TRENDnet's Industrial Fast Ethernet DIN-Rail Switches feature a rugged IP30 rated metal enclosure. These industrial Ethernet switches are designed to withstand high levels of vibration and shock, operate in both low and high temperatures for industrial environments within a -40deg - 75deg C (-40deg - 167deg F) wide-temperature range. Redundant power inputs with overload current protection on each industrial Ethernet switch minimizes network downtime.
