Teltonika TRB245 – Industrial 4G LTE Gateway for IoT and M2M Connectivity

Teltonika TRB245 is an industrial LTE Cat 4 gateway designed to integrate both modern and legacy industrial equipment into IoT and M2M networks through RS232 and RS485 serial interfaces. It is deployed in industrial automation, SCADA systems, smart metering and remote monitoring where reliable mobile connectivity, serial communication and time synchronisation are simultaneously required for continuous operation.

The gateway features an LTE Cat 4 modem with Dual SIM support and automatic failover, enabling transparent carrier switching when the primary connection is lost without interrupting active communications. RS232 and RS485 interfaces allow direct connection of legacy industrial equipment — PLCs, meters and sensors — without external converters, simplifying overall installation architecture. The integrated time synchronisation service ensures timestamp consistency across distributed systems where temporal accuracy is critical for logging and coordination.

TRB245 includes I/O ports for field signal monitoring and control, an industrial power connector with secure mechanical retention and redundant WAN for maintaining connectivity in scenarios with unstable primary connections. Software features — SMS control, firewall, OpenVPN, IPsec and Teltonika RMS compatibility — ensure secure data access and centralised remote management for device fleets across distributed infrastructures.

Recommended for industrial system integrators, utility operators and companies in energy, transportation and precision agriculture requiring a compact IoT gateway with redundant LTE connectivity, serial interfaces and secure data management. TRB245 consolidates all essential functionality for connecting legacy industrial equipment to modern IoT infrastructures into a single compact device.
