reliable contact loss, can effectively reduce lost packets and data delay.
