Siemens Ruggedcom RS900 Switch


The RUGGEDCOM RS900 is a 9-port utility-grade, fully managed Ethernet switch, specifically designed to operate reliably in electrically harsh and climatically demanding environments. The RS900 provides a high level of immunity to electromagnetic interference and heavy electrical surges typical of environments found on plant floors or in curbside traffic control cabinets. An operating temperature range of –40 to +85°C (–40 to +185°F), together with hazardous location certification (Class 1 Division 2), allows the RS900 to be placed in almost any location.
