Features: Intelligent loop monitoring, real-time reminder, industrial lightning protection 1000A, can work normally in harsh environments such as lightning storms. Gold finger: Gold finger adopts 5mm thick gold plated, reliable contact, low loss, can effectively reduce packet loss rate and data delay. The network connection speed is fast, the transmission rate can reach 1000Mbps. Network Card Interface: external shielded with gold-plated interface, flat contact with internal contact, gold plated 25mm, can effectively reduce contact resistance, improve signal anti-interference, make data transmission smooth. Using imported original chips from Taiwan, the performance is strong, faster and more stable.
