Industrial 4G LTE gateway with extended connectivity for demanding IoT applications.
TRB246 is a robust industrial gateway designed for reliable M2M communication in harsh operating environments. The device offers 4G LTE Cat 4 connectivity with speeds up to 150 Mbps DL / 50 Mbps UL, backward compatibility with 3G and 2G networks, and dual SIM support with automatic switching for maximum connection uptime.
The gateway is equipped with a complete set of industrial interfaces including 3× configurable I/Os, RS-232 / RS-485 serial ports, and 10/100 Mbps Ethernet connectivity. It supports key industrial protocols such as DNP3, DLMS/COSEM, and Modbus, enabling seamless integration into existing systems. The aluminum housing with dimensions 83 × 25 × 74.2 mm withstands temperatures from -40 to +75 °C.
Advanced Networking Features
The gateway supports a wide range of networking protocols including static and dynamic routing (BGP, OSPF v2, RIP v1/v2, EIGRP), a firewall with advanced rules, QoS/SQM for traffic prioritization, and hotspot functionality with captive portal support.
Industrial Protocols and Integration
Native support for BACnet router mode, OPC UA client/server, MQTT gateway for Modbus, and full Data to Server functionality with HTTP(S), MQTT, and Azure MQTT for data collection from multiple sources.
Remote Management and Monitoring
Integrated support for the Teltonika RMS platform enables centralized management, FOTA updates, monitoring, and configuration of multiple devices simultaneously. It also supports TR-069, SNMP v1/v2/v3, and JSON-RPC API.
