TRENDnet's 6-Port Industrial Gigabit PoE+ DIN-Rail Switch, model TI-PG62B, is an industrial variable voltage switch with four gigabit PoE+ ports and a 120W PoE power budget. Users are able to connect four PoE+ devices, and two dedicated SFP slots w/12 Gbps switching capacity to this industrial variable voltage PoE+ switch for high-speed connectivity to the network. The industrial variable voltage PoE+ switch is equipped with a rugged IP30 rated metal enclosure, and designed to withstand a high degree of vibration and shock, while operating within a wide temperature range of -40° - 75° C (-40° - 167° F) for industrial environments. Dual 12 - 55V DC power inputs on the industrial variable voltage switch provide redundancy with power failure alarm relay.
