Product Information

Product Description

The EHG7604 series is an Industrial Grade Layer-3 Managed Gigabit Ethernet PoE Switch. It is designed to provide a highly reliable, fault-tolerant, extremely fast network connection in a harsh environment. It is also designed specifically for Automation with Profinet CC-B, MAC-based Black List/White List, IEEE 802.1x, RADIUS, TACACS+, etc., to keep your network safe.

Equipped with two terminal blocks for providing dual redundant power inputs with Reverse Polarity Protection, this switch allows field engineers to build up a stand-alone fault alarm system.

The 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
  • IEEE 802.3af/at complaint PoE RJ45.

The 4-PoE-Port version of the EHG7604 provides up to 120W power budget. Layer-3 Features support IPv4, RIP v1/v2, OSPF v1/v2 and many more.

This switch 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. 

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.
