RKS-G4028 Series

28G-port (with 802.3bt PoE option) full Gigabit modular managed Ethernet switches


28G-port (with 802.3bt PoE option) full Gigabit modular managed Ethernet switches


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.

The modular design of the RKS-G4028 Series also makes network planning easy, and allows greater flexibility by letting you install up to 28 Gigabit ports with various connector types.

Features and Benefits

  •  Meets a wide range of demands from Fast Ethernet to full Gigabit industrial networks (up to 28 Gigabit ports)
