Description
The Teltonika TRB255 Industrial LTE Gateway is engineered for mission-critical IoT applications requiring robust, secure, and long-range wireless connectivity. It leverages LTE Cat M1 and NB-IoT networks for low-power, wide-area data transmission, with 2G fallback for maximum coverage reliability. The gateway’s dual SIM capability with intelligent auto-switching provides essential network redundancy, ensuring continuous operation even if one carrier fails.
Equipped with a comprehensive suite of interfaces, including a 10/100 Mbps Ethernet port, RS232, and RS485 serial lines, the TRB255 acts as a versatile bridge between legacy industrial equipment and modern IP networks. Its support for protocols like Modbus RTU/TCP, DNP3, BACnet, and MQTT facilitates seamless data exchange with PLCs, RTUs, smart meters, and cloud platforms. Advanced security features, including VPN tunnels and a built-in firewall, protect data integrity from edge to cloud.
