Unmanaged Industrial Ethernet Switch_480px_SDI-880

The SDI-880 is a simple and cost effective industrial unmanaged  Industrial ethernet switch suitable for use in a wide range of factory and building automation applications. A high speed switch core ensures full speed on all ports and transparency to any Ethernet protocol.

The unit is designed for DIN rail mounting into industrial cabinets allowing simple Ethernet connections to be established between PLCs, I/O units, drives, inverters and HMIs. The dual power input makes the unit ideal in these types of application and the fault relay can be connected to an I/O unit to provide simple network management.

Designed to work in industrial environments with its IP 31 Aluminium housing and a wide temperature specification the westermo Industrial Ethernet Switch SDI-880 is an ideal automation solution.

The Unmanaged Industrial Ethernet Switch SDI-880 is so easy to use, simply connect power to the screw terminals and plug in your RJ-45 cables. If you plan to use the fault contacts a DIP switch allows configuration whilst LEDs provide simple diagnostics if required. A broadcast storm filter even helps out if a loop is created by mistake.
