The RKS-G4028-PoE-4GS-HV-T is a high-performance, modular Gigabit managed Ethernet switch designed for mission-critical industrial networks that require advanced Power-over-Ethernet (PoE) support. With 24 Gigabit copper ports delivering IEEE 802.3af/at/bt PoE, each capable of up to 90 W output, plus 4 SFP uplinks, it provides an ideal backbone for powering and connecting demanding devices such as IP surveillance cameras, Wi-Fi 6 access points, and rugged industrial phones.
Designed for substation automation, transportation, and process control, this model features a 110/220 VDC/VAC isolated input and is certified to IEC 61850-3 and IEEE 1613 standards for high electromagnetic immunity and stable operation in power utility environments. Its rugged IP30 rackmount design supports reliable operation across a wide -40 to 75°C range.
Moxa’s Turbo Ring and Turbo Chain technologies deliver sub-20 ms recovery times for up to 250 switches, while STP, RSTP, and MSTP ensure standards-based redundancy. Security features include IEC 62443-4-2 compliance, secure boot, SNMPv3, HTTPS/SSH encryption, access control lists, MAC authentication bypass, port lock, and centralised RADIUS/TACACS+ authentication.
PoE-specific management tools include scheduling, PD auto-checking, diagnostics, and power prioritisation, ensuring reliable power delivery for critical applications. Network optimisation functions include VLAN, QoS, IGMP snooping, bandwidth management, and IEEE 1588v2 PTP time synchronisation.
With modular flexibility via RM-G4000 expansion modules, extended service life, and advanced cybersecurity, the RKS-G4028-PoE-4GS-HV-T is built to simplify network deployment while ensuring high availability and long-term reliability in harsh industrial environments.
