Description

The Teltonika TRB145 is a purpose-built industrial LTE gateway engineered to bridge RS485-based field equipment to cloud platforms and control centers via secure cellular links. Its compact, aluminum housing contains a robust ARM Cortex-A7 processor running RutOS, a hardened OpenWrt-based Linux distribution that provides a full-featured networking stack, granular firewall rules, and support for multiple VPN protocols to ensure encrypted data transmission.

Designed for mission-critical IoT and industrial automation, the gateway supports a wide spectrum of industrial protocols, enabling direct integration with Modbus RTU/TCP devices, BACnet/IP building systems, OPC UA servers, and MQTT brokers. This eliminates the need for additional protocol converters, simplifying system architecture. The device features a low operational power footprint and accepts a wide-range DC input, making it suitable for deployment in remote, unpowered, or mobile assets where reliability is paramount.

Key Features

  • Secure Industrial Connectivity: Provides a hardened cellular bridge with advanced VPN (OpenVPN, IPsec, WireGuard) and firewall for secure remote access to critical infrastructure.
  • Protocol-Agnostic Data Gateway: Native support for Modbus, BACnet, OPC UA, MQTT, and DNP3 enables seamless integration with diverse industrial automation and SCADA systems.
  • Ruggedized Design for Harsh Environments: Compact aluminum alloy housing with DIN rail mounting and an extended operating temperature range ensures reliability in outdoor and industrial settings.
  • Centralized Remote Management: Fully manageable via Teltonika Remote Management System (RMS) for over-the-air configuration, monitoring, and firmware updates.
  • Flexible Power and Installation: Wide 9–30 VDC input accommodates various power sources, and the compact form factor allows for easy deployment in control cabinets and enclosures.

Applications

  • Remote monitoring and control of PLCs, RTUs, and industrial sensors over cellular networks (IIoT).
  • SCADA system modernization and legacy serial device (RS485) connectivity to cloud platforms.
  • Smart city infrastructure for utility metering (water, gas, electricity) and environmental sensing networks.
  • Fleet and asset tracking solutions requiring reliable data backhaul from mobile or remote equipment.
  • Building automation systems (BAS) for connecting BACnet/IP devices to centralized management servers.

Frequently Asked Questions

How do I configure the TRB145 gateway for Modbus RTU communication over RS485?

Connect your Modbus RTU device to the gateway's RS485 terminal block (A+, B-). Log into the TRB145 web interface, navigate to the Services > Modbus section, and configure the serial port parameters (baud rate, parity, stop bits) to match your slave device. Enable the Modbus TCP gateway feature to map your RTU registers, allowing external clients to access them via TCP/IP on your designated network port.

What VPN protocols are supported on the TRB145, and how do I set up a site-to-site tunnel?

The TRB145 running RutOS supports OpenVPN, IPsec, WireGuard, and GRE tunnels. For a site-to-site IPsec VPN, access the VPN > IPsec menu in the web UI. Create a new phase 1 proposal defining the encryption and authentication algorithms, and enter your remote gateway's public IP. Then, create a phase 2 proposal specifying the local and remote subnets to be tunneled. Apply the configuration to establish the secure tunnel.

What is the power requirement and typical current consumption of the TRB145 gateway?

The gateway requires a 9–30 V DC power supply via its 4-pin industrial connector. Under typical operational load with LTE connectivity active, the device consumes less than 5 Watts. At 12V input, this translates to an average current draw of approximately 400 mA. The wide input voltage range makes it compatible with standard 12V/24V industrial power systems and battery-backed sources.
