Description
The Teltonika TRB256 Industrial LTE Gateway is engineered for large-scale, mission-critical IoT and M2M deployments where reliability and protocol compatibility are paramount. Its multi-mode cellular radio supports LTE Cat-M1 and NB-IoT for low-power wide-area connectivity, alongside legacy EGPRS fallback, with specialized 450 MHz band support for enhanced building penetration and extended coverage in remote or dense urban areas.
Built around an industrial-grade architecture, the gateway provides dual SIM auto-failover for carrier redundancy, a 10/100 Mbps Ethernet port for local network backbone, and serial interfaces (RS232/RS485) for connecting legacy industrial equipment. Integrated support for Modbus, DNP3, BACnet, and MQTT allows seamless data aggregation and transmission to cloud platforms or on-premise SCADA systems without additional protocol converters.
Housed in a compact, ruggedized aluminum enclosure rated IP30, the TRB256 is designed for continuous operation in extreme temperatures from -40°C to +75°C. Advanced security features including VPN and firewall protection ensure data integrity for smart metering, utility monitoring, and critical infrastructure applications.
