The ATOP EHG7508 is an 8-port Industrial Grade Managed Gigabit Ethernet Switch. Designed to provide a highly reliable, fault-tolerant, extremely fast network connection in a harsh environment, the EHG7508 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. The EHG7508 is UL, CE, FCC and NEMA TS-2 certified, allowing the use in Traffic Control Applications.

To prevent network intrusions, it is necessary to have a good accessing control mechanism that can identify, authenticate and authorize users. The ATOP EHG7508 support user account, password policy, and authentication interface managements functions that comply with IEC62443 standard. Having undergone environmental testing to ensure reliable performance under a variety of power supply conditions, such as voltage variations, power interruptions, and supply changeovers, the ATOP EHG7508 is fully EN50155-certified for today’s demanding railway applications and with essential sections of EN50121-4, the EHG7508 Managed Gigabit Ethernet Switch is suitable for Trackside applications.
