Maximum Reliability: Your Dual-SIM Gateway for Critical M2M Applications
In the world of Machine-to-Machine (M2M) and the Industrial Internet of Things (IIoT), a connection loss is not an option. This is exactly where the Teltonika TRB245 comes in. With its intelligent dual-SIM functionality, it ensures an almost indestructible connection. If your primary provider's Network fails, the gateway switches lightning-fast and fully automatically to the second SIM card. Whether it's a weak signal, data limit, or roaming – the TRB245 keeps your systems and machines reliably online as a Dual SIM Router for Machine Control.
Bridge to Industry 4.0: Connecting Legacy Systems with RS232/RS485
Are your systems still running with proven, but older serial interfaces? No problem! The TRB245 is the perfect bridge between traditional industrial technology and modern IP networks. Via the integrated RS232 and RS485 ports, you can connect PLC controls, sensors, meters, and terminals directly. This makes your existing infrastructure fit for remote maintenance, data acquisition, and the requirements of Industry 4.0, without having to replace expensive hardware.
Robustness for Extreme Conditions: Built for Industrial Use
The TRB245 is no ordinary router. Its compact, yet extremely robust aluminum housing with IP30 protection, the wide input voltage range of 9 to 30 VDC, and the impressive operating temperature range of -40 °C to 75 °C prove: This gateway is designed for continuous operation in control cabinets, vehicles, and demanding industrial environments. Reverse polarity and overvoltage protection ensure additional operational safety.
Full Remote Control: Management with RutOS and Teltonika RMS
The heart of the TRB245 is the flexible RutOS, an OpenWrt-based operating system that offers you countless configuration options. Set up secure VPN tunnels with OpenVPN, IPsec, or WireGuard, control actions via SMS, or use the I/Os for alarms. In combination with the Teltonika Remote Management System (RMS), managing even hundreds of devices becomes child's play. Access the web interface remotely, install firmware updates, and monitor the status of your entire fleet from a central dashboard. This device is a prime example of professional Teltonika 4G / 5G Routers.

Frequently Asked Questions (FAQ)
Can I use the Teltonika TRB245 as a normal WiFi Router for home?
No, the TRB245 is a specialized industrial gateway without WiFi functionality. It is designed for connecting machines and systems via mobile communication, not for home networks.
What does "Dual SIM with Failover" mean?
The gateway can accommodate two SIM cards from different providers. If the connection of the primary SIM card fails (e.g., due to poor reception), the device automatically switches to the second SIM card to maintain the internet connection.
What are the RS232/RS485 interfaces needed for?
These serial interfaces are commonly used in industry for communication with older or specialized devices such as PLC controllers, sensors, meters, or terminals that do not have a modern Ethernet connection.
Is the gateway suitable for use in vehicles?
Yes, due to the wide input voltage range of 9-30 VDC, it can be directly connected to the vehicle's electrical system (12V or 24V). The GNSS functionality also enables location tracking.
What is the Teltonika Remote Management System (RMS)?
RMS is a cloud platform that allows a large number of Teltonika devices to be centrally monitored, configured, and managed. You can remotely access the web interface, perform firmware updates, and receive status alarms.
