The TN-5508A-8PoE Series is a set of EN 50155-compliant managed Ethernet switches designed for powering and connecting onboard railway and wayside equipment. Each unit offers 8 Fast Ethernet M12 ports with IEEE 802.3af/at PoE, delivering up to 30 W per port and a total of 120 W.
Built for railway resilience, the switches feature dual, isolated 24–110 VDC inputs, IP54-rated metal housings, and operate over a temperature range of -40 to 75°C. Certifications include EN 50155, EN 50121-4, IEC 60571, IEC 61373 vibration/shock, and EN 45545-2 fire safety.
Resiliency is supported by Turbo Ring/Chain (<20 ms recovery), as well as RSTP/MSTP for standards-based redundancy. Security features include IEEE 802.1X, TACACS+, RADIUS, HTTPS, SSH, and SNMPv3. Traffic management encompasses VLANs, QoS, IGMP snooping, and support for industrial protocols (EtherNet/IP, Modbus TCP, PROFINET).
The TN-5508A-8PoE Series is ideal for powering IP cameras, Wi-Fi access points, and VoIP phones in rolling stock and critical rail networks.
