Teltonika TRB246 — Industrial 4G LTE Cat 4 IoT Gateway for M2M Connectivity

The Teltonika TRB246 is an industrial 4G LTE IoT gateway with RS232 and RS485 serial interfaces, designed for M2M connectivity and integration of serial-interface industrial equipment into mobile IoT networks. It is deployed in industrial automation, building automation, and fleet management where 4G LTE connectivity must be combined with stable serial communications and low power consumption under extreme temperature conditions.

The combination of Ethernet, RS232, and RS485 ports enables direct connection of a wide range of industrial equipment — sensors, meters, controllers, and serial-interface devices — without additional external modules. Support for a broad range of network protocols ensures compatibility with diverse IoT platforms and automation equipment, simplifying integration into existing infrastructures without complex architectural modifications.

The integrated security package — VPN, firewall, and unauthorised access protection — guarantees data integrity and confidentiality in industrial networks with multiple access points. FOTA support eliminates the need for physical interventions for firmware updates, reducing operational costs in distributed or hard-to-reach installations. Low power consumption and resistance to extreme temperatures ensure continuous operation in demanding industrial environments.

Recommended for industrial automation and IoT where integrating RS232 and RS485 equipment over 4G LTE is the central project requirement, building automation and BMS systems with serial-interface sensors and equipment, fleet management and remote monitoring at locations without fixed network access, and any IoT deployment where a compact gateway with multiple serial interfaces, advanced security, and energy efficiency represents the optimal mobile connectivity solution.
