The EHG7508 Series is an Industrial Grade Managed Gigabit Ethernet PoE Switch. Designed to provide a highly reliable, fault-tolerant, extremely fast network connection in a harsh environment, EHG7508 Series equips two terminal blocks to provide dual redundant power inputs with Reverse Polarity Protection and allows field engineers to build up a stand-alone fault alarm system. EHG75XX family is UL, CE, FCC and NEMA TS-2 certified, allowing the use in Traffic Control Applications.

Within its compact DIN-Rail housing design, the EHG7508 series allows you to choose between different port combinations: 10/100/1000 BASE-T(X) RJ45 port, 1000 BASE-X SFP port and IEEE 802.3af/at compliant PoE RJ45. EHG7508 provide, in its 8-PoE-Port Version, up to 240W power budget.

This is the right choice if you want to set up a reliable network environment with its intelligent features and keep equipment connected all the time, even in case of temporary network breakdowns through RSTP, ERPS Rings and MRP (client) redundancy. Being multiple Compatible Rings also supported, ATOP can be the best choice to have a painless enhancement of an existing infrastructure that doesn’t jeopardize network Topology and existing working pattern. To prevent network intrusions, it is necessary to have a good accessing control mechanism that can identify, authenticate and authorize users. EHG7508 support user account, password policy, and authentication interface managements functions that comply with IEC62443 standard.

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.

Having undergone environmental testing to ensure reliable performance under a variety of power supply conditions, such as voltage variations, power interruptions, and supply changeovers, this switch Series is fully EN50155-certified for today’s demanding railway applications, as well as complying with essential sections of EN50121-4 for ground equipment.
