The RKS-G4028-4GT-2LV-T is a high-performance, modular managed Ethernet switch tailored for industrial automation, power utility, and transportation networks. Equipped with 24 Gigabit copper ports and 4 Gigabit uplinks, it delivers high-speed backbone connectivity with the reliability needed for mission-critical systems. Dual 24/48 VDC isolated redundant inputs provide resilient power, minimising downtime during power fluctuations or failures.
Certified to IEC 61850-3 and IEEE 1613, the switch meets the stringent electromagnetic immunity requirements of power substation environments. It also complies with EN 50121-4 for railway applications, making it suitable for control centres, trackside signalling, and energy infrastructure.
The switch features Turbo Ring and Turbo Chain technology with recovery times under 20 ms, ensuring reliable communications even in large, complex networks. Additional redundancy protocols such as STP, RSTP, and MSTP provide standards-based compatibility. Security is paramount, with support for IEC 62443-4-2, secure boot, ACLs, IEEE 802.1X, SSH, and HTTPS. Centralised access management via RADIUS and TACACS+ helps simplify administration in large deployments.
Its modular architecture supports RM-G4000 series expansion modules, enabling flexible configurations with copper, fibre, or mixed media options. The hardware also supports IEEE 1588v2 PTP for precise time synchronisation, VLAN segmentation, QoS for traffic prioritisation, and bandwidth management to guarantee performance in demanding applications.
With a rugged rackmount design, IP30 protection, and a wide -40 to 75°C operating range, the RKS-G4028-4GT-2LV-T ensures dependable operation in harsh industrial settings. From substations to smart transport systems, it is engineered to provide secure, scalable, and resilient networking for critical operations.
