DS408H
  1.  Industrial 8-port Managed Gigabit Ethernet Switch with 2 Gigabit SFP

DS408H, the 8-port Managed Gigabit industrial Ethernet switch, adopting a housing reminiscent of PLC designs, is ideal for Din-Rail installations in automation control cabinets with 2 port Gigabit Fiber communication. Engineered to withstand harsh conditions, the protection level of DS408H aligns with heavy industrial communication standards, with support for both low voltage 11~ 27Vac and wide range 10~36V DC power inputs, while enduring wide temperatures from -40~75 ℃. Additionally, it incorporates most of L2 features, ERPS, RSTP, IGMP/Snooping, QoS,VLAN, SNMP and WEB UI management features to ensure optimal network performance. The switch forwarding mechanism, enables seamless communication for a wider range of industrial protocols for automation control systems. Engineered to withstand harsh conditions, the protection level of DS108H aligns with railway communication standards, with support for both low voltage 9V to 27Vac and wide range 10V to 36V DC power inputs, while enduring wide temperatures from -40~75 ℃. Additionally, it incorporates broadcast storm filtering, Quality of Service (QoS), and Port-Based VLAN features to ensure optimal network performance. The switch forwarding mechanism, enables seamless communication for a wider range of industrial protocols such as Profit-Net, Ethernet/IP, and Modbus/TCP, essential for automation control systems.
