Teltonika RUT901 — Industrial 4G (LTE) WiFi Router for IoT and Professional Networking

Teltonika RUT901 is an industrial 4G LTE router built for M2M and IoT applications requiring reliable mobile connectivity in demanding environments. It is deployed in industrial automation, critical infrastructure and remote monitoring scenarios where automatic failover between mobile operators and continuous network availability are core operational requirements.

The router features a 4G LTE Cat 4 modem with Dual SIM support and automatic carrier switching, maintaining connectivity without manual intervention when the primary network becomes unavailable. Wi-Fi 802.11b/g/n accommodates up to 100 simultaneous clients, covering wireless connectivity needs across industrial sites. The integrated digital I/O — one input and one output — enables direct interaction with field equipment without additional hardware.

Running RutOS, based on OpenWrt, RUT901 supports industrial protocols including Modbus TCP, DNP3 and DLMS/COSEM, alongside multi-protocol VPN — OpenVPN, IPsec, WireGuard and ZeroTier — and dynamic routing via BGP and OSPF for secure enterprise network integration. Remote management is handled through the Teltonika RMS platform, TR-069, SNMP v1/v2/v3 or JSON-RPC, providing centralised visibility and control over distributed deployments.

Recommended for M2M system integrators, critical infrastructure operators and organisations in energy and transportation requiring a compact industrial gateway with redundant mobile connectivity and scalable remote management. The aluminium IP30 enclosure, operating temperature range from -40°C to +75°C and 9–30 VDC power input with reverse polarity protection support installation in electrical panels, vehicles and uncontrolled field locations.
