Teltonika TRB140 – Industrial 4G LTE Gateway for IoT and M2M Connectivity

The TRB140 is an ultra-compact industrial LTE Cat 4 gateway designed for reliable single-device mobile connectivity in industrial IoT applications and remote automation systems. It is deployed in projects requiring LTE Cat 4 throughput, Gigabit Ethernet, and digital I/O in a minimal form factor with low power consumption and no dependency on fixed-line infrastructure.

The LTE Cat 4 modem delivers higher data transfer speeds compared to Cat 1, supporting applications with greater bandwidth requirements for industrial data transmission. The Gigabit Ethernet port enables direct low-latency connection to the target device, while the integrated digital I/O provides local control and monitoring capability without additional modules. The micro USB port completes the local access and configuration options.

The gateway includes a comprehensive security and remote management feature set: firewall, OpenVPN, IPsec, and SMS control. Native integration with the Teltonika RMS platform enables centralised monitoring and configuration of distributed devices, and FOTA support eliminates on-site visits for firmware updates — critical for installations in hard-to-reach locations.

Recommended for single industrial device LTE Cat 4 internet connectivity, telemetry and remote monitoring systems with moderate to high bandwidth requirements, IoT deployments at locations without fixed network access, and projects where compact size and energy efficiency are primary selection criteria. The ultra-compact form factor simplifies integration into existing equipment or technical enclosures with limited space.
