EHG2308 is designed specifically for industrial applications in hazardous environments, offering 8 RJ-45 Gigabit ports as well as compliance with CE, FCC, UL, IP50 and RoHS standards. Reliable: Its two redundant power inputs can be connected simultaneously to wide-range DC power sources. If one of the power inputs fail, the other live source takes over automatically, preventing interruptions to critical operations. Efficient: Although it is unmanaged, EHG2308 embeds an advanced Packet Prioritization feature. By reading the QoS field inside the VLAN tag of the packet, it prioritizes those packets that must reach the end device first. In Profinet-based Industrial Automation applications, for example, this feature helps ensure minimal delay on key commands, even during network congestion.
