TNS5800D-8P4GT-P24 – 12-port Layer 3 EN50155 Industrial M12 PoE Switch, IP67

TNS5800D-8P4GT-P24 is a rugged Layer 3 industrial Ethernet switch designed for harsh mobile and railway environments. Fully compliant with EN50155 and EN50121 railway standards, the device uses robust M12 connectors to ensure secure communication under vibration and shock conditions typical for trains, onboard systems and transport applications.

This model provides 8 × 100M M12 PoE ports (4-pin D-coded) and 4 × Gigabit M12 ports (8-pin X-coded), supporting both data and power transmission for devices such as IP cameras, controllers, passenger information systems and onboard monitoring. Each PoE port delivers up to 30 W in accordance with IEEE 802.3af/at, significantly reducing cabling complexity.

The switch integrates advanced routing and network management capabilities including Static Routing, RIP, VRRP, NAT, together with multiple redundancy technologies: Ring, ERPS (G.8032), STP/RSTP/MSTP. These ensure high network availability in mission-critical architectures. Additional features include QoS, 802.1Q VLANs, IGMP Snooping, PIM-SM/PIM-DM, port trunking, port mirroring and extensive diagnostic tools such as Ping, Traceroute and Loopback.

The TNS5800D-8P4GT-P24 operates from a 24VDC (18–36VDC) power supply and features a fully sealed IP67 metal housing with fanless heat dissipation. The switch is engineered for extreme temperature ranges from -40°C to +75°C, making it suitable for the most demanding industrial and transportation systems. Installation is performed via wall mounting.
