Product Details
overview
The IEC7028 series two-layer gigabit industrial Ethernet switch is a high-performance Ethernet communication product developed specifically for the industrial communication field. This product uses high-performance industrial grade switching chips that comply with the IEC61850-3 power standard. In terms of interface configuration, it supports 4 Gigabit SFP ports and 24 100Mbps optical optional interfaces, providing multiple interfaces such as 100Mbps electrical port, 100Mbps optical port, and Gigabit SFP. Among them, the SFP Gigabit port can be equipped with either Gigabit optical module or Gigabit RJ45 electrical port module. Adopting a 1U rack mounted installation method, it can meet the needs of different application sites. The network management system supports multiple network protocols and industry standards, such as STP/RSTP, 802.1Q VLAN, QoS function, LLDP, IGMP static multicast function, port aggregation, port mirroring, etc; Having comprehensive management functions, supporting port configuration, port statistics, access control, network diagnosis, fast configuration, online upgrades, etc; It can support access methods such as CLI, WEB, Telnet, SNMP, etc. The IEC7028 series supports redundant DC110/220V power supply. Meet the demand for electricity supply. The port supports front-end or back-end output methods. Meet different industrial communication sites.
