EH7520 Series

Industrial PoE Managed Switches

  • Up to 16 10/100 BASE-T(X) ports and 4 10/100/1000 BASE-T(X) Combo ports
  • Up to 8 802.3af or 802.3at complaint PoE ports
  • ERPS Ring (recovery time < 20ms @ 40 switches), STP/RSTP/MSTP for network redundancy
  • Remote management over Web browser, Telnet console, serial console, and Windows Utility
  • Profinet CC-B v2.33 certified and GSDML file provided
  • Security features based on IEC62443-4-2

The EH7520 Series is a highly reliable and fault-tolerant Industrial 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 redundant 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. To prevent network intrusions, it is necessary to have a good accessing control mechanism that can identify, authenticate and authorize users. EH7520 supports user account, password policy, and authentication interface managements functions that comply with IEC62443 standard.

The EH7520 Series is designed for Industrial rugged applications. It equips a 5-pins terminal block to provide dual redundant 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 applications.

Being Profinet CC-B v2.33 certified, this switch Series is Automation and IoT ready. Profinet allows wired and wireless combinations for an array of connectivity options, providing a more effective backbone for your automation operations.
