Robust Industrial IoT & M2M Connectivity Solution
The Teltonika TRB255 is a versatile and robust industrial cellular gateway engineered for mission-critical M2M and IoT applications. It provides a vital communication backbone for both modern and legacy industrial equipment, seamlessly integrating them into one unified solution. Equipped with 4G/LTE (Cat M1), NB-IoT, and 2G EGPRS backward compatibility, the TRB255 ensures reliable and future-proof connectivity. Its dual SIM functionality with auto-failover provides indispensable redundancy, guaranteeing continuous operation by automatically switching between operators in cases of weak signal, data limit, or network failure.
Designed for Industrial Environments
Built to withstand harsh conditions, the TRB255 features a durable aluminum housing and a wide operating temperature range of -40 °C to 75 °C. Its compact design allows for easy integration into space-constrained environments. This gateway is packed with a rich set of interfaces, including an Ethernet port, configurable digital/analog I/Os, and versatile RS232 and RS485 serial ports, making it a universal choice for diverse applications. The integrated GNSS (GPS, GLONASS, etc.) provides accurate location tracking and geofencing capabilities.
Advanced Networking and Security
The TRB255 runs on RutOS, a powerful and secure operating system that offers advanced networking features. It supports a wide range of protocols such as Modbus, MQTT, and SNMP for seamless integration with industrial systems. Security is paramount, with features including a pre-configured firewall, multiple VPN services (OpenVPN, IPsec), and attack prevention mechanisms to protect your critical data and infrastructure. The gateway is also fully compatible with the Teltonika Remote Management System (RMS), allowing for convenient remote monitoring, configuration, and management of your entire fleet of devices.
