Product Description

TH-8G Series is Gigabit Management Industrial Rack-mount Ethernet Switch. The  switch is designed with a fan-less cooling system, which enables it to operate in a wide range of working environments with temperatures ranging from -40℃ to +75℃. With a high protection level and advanced technologies such as lightning protection, this switch boasts excellent industrial quality. It also features integrated switching and security protocols which enhance its stability and security. Additionally, it supports public Ethernet multi-ring protection technology (ERPS recovery time ≤ 15ms) which greatly enhances the networking flexibility and reliability of industrial networks.
