MOXA RKS-G4028-PL-12XGS-T Introduction
The Moxa RKS-G4028-PL-12XGS-T Rackmount Ethernet Switch is a modular Layer 2 managed switch designed for high-bandwidth Industrial Networking. It provides 12 fixed 1000/2500/10000BaseSFP ports and two expansion slots for up to 16 additional Ethernet ports. The switch supports IEEE 802.3bt PoE with up to 90 W per port and a 720 W total PoE budget when dual power modules are installed. Its modular power architecture and -40 to 75°C operating range support demanding Industrial Ethernet and Network Infrastructure deployments.
Applications of Moxa RKS-G4028-PL-12XGS-T
Moxa RKS-G4028-PL-12XGS-T is suitable for factory automation, transportation, power substations, and other Industrial Communication systems. Its 10GbE SFP+ ports provide high-bandwidth backbone connectivity for control servers, industrial devices, and network aggregation. The switch supports VLAN, QoS, LACP, IGMP, SNMP, and multiple redundancy protocols for structured Industrial Networking. Its PoE interfaces can power compatible field devices, while the out-of-band management port provides an independent path for network administration.
Benefits of Using Moxa RKS-G4028-PL-12XGS-T
Moxa RKS-G4028-PL-12XGS-T combines high-speed connectivity, modular expansion, and PoE power delivery in a rackmount platform. Two expansion slots allow engineers to select suitable copper, SFP, or PoE modules as network requirements change. The switch supports up to 720 W of PoE power with dual power modules and includes overload and reverse-polarity protection. IEC 62443-4-2 Security Level 2 certification supports industrial cybersecurity requirements. The -40 to 75°C operating range and IEC 61850-3, IEEE 1613, EN 50121-4, and NEMA TS2 certifications make it suitable for demanding automation, power, railway, and traffic applications.
