Moxa RKS-G4028-L3-PoE-4GS-HV-T - Layer 3 modular managed Ethernet switch with 4 100/1000BaseSFP ports, 3 slots for Ethernet modu
by MOXA

The RKS-G4028 Series is designed to meet the rigorous demands of mission-critical applications for industry and business, such as power substation automation systems (IEC 61850-3, IEEE 1613), railway applications (EN 50121-4), and factory automation systems. The RKS-G4028 Series Gigabit and Fast Ethernet backbone, redundant ring, and 24 VDC, 48 VDC, or 110-220 VDC-VAC dual isolated redundant power supplies increase the reliability of your communications and save on wiring costs.
