Teltonika TRB141 – Industrial 4G LTE Gateway with GPIO for IoT and Automation

The TRB141 is a compact industrial 4G LTE gateway with GPIO interfaces, built for remote control and monitoring of equipment in industrial IoT applications and automation systems. It is deployed where LTE Cat 1 mobile connectivity must be combined with direct I/O control — digital, relay, analog, and isolated — without reliance on fixed-line infrastructure.

The available I/O interfaces allow direct connection of sensors, actuators, and automation equipment without additional expansion modules. The micro USB port provides convenient local access, while the high-performance computing platform ensures stable processing of control logic under simultaneous multi-stream data conditions.

The gateway runs RutOS — Teltonika's OpenWRT-based operating system — delivering operational reliability and extensive configuration flexibility. The integrated software stack includes VPN, IPsec, firewall, and SMS control for secure remote administration. Native integration with the Teltonika RMS platform enables centralised management of distributed device fleets, and FOTA support eliminates on-site visits for firmware updates, reducing operational costs for remote installations.

Recommended for industrial automation systems with GPIO-based control, remote equipment monitoring over LTE, telemetry deployments with analog and digital sensors, and IoT applications at locations without fixed network access. The compact form factor simplifies integration into distribution panels and technical enclosures where space is limited.
