Teltonika 4G LTE GPIO Gateway - TRB141

Industrial 4G LTE Gateway to Digital I/O, Relays, and Analog

The Teltonika TRB141 is a compact industrial gateway designed to control and monitor remote equipment via the cellular network. It is particularly suited for IoT and M2M applications requiring inputs/outputs, relays, or an analog input without the need for an additional PLC.

4G Gateway to Industrial I/O

The TRB141 uses LTE Cat 1 connectivity with a physical SIM slot. It allows for transmitting field information, receiving remote commands, or triggering actions via its input/output interfaces.

Control and Monitoring Interfaces

The gateway features 3 digital inputs, 1 analog input, 2 relay outputs, and 2 configurable I/Os. This rich set of interfaces allows for connecting sensors, dry contacts, alarms, relay commands, or simple industrial signals.

VPN, Security, and Administration

The TRB141 supports essential network security features: firewall, SMS control, secure remote access, and administration via RutOS. VPN protocols such as OpenVPN, IPsec, GRE, PPTP, and L2TP facilitate integration into professional architectures.

Industrial Installation

With its 9-30 VDC power supply, an operating range of -40 °C to +75 °C, and DIN rail, wall, or flat surface mounting options, the TRB141 is suitable for technical cabinets and field installations.
