The ZJIES6028M-24GT-DC is an IEC61850-3 compliant industrial managed Layer-2 19-inch rack-mount gigabit switch with 24 × 10/100/1000Base-T copper (RJ45) ports — a pure-copper, all-gigabit access switch with no fiber ports. It provides full management — QoS, VLAN, IGMP Snooping/GMRP, Port Trunking, SNMP v1/v2/v3 — and ring-redundancy protocols (STP/RSTP/MSTP/ERPS/ZJRing) with self-healing under 20 ms. AC 220V input, wide-temperature design and strong EMC immunity make it suitable for substation automation and demanding industrial sites. The ZJIES6028M series scales to 28 gigabit ports across many copper/fiber configurations.
