Teltonika TRB145 – Industrial 4G LTE Gateway with RS485 for IoT and SCADA

The TRB145 is an industrial LTE gateway with RS485 serial interface, built for remote device management and M2M connectivity in IoT and industrial automation environments. It is widely deployed in telemetry systems, SCADA infrastructure, and smart metering applications where LTE Cat 1 connectivity must be combined with serial communication over RS485.

The integrated LTE Cat 1 modem and RS485 port enable direct connection of serial devices to mobile networks without additional hardware. The software stack includes firewall, OpenVPN, IPsec, and SMS control capabilities — providing the security and remote access features required for unattended or hard-to-reach installations.

TRB145 integrates natively with the Teltonika RMS (Remote Management System), enabling centralised monitoring and configuration of multiple units from a single dashboard. FOTA (Firmware Over The Air) support eliminates on-site visits for firmware updates, lowering operational costs for distributed deployments.

Recommended for industrial automation systems with RS485 equipment, remote telemetry and metering nodes, off-grid locations without fixed internet access, and any IoT use case where a single serial device must be managed remotely over LTE. The compact, ruggedised design supports installation in demanding physical environments.
