Description
The industrial 4G LTE router Teltonika RUT906 is designed to connect industrial equipment, automation systems and remote monitoring devices through cellular and wired networks. It combines 4G LTE Cat 4 connectivity with dual SIM functionality, Wi-Fi, Ethernet, RS232 and RS485 serial interfaces, GNSS positioning and configurable input/output connections.
Unlike basic cellular routers, the RUT906 provides multiple industrial communication interfaces for connecting equipment that uses serial communication or requires digital and analog signal monitoring. This makes it a suitable connectivity solution for industrial IoT deployments, remote equipment management, energy applications and automation systems.
4G LTE Cat 4 Connectivity with Dual SIM
The RUT906 supports 4G LTE Cat 4 connectivity, with backward compatibility for 3G and 2G networks. The manufacturer specifies maximum cellular speeds of up to 150 Mbps download and 50 Mbps upload on LTE Cat 4. Actual performance depends on the mobile operator, network coverage, signal conditions and selected hardware version.
The router includes two physical SIM slots and supports automatic SIM switching. It can switch between SIM cards based on configurable conditions such as weak signal, data limits, roaming, network unavailability or connection failure. This helps maintain cellular connectivity when the primary SIM connection becomes unavailable.
For installations that need alternative internet connectivity, the RUT906 also supports wired WAN and network backup configurations. This flexibility is useful for remote locations where maintaining a connection to monitoring systems or connected equipment is important.
RS232 and RS485 Serial Communication
A major advantage of the RUT906 is its support for both RS232 and RS485 serial communication. These interfaces allow the router to connect to industrial equipment that uses serial data exchange rather than standard Ethernet networking.
The RS232 interface is provided through a DB9 connector, while the RS485 interface uses a 6-pin industrial socket. Supported serial functions include serial-over-IP and modem-related applications.
These interfaces make the router relevant to deployments involving:
Industrial controllers and automation equipment
Serial-enabled meters and monitoring instruments
PLCs and compatible field devices
Industrial communication systems
Equipment that exchanges data through RS232 or RS485
By connecting serial equipment to a cellular network, the RUT906 can support remote data communication and monitoring without requiring every connected device to have its own internet connection.
GNSS Positioning and Location Services
The RUT906 includes GNSS functionality for location-related applications. The manufacturer lists support for GPS, GLONASS, BeiDou, Galileo and QZSS in its product documentation, with supported capabilities depending on firmware and configuration.
Location information can be used in remote asset monitoring, mobile equipment tracking and applications where the geographical position of connected equipment is relevant.
The router also supports NTRIP functionality, which can be used in suitable GNSS-related applications. This provides additional flexibility for deployments that need location data alongside cellular communication.
Configurable Digital and Analog I/O
The RUT906 includes input and output interfaces for connecting external equipment and monitoring signals. Its I/O capabilities make it useful in applications where a router needs to interact with physical devices, sensors or control systems.
The manufacturer specifies digital and analog input options, digital open-collector outputs and a relay output. The device also provides an additional digital input and digital output through its power connector.
Depending on the application and configuration, these interfaces can support status monitoring, event-based actions and control-related functions. For example, an installation may use an input to monitor an external equipment signal or an output to trigger a compatible connected device.
Check the official pinout and electrical ratings before connecting field equipment.
Ethernet and Wi-Fi Connectivity
The RUT906 provides four 10/100 Mbps Ethernet ports, comprising one WAN port and three LAN ports. The WAN port can also be configured as LAN, depending on the network setup.
It also supports 2.4 GHz Wi-Fi based on the 802.11b/g/n standard, also known as Wi-Fi 4. Wireless operation includes Access Point and Station modes, allowing the router to provide local wireless access or connect to an existing wireless network.
The combination of Ethernet, Wi-Fi and cellular connectivity makes the RUT906 suitable for installations that need to connect different types of network-enabled devices through a single industrial router.
RutOS for Network Management and Security
The RUT906 runs RutOS, Teltonika’s OpenWrt-based Linux operating system. It provides networking, monitoring, security and remote-management functions through its web interface and supported management tools.
Its networking features include routing, firewall configuration, VLAN, network backup, load balancing and connection monitoring. VPN options listed in the manufacturer’s datasheet include OpenVPN, IPsec, GRE, PPTP, L2TP, SSTP and ZeroTier.
For industrial communication and IoT applications, the router supports protocols and functions such as MQTT, Modbus, BACnet, OPC UA and data-to-server integrations. The available functions depend on the installed firmware, packages and configuration.
USB and microSD Storage Expansion
The RUT906 includes a USB 2.0 host port for connecting supported external devices, such as storage drives and USB-to-serial adapters. Its documented USB applications include Samba sharing and USB-to-serial functionality.
It also provides an internal microSD slot, supporting storage expansion up to 64 GB according to the datasheet. This can be useful in deployments that require local storage or additional data-handling capabilities.
Industrial Applications of the RUT906
The combination of cellular connectivity, serial interfaces, GNSS and configurable I/O makes the RUT906 suitable for several industrial and IoT applications.
Industrial automation: Connect compatible PLCs, controllers and serial-enabled equipment to remote monitoring or control networks.
Energy and utilities: Support communication with compatible meters, monitoring instruments and utility equipment using serial or network interfaces.
