Introduction

The ToughNet TN-4900 Series, designed for rolling stock Ethernet networks, is a set of high-performance M12 routers with 8 Gigabit ports and up to four bypass relay ports. These routers feature firewall, ETBN, and routing functionality to facilitate the deployment of applications across networks. The TN-4900 Series routers use M12 and other circular connectors to ensure tight, robust connections that guarantee reliability against environmental disturbances, such as vibration and shock.

The TN-4900 Series supports a wide power input range of 24 to 110 VDC and can operate in temperatures of -40 to 70°C for extended periods of time. Furthermore, these routers are compliant with the mandatory requirements of EN 50155, making them suitable for a variety of industrial applications.

Additional Features and Benefits

IEC 61375-2-3, 61375-2-5–compliant ETBN
IEC 62443-4-2:2019–compliant cybersecurity
Routing functionality to divide a large network into hierarchical subnets and allow data and information to communicate across networks
NAT makes IP management easier as end devices in different carriages can use the same IP addresses
Leading EN 50155 Ethernet router for rolling stock applications

Turbo Ring and RSTP/STP for network redundancy
Wall mounting installation
Line-swap fast recovery
Automatic recovery of connected device’s IP addresses
LLDP for automatic topology discovery in network management software
Configurable by web browser, Telnet/serial console, and CLI Windows utility
