RKS-G4028 Series

Introduction

Product Features

  • Meets a wide range of demands from Fast Ethernet to full Gigabit industrial networks (up to 28 Gigabit ports)Modular interfaces for flexible connector type combinations
  • Support for IEEE 802.3bt PoE for up to 90 W output per port
  • High EMC immunity compliant with IEC 61850-3 and IEEE 1613
  • Hardware-based IEEE 1588 PTP for high-precision time synchronization
  • Turbo Ring and Turbo Chain (recovery time < 20 ms @ 250 switches) , and STP/RSTP/MSTP for network redundancy
  • -40 to 75°C operating temperature range
  • Supports MXstudio for easy, visualized industrial network management
  • Developed according to the IEC 62443-4-1 and compliant with the IEC 62443-4-2 industrial cybersecurity standards

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.
