The TN-5516A-8PoE is an EN 50155-certified managed Ethernet switch designed for railway and rolling stock networks requiring both data and power delivery. It provides 16 M12 ports: 8 IEEE 802.3af/at PoE ports delivering up to 30 W per port (120 W total), and 8 Fast Ethernet ports for standard connectivity.
PoE support enables the switch to power onboard devices such as IP surveillance cameras, wireless access points, and VoIP phones directly, reducing cabling complexity and simplifying installation. Dual isolated 24–110 VDC inputs ensure redundant, stable power delivery.
Built with vibration-resistant M12 connectors and housed in an IP54-rated enclosure, the TN-5516A-8PoE is designed to withstand shock, vibration, EMI, dust, and humidity. Certified to EN 50155, EN 50121-4, IEC 60571, IEC 61373, and EN 45545-2 fire protection, it is engineered to meet stringent railway requirements. Broad operating capability of -40 to 75 °C ensures long-term reliability in harsh conditions, with optional conformal coating.
Redundancy is achieved through Turbo Ring and Turbo Chain (<20 ms recovery), along with standards-based RSTP and MSTP. Security features include IEEE 802.1X, TACACS+, RADIUS, ACLs, HTTPS, SSH, and SNMPv3. Traffic management is supported with VLANs, QoS, IGMP snooping, and LACP aggregation.
With integrated PoE power, strong redundancy, and industrial certifications, the TN-5516A-8PoE is a reliable choice for powering and managing mission-critical railway systems, including CCTV, passenger information, and onboard Wi-Fi.
