Lynx DSS is available in several versions, the L205-S1 is a device server with a layer 3 industrial Ethernet switch, powered by the Westermo WeOS network operating system. Lynx DSS is the most compact and has the lowest power requirements in this class of device servers. Lynx DSS has 4 10/100 Mbit/s ports and one RS-232 port.

Lynx DSS is designed for simple industrial applications, from the robust DIN rail clip solution to the configurable fault contact and the industrial-level dual power inputs.

Only industrial-grade components are used which gives the Lynx DSS an MTBF of 677,000 hours and ensures a long service life. A wide operating temperature range of –40 to +70°C (–40 to +158°F) can be achieved with no moving parts or cooling holes in the case. Lynx DSS has been tested by Westermo and external test houses to meet many EMC, isolation, vibration, and shock standards, all to the highest levels suitable for heavy industrial environments and rail trackside applications.

Westermo has developed WeOS to allow us to offer cross-platform and future-proof solutions. WeOS can deliver unique IP security functionality for this class of product, for instance, a Multiport DMZ can be constructed by utilizing the internal port-based firewall function or Modbus Gateway support. Remote secure access to a network can be provided using encrypted VPNs.

For more WeOS functionality please see the WeOS datasheet.
