The TN-G4516-8GPoE-4XGPoE-WV-CT-T is an EN 50155-compliant managed M12 Ethernet switch designed specifically for railway applications requiring high-speed data transfer, reliable power delivery, and enhanced environmental protection. With its conformal-coated PCB, this model offers superior resistance against dust, humidity, salt mist, and chemical contaminants, extending service life in demanding operating conditions.
Featuring 4x 10G PoE ports, 8x Gigabit PoE ports, and 4x Gigabit copper interfaces, the switch supports multi-Gigabit throughput to handle data-intensive services such as passenger Wi-Fi, HD CCTV streaming, and train control communications. The integrated IEEE 802.3af/at PoE+ supports up to 30 W per port, with a total 120 W power budget, enabling simple, centralised powering of IP-based devices across the train network.
Dual isolated 24–110 VDC inputs provide reliable, redundant power. The robust metal housing, IP40 protection, and wide temperature range of -40 to 70°C ensure dependable operation in harsh railway environments. Full compliance with EN 50121-4, IEC 61373, and EN 45545-2 guarantees EMC performance, shock/vibration endurance, and fire safety.
Resilient networking is supported by Moxa’s Turbo Ring and Turbo Chain redundancy, ensuring recovery within 50 ms for large-scale deployments, complemented by STP/RSTP/MSTP compatibility. Security features include HTTPS, SSH, TACACS+, RADIUS, IEEE 802.1X, and port-based locking to safeguard critical infrastructure.
With its blend of 10G capacity, PoE versatility, redundancy, and conformal coating protection, the TN-G4516-8GPoE-4XGPoE-WV-CT-T is an ideal solution for mission-critical rail transport networking.
