TRB140005000 / TRB140 LTE Cat 4 Ethernet

The Teltonika TRB140 is an industrial 4G LTE Cat 4 Ethernet gateway created to give Ethernet-based equipment strong cellular internet access. It is an option when you have to link a device, machine, control system, or remote setup to the internet without depending on a fixed broadband connection.

The TRB140 brings together 4G LTE, Gigabit Ethernet, and Teltonika’s RutOS operating system inside a strong aluminum case. It also works with 3G and 2G connections, giving cellular network choices where they are available.

Because of its size, low power use, and industrial design, the TRB140 can be placed in areas where there is not much space. Teltonika mentions uses across automation, energy and utilities, smart cities, transport, enterprise, and retail.

Main Features

• 4G LTE Cat 4 Connectivity

The TRB140 offers 4G LTE Cat 4 connectivity with download speeds of up to 150 Mbps when network conditions support it. It also works with 3G and 2G technologies depending on the network and regional version.

• Gigabit Ethernet Port

The built-in Gigabit Ethernet port allows you to link an Ethernet-based device to the cellular gateway. This makes the TRB140 useful for machines, controllers, monitoring systems and other devices that need an internet connection but do not have their own cellular modem.

• Compact Industrial Design

The TRB140 is 74.5 × 25 × 64.4 mm in size and weighs about 134 g. Its small aluminum case makes it good for installations where there is not much space.

• Industrial-Grade Operation

The gateway is built to work in temperatures from -40°C to +75°C, making it good for industrial setups when installed as per Teltonika’s requirements.

• RutOS Operating System

The TRB140 uses RutOS, Teltonika’s Linux-based system. It gives the gateway the ability to handle networking, setup, security, and management through a web interface.

• Remote Management

The TRB140 works with Teltonika Networks Remote Management System (RMS). This lets devices be monitored and managed from away which can be very helpful when equipment is in hard-to-reach places.

• Industrial Protocol Support

The gateway supports industrial communication protocols like Modbus and DNP3, allowing it to be used in monitoring and automation setups.

• Digital Input and Output

The TRB140 has one input and one digital output. These can be used in monitoring solutions where outside equipment needs to talk to the gateway.

• Micro-USB Interface

A Micro-USB interface is available as a network interface, giving another way to connect for supported uses.

What Is a 4G LTE Gateway?

A 4G LTE gateway links equipment to a network using a SIM card and then provides network access to connected devices.

For example, imagine you have a machine in a place with an Ethernet port but no broadband. You can put a SIM card in the TRB140 and connect the machine to the gateway via Ethernet.

The TRB140 then uses the network to give internet access to that equipment.

This is useful for monitoring, industrial machines, IoT projects, automation systems, and machines that need internet without old-style broadband.

Where Can You Use the Teltonika TRB140?

The TRB140 can be used in work and industrial areas such as:

• Industrial Automation

Link industrial machines, controllers, and monitoring devices to a mobile network for access from far away and data transmission.

• Utilities

Good for checking equipment, utility setups, and places where a wired internet connection is not possible.

• Smart City Projects

The small cellular gateway can give internet access to equipment used in city systems.

• Transportation

It can provide internet for machines and tracking systems in transport settings.

• Enterprise Networks

The TRB140 can offer internet for some Ethernet-based devices in companies and commercial places.

• Retail

Helpful for equipment and systems that need internet access without depending on a wired connection.

Remote Machines & Equipment

A big use case is connecting machines or monitoring gear from the main office or network.

Teltonikas official TRB140 documentation specifically lists industrial and automation energy and utilities, city, transport, enterprise and retail as its main uses.

Example: Remote Industrial Machine

Imagine a machine is placed at a building site or a faraway place.

The machine might have an Ethernet port but no wired internet.

The TRB140 can be attached to the machine using Ethernet. A SIM card provides the connection, and the gateway takes care of the connection between the machine and the mobile network.

Teltonika has recorded an example where the TRB140 was used with construction cranes, connecting monitoring equipment through Ethernet and sending data to a cloud server using Modbus TCP.

Technical Knowledge

Why Use a Cellular Gateway Instead of a Normal Router?

A normal Wi-Fi router is made to give network access to computers, phones, and other local devices.

The TRB140 is more for IoT setup. It is especially useful when the equipment needs a mobile connection and is in a remote or industrial place.

Its small size, case, LTE connection, Ethernet port, digital I/O support for industrial protocols, and remote management features make it right for special setups.

LTE Cat 4 – What Does It Mean?

LTE Cat 4 is a 4G LTE device class that allows download speeds of up to 150 Mbps when the network is good.

The real speed depends on things like the operator, signal strength, network traffic, antenna setup, and local network situations.

SIM Card Connectivity

The TRB140 uses a SIM card to connect to a mobile network. Once that is done, Ethernet devices can use the connection from the gateway.

Teltonika suggests using industrial-grade SIM cards for setups that face temperature extremes, shaking, bad or wet conditions, or places that are hard to get to.

Size & Weight

• Device size: 74.5 × 25 × 64.4 mm
• Device weight: 134 g
• Case: Aluminum
• Operating temperature: -40°C to +75°C

Its small size makes the TRB140 good for tight control cabinets, machines, monitoring systems, and other setups where bigger routers won’t fit.

Connectivity & Interfaces

• 1 × Gigabit Ethernet RJ45
• 1 × SIM slot
• 1 × Digital Input
• 1 × Digital Output
• 1 × Micro-USB interface
• Mobile internet via 4G LTE / 3G / 2G
• SMA antenna connection
• Remote management via Teltonika RMS

Package Information

For the TRB140005000 version, Teltonika says this order code is a normal package with a UK power supply. The specific items included can vary by order code so users should check the package they get before setting it up.

Why Do You Need the Teltonika TRB140?

The Teltonika TRB140 is a choice when you have to give an Ethernet device access to a 4G mobile network without setting up a regular fixed internet connection.

Its main strength is having 4G LTE Cat 4 Gigabit Ethernet, small size, aluminum case, support for industrial protocols, and remote management all in one small device.

For companies handling machines, industrial machines, monitoring systems, or IoT setups, the TRB140 gives a simple way to bring mobile internet to equipment that would otherwise rely on a wired network.

If your project needs size, strong mobile internet access, Ethernet networking, and industrial features, the TRB140 offers all of those in one small industrial gateway.
