MOXA RKS-G4028-PL-L3-12XGS-T Introduction
The Moxa RKS-G4028-PL-L3-12XGS-T Rackmount Ethernet Switch is a modular Layer 3 managed switch designed for high-bandwidth Industrial Networking. It provides 12 fixed 1000/2500/10000BaseSFP ports and two expansion slots supporting up to 16 additional Gigabit Ethernet ports. The switch supports IEEE 802.3bt PoE with up to 90 W per port and a total PoE budget of 720 W when dual power modules are installed. Dual isolated power options and an out-of-band management port support flexible Network Infrastructure design for demanding Industrial Communication systems.
Applications of Moxa RKS-G4028-PL-L3-12XGS-T
Moxa RKS-G4028-PL-L3-12XGS-T is suitable for power substation automation, railway networks, intelligent transportation, and factory automation. Its 10GbE SFP+ interfaces provide high-speed backbone connectivity between control systems, servers, and industrial network segments. Layer 3 functionality supports routing between network segments, while VLAN, QoS, LACP, STP, RSTP, MSTP, and 802.1X provide structured Industrial Ethernet management. PoE interfaces can supply compatible field devices, making the switch suitable for SCADA, IIoT, and distributed Industrial Automation deployments.
Benefits of Using Moxa RKS-G4028-PL-L3-12XGS-T
Moxa RKS-G4028-PL-L3-12XGS-T combines 10GbE backbone connectivity, Layer 3 networking, modular expansion, and PoE in a rackmount platform. Its two expansion slots let engineers add copper, SFP, or PoE interfaces to meet system requirements. The switch operates from -40 to 75°C and supports IEC 62443-4-2 Security Level 2 requirements. IEC 61850-3, IEEE 1613, EN 50121-4, and NEMA TS2 certifications support deployment in power, railway, and traffic environments. Dual power modules, overload and reverse-polarity protection, and a 5-year warranty further support reliable Industrial Connectivity and network uptime.
