Main Features

• 4G LTE Cat 4 Connectivity

The Teltonika TRB140 delivers 4G LTE Cat 4 service. Also works on 3G and 2G networks. The Teltonika TRB140 is ideal for giving equipment a cellular link when fixed broadband is not possible or convenient.

• Gigabit Ethernet

It has an RJ45 port that supports 10/100/1000 Mbps. The Teltonika TRB140 lets you plug in controllers, monitoring gear, machines, and other network devices.

• Compact Industrial Design

It is tiny, measuring 74.5 × 25 × 64.4 mm. It weighs only 134 g. The Teltonika TRB140’s aluminium case is made for industrial jobs where space is tight.

• DIN Rail Installation

It can be mounted on a DIN rail on a surface or directly on a PCB. It gives installers choices for fitting it into control cabinets and industrial gear.

• RutOS Operating System

It runs RutOS, a Linux system based on OpenWrt. It offers a platform for network setup and complex networking tasks.

• Remote Management with RMS

It works with Teltonika Networks Remote Management System (RMS). RMS lets you manage and watch the device from afar, which is handy when the gateway sits in a hard‑to‑reach spot.

• Industrial Protocol Support

It supports DNP3 and Modbus protocols. The Teltonika TRB140 is ready for industrial monitoring and automation jobs.

• Low Power Consumption

It uses less than 5 W of power. The Teltonika TRB140 is perfect for setups where low power use is crucial.

• Wide Operating Temperature

It works from –40 °C to +75 °C. It can survive environments if installed as Teltonika says.

Teltonika’s official guide lists industrial & automation, energy & utilities, smart city, transportation, enterprise, and retail as places to use the Teltonika TRB140.

Technical Knowledge – How Does TRB140 Work?

The Teltonika TRB140 works in a simple way.

Insert a SIM card that fits the Teltonika TRB140. The Teltonika TRB140 then links to the network with 4G LTE, 3G, or 2G.

After that, plug your Ethernet device into the Teltonika TRB140’s Gigabit port.

The Teltonika TRB140 lets gear that usually needs a wired line talk over the link.

For example:

machine → Ethernet → TRB140 → 4G LTE network → Internet / remote system

The Teltonika TRB140 is especially handy for machines far away where putting in a fixed broadband line is hard.

What Is LTE Cat 4?

LTE Cat 4 is a class of 4G LTE technology. When the network conditions are good, LTE Cat 4 can deliver download speeds of up to 150 megabits per second.

The real speeds you see depend on the network, the strength of the signal, how busy the network is, the antenna configuration, and local surroundings.

The TRB140 is built as a cellular gateway for industrial and IoT uses, not as a normal home Wi‑Fi router. Teltonika calls the TRB140 a rugged LTE gateway.

• Connectivity

The TRB140 provides:

• 4G/LTE Cat 4
• 3G
• 2G
• 1 × Gigabit Ethernet
• 1 × Mini SIM
• 1 × Micro‑USB
• 1 × Digital input
• 1 × Digital output
• 1 × SMA LTE antenna connector

The official Teltonika datasheet says the Ethernet port can run at 10, 100 or 1,000 megabits per second and the SIM slot is a Mini SIM of type 2FF.

• Power & Installation

The TRB140 accepts 9–30 VDC through its 4‑pin power socket. Teltonika also specifies reverse‑polarity and surge protection on the DC input. Passive PoE over pairs is supported, but Teltonika notes that it is not compatible with IEEE 802.3af or 802.3at standards.

The compact aluminium unit can be installed using:

• – DIN rail mounting
• – Flat‑surface mounting
• – PCB mounting

Size & Weight

• Dimensions: 74.5 × 25 × 64.4 mm
• Weight: 134 g
• Housing: Aluminium
• Protection: IP30
• Operating temperature: –40 °C to +75 °C

Because the TRB140 is small, it fits well in control cabinets, machinery, automation gear and tight enclosures where space is short.

Example Application

Picture a machine that sits at a site. It has an Ethernet port but no fixed internet link.

Rather than running a separate wired internet line, the TRB140 can plug into the machine via Ethernet and then use a SIM card to reach the cellular network.

This arrangement works for monitoring, equipment talking, and sending machine data to a distant server or management system.

Teltonika also lists uses for the TRB140 for signage and for remote industrial gear.

Why Do You Need the Teltonika TRB140?

The Teltonika TRB140 is handy when you want an Ethernet‑based machine or device to get onto a network.

Rather than using a big router, the TRB140 offers a small, low‑power, rugged unit that focuses on cellular connectivity.

The TRB140’s mix of 4G LTE Cat 4 Gigabit Ethernet, industrial ports, DIN rail mounting, RutOS and RMS compatibility suits businesses that must link equipment in industrial sites.

For automation remote monitoring, IoT projects, power systems, transport gear, and other cases where steady cellular links matter, the TRB140 can provide a useful link between Ethernet gear and the mobile network.
