Product Information

Product Description

Authorized North America Distributor Stamp

The EHG7508 Series is an Industrial Grade Managed Gigabit Ethernet Switch and has a PoE option. Designed to provide a highly reliable, fault-tolerant, extremely fast network connection in a harsh environment, there are 2 terminal blocks to provide dual redundant power inputs with Reverse Polarity Protection; it also allows field engineers to build up a stand-alone fault alarm system.

These switches are UL, CE, FCC and NEMA TS-2 certified, allowing them to be used in Traffic Control Applications. They are fully EN50155-certified for today’s demanding railway applications, as well as complying with essential sections of EN50121-4 for ground equipment.

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
  • IEEE 802.3af/at compliant PoE RJ45 port provides up to 240W power.

These switches are designed for setting up a reliable network environment with intelligent features and keeping equipment connected all the time, even in case of temporary network breakdowns through RSTP, ERPS Rings and MRP (client) redundancy.

Supporting multiple Compatible Rings, these switches are the best choice for painless enhancement of an existing infrastructure that doesn’t jeopardize network Topology and existing working pattern. To prevent network intrusions, there is a good accessing control mechanism that can identify, authenticate and authorize users.

User account, password policy, and authentication interface management functions comply with the IEC62443 standard are supported.

Being Profinet CC-B v2.33 certified, these switches are Automation and IoT ready. Profinet allows wired combinations for an array of connectivity options, providing a more effective backbone for your automation operations.
