DS108H
  1.  Industrial 8-port Ethernet Switch for Factory Automation PLC

DS108H, the 8-port 10/100Mbps industrial Ethernet switch, adopting a housing reminiscent of PLC designs, is ideal for Din-Rail installations in automation control cabinets. 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.
