Managed Industrial Ethernet Switch – L206 S2

Managed Industrial Ethernet Switch _480px_lx06-s2

Lynx DSS is available in several versions, the L206-S2 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 two serial ports. One of the serial ports is configured for RS-232 the other one can be configured for RS-232 or RS-422/485

Lynx DSS is managed industrial ethernet switch designed for simple use in 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 499.000 hours and ensures a long service life. A wide operating temperature range –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 both 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 application.

WeOS has been developed by Westermo 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 utilising the internal port based firewall function or Modbus Gateway support. Remote secure access to a network can be provided using encrypted VPNs.
