Product Information

Product Description

Authorized North America Distributor Stamp

The EH7520 20-port switches are a highly reliable and fault-tolerant Industrial Managed Ethernet Switch. There are 16 10/100BASE-T(X) RJ-45 ports and up to 8 PoE ports and optional 4 SFP ports. With their high performance switching capacity, these switches provide a network redundant, self-recovery mechanism that is less than 20ms on a full load. This capability allows you to scheme a reliable Ethernet network by building a redundant ring topology as your back-up solution.

A multifunctional web dashboard 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 management functions that comply with IEC62443 standard.

The EH7520 switches are designed for Industrial rugged applications. They equip a 5-pin terminal block to provide dual redundant power inputs with Reverse Polarity Protection. There are two sets of relays which allow field engineers to build up a stand-alone fault alarm system. Their IP30 housing protection, wide operating temperature of -20 to 70°C and DIN-Rail mounting capacities are able to do most industrial field applications.

Being Profinet CC-B v2.33 certified, these switches are 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.
