Description

The Moxa TN-4900 ETBN EN 50155 industrial router is built for rolling-stock networks, combining IEC 61375 ETBN functionality with static, RIP and OSPF routing. This ETBN variant has no firewall and no PoE, and provides four 10/100 M12 D-coded ports, four Gigabit M12 X-coded ports and four further Gigabit M12 X-coded ports with bypass relay (4GTX + 4GTXBP).

It accepts redundant 24 to 110 VDC power inputs, runs across -40 to 70°C and uses a conformal-coated IP40 metal housing for wall mounting. M12 connectors, IEC 62443-4-2 certified security features, IPsec VPN and TRDP protocol support make it suited to train backbone and on-board network deployments.

Features

- IEC 61375-2-3 / 61375-2-5 compliant ETBN functionality
- Bypass relay on four Gigabit ports maintains connectivity if the device loses power
- IEC 62443-4-2:2019 certified cybersecurity features
- Static, RIP v1/v2 and OSPF routing with NAT and VRRP
- IPsec VPN, secure boot, RADIUS and TRDP railway protocol support
- Turbo Ring v2 and RSTP/STP network redundancy
- M12 connectors for vibration and shock resistance
- Isolated redundant 24 to 110 VDC power inputs
- Management via web interface, Telnet/serial console, CLI and Windows utility

FAQs

Q: Does this TN-4908 model include a firewall?
A: No. This is the ETBN variant, which provides IEC 61375 ETBN functionality and routing without a firewall.

Q: Does this router support PoE?
A: No. This model has no PoE ports. It is a non-PoE variant.

Q: What does the bypass relay do?
A: Four of the Gigabit M12 X-coded ports (4GTXBP) include a bypass relay, so the link can remain connected through the device if it loses power.

Q: What power supply voltage does it accept?
A: It accepts redundant dual inputs rated 24/36/48/72/96/110 VDC, with an operating range of 16.8 to 137.5 VDC, via an M12 K-coded 5-pin connector.

Q: Is it suitable for railway installations?
A: Yes. It is compliant with EN 50155, EN 50121-4 and EN 45545-2, tested to IEC 61373 shock and vibration, and rated for -40 to 70°C.

Q: What connectors are used on the Ethernet ports?
A: The 10/100 ports use M12 D-coded 4-pin connectors and the Gigabit ports use M12 X-coded 8-pin connectors.
