The EH7520 Series is a highly reliable and fault-tolerant Indus- trial Managed PoE Ethernet Switch. It equips up to sixteen 10/100BASE-T(X) RJ-45 ports and up to four 10/100/1000BASE- T(X)/FX RJ-45 and SFP ports. With its high performance switching capacity, EH7520 Series provides network redun- dant self-recovery mechanism is less than 20ms on full load which allows you to scheme a reliable Ethernet network by building a redundant ring topology as your back-up solution. With a Multifunctional web dashboard, EH7520 Series offers intelligent features such as Quality of service (QoS), Virtual LAN (VLAN), IGMP, Port mirroring and security. 

The EH7520 Series is designed for Industrial rugged applica- tions. It equips a 5-pins terminal block to provide dual redun- dant power inputs with Reverse Polarity Protection and two sets of relay which allows field engineers to build up a stand-alone fault alarm system. Its IP30 housing protection, wide operating temperature of -20 to 70°C and DIN-Rail mounting capacities are liable to do most industrial filed
