INTRODUCTION

      • The EHG7604 Series is an Industrial Grade Layer-3 Managed Gigabit Ethernet PoE Switch. Designed to provide a highly reliable, fault-tolerant, extremely fast network connection in a harsh environment, EHG7604 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. EHG76XX 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 EHG7604 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. EHG7604 provide, in its 4-PoE-Port Version, up to 120W power budget. Layer-3 Features support IPv4, RIP v1/v2, OSPF v1/v2 and many more.
      • 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 (Manager/ Client) redundancy. And that’s not all. Designed specifically for Automation, it is Profinet CC-B, MAC-based Black List/White List, IEEE 802.1x, RADIUS, TACACS+, etc., and keep your network safe.
      • Automation and IoT ready: Conforming with Profinet CC-B v2.33 makes EHG76XX the perfect candidate for being the backbone of your Industrial automation.
      • EN50155 and EN50121-4 Certified: 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.
