The EHG7504/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, EHG7504/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 EHG7504/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 complaint PoE RJ45. EHG7504/08 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 pttern.
And that’s not all. Designed specifically for Automation, it is Profinet CC-B and Ethernet/IP compatible, MAC-based Black List/ White List, IEEE 802.1x, RADIUS, TACACS+, etc., and keep your network safe.
