The EHG7305 is 5 Port PoE Unmanaged Gigabit Ethernet Switches designed to work in mission critical environments such as mining and heavy industry. EHG7305 support maximum 5 x 10/100/1000 Base-T(X) RJ45 ports, 1 x 100/1000 Base-F(x) SFP port . With its high performance and non-blocking switching capacity, the EHG7305  is able to fulfill the increasing demand in industrial networking. Its PoE capability of 30W per port up to four ports simplifies the wiring in complex fields, where every cable is an added cost. The equipped terminal block provide dual redundant power inputs with Reverse Polarity Protection and relay output which allows field engineers to build up a fault alarm system. Its IP30 housing protection, wide operating temperature of -40 to 70°C and DIN-Rail mounting capacities are liable to do most industrial field applications.

* 1000 Based-X SFP is only supported in EHG7307.
