The RKS-G4028-PoE-4GS-LV-T is a rugged modular Gigabit managed Ethernet switch that combines high-capacity networking with advanced Power-over-Ethernet (PoE) functionality for industrial automation, transportation, and utility applications. Featuring 24 Gigabit copper ports with IEEE 802.3af/at/bt PoE up to 90 W per port and 4 Gigabit SFP uplinks, this switch delivers both connectivity and power for devices such as surveillance cameras, access points, and IP phones.
Equipped with a 24/48 VDC power input, this model is optimised for low-voltage industrial environments and is built to IEC 61850-3 and IEEE 1613 standards, ensuring robust performance in high EMI conditions typically found in substations and heavy industry. The durable IP30 rack-mount chassis is tested for reliable performance across a wide temperature range of -40 to 75°C, making it suitable for harsh environments.
Moxa’s Turbo Ring and Turbo Chain redundancy technologies provide network recovery in under 20 ms for up to 250 devices, while STP, RSTP, and MSTP support seamless interoperability with standard protocols. Cybersecurity features include secure boot, HTTPS/SSH encryption, ACLs, MAC authentication bypass, port lock, and support for RADIUS/TACACS+ for centralised management, aligned with IEC 62443-4-2 standards.
Advanced PoE management includes scheduling, diagnostics, PD auto-check, and prioritisation, ensuring reliable power for mission-critical endpoints. Network optimisation is achieved through VLANs, QoS, IGMP snooping, and IEEE 1588v2 PTP for precise time synchronisation.
Modular flexibility with RM-G4000 expansion modules makes the RKS-G4028-PoE-4GS-LV-T a future-proof solution for high-density, PoE-enabled industrial networks.
