The Teltonika RUTM55 is an industrial router built for sites that need both high-speed cellular backhaul and connections to older serial equipment. It pairs two 5G modems from Telit with dual SIM and eSIM slots, giving it automatic failover between carriers or SIM profiles. An RS232 port and an RS485 port let it bridge legacy serial devices onto the network, while running Teltonika's RutOS firmware for firewall and VPN control.

Product Features:

• Two Telit 5G modems provide redundant, high-bandwidth cellular connectivity.
• Dual SIM slots plus an eSIM allow automatic failover between carriers or data plans.
• An RS232 port and an RS485 port connect legacy serial equipment to the network.
• A 3-pin industrial power input suits fixed installations in cabinets and vehicles.
• RutOS firmware includes a built-in firewall and support for OpenVPN, IPsec and WireGuard VPN tunnels.
• Teltonika RMS remote management, with a free trial included, lets administrators monitor and configure the router from anywhere.

Application Areas:

• Primary or backup internet connectivity for remote sites, kiosks and vehicles.
• Industrial IoT and M2M deployments where fixed-line internet is unavailable or impractical.
• Integrating legacy RS232/RS485 serial equipment, such as PLCs or monitoring systems, into a modern network.

Selection & Installation Notes:

• Pair the RUTM55 with a suitable 5G-compatible antenna and coaxial cable for the best signal in fixed installations.
• Check SIM and eSIM plan compatibility with local carriers before deployment, since dual SIM failover depends on having active services on both.
• Confirm which serial devices need RS232 versus RS485 before wiring, as the two interfaces use different connectors and signalling.
