The Teltonika RUTM51 is an industrial 5G router with dual SIM, five Gigabit Ethernet ports, dual-band Wi-Fi 5, USB and digital I/O. It is Teltonika's entry point to industrial 5G, aimed at sites that want 5G speeds without paying for features they will not use.

The defining capability of the RUTM51 is bringing 5G to cost-sensitive projects. It keeps the essentials of a larger industrial router, with five Gigabit ports, Wi-Fi 5 and digital I/O, and adds dual SIM failover so the connection switches networks automatically on weak signal, data limits or a lost connection. Wired WAN and Wi-Fi WAN can also act as backup paths.
