Teltonika TRB256 - Industrial NB-IoT Gateway, Black

The Teltonika TRB256000000 industrial NB-IoT gateway connects remote machine-to-machine and IoT applications. It uses 4G cellular connectivity and a wired network interface to bridge field equipment. A single Fast Ethernet RJ45 port handles local traffic at 10/100 Mbit/s. The device lacks built-in Wi-Fi and Power over Ethernet, relying instead on a hardwired LAN and a mobile link. Power is supplied via a DC input jack (9–30 V), with a maximum power consumption of 2 W.

The aluminium enclosure provides an IP30 protection rating for technical environments. The included mounting kit supports installation on a desktop, a wall, or a standard DIN-rail. Management is handled through the RutOS operating system, which offers local web-based configuration and remote cloud administration. The software includes a firewall, network address translation, and virtual LAN support for segmented routing. Administrators can filter traffic by IP or MAC address and establish a demilitarised zone. Three front-facing LED indicators display 2G, 4G, and cellular signal strength for onsite diagnostics.
