Industrial 4G LTE Cat 1 Connectivity
The TRM240 provides 4G LTE Cat 1 connectivity with maximum speeds of up to 10 Mbps download and 5 Mbps upload.
It also supports 3G and 2G cellular technologies, providing additional network compatibility where supported by the mobile network.
LTE Cat 1 is well suited to industrial and IoT applications that require reliable cellular data connectivity without the higher bandwidth and complexity of more powerful LTE router solutions.
Add Cellular Connectivity to Existing Equipment
One of the main advantages of the TRM240 is its simplicity.
Rather than replacing existing equipment with a cellular-enabled version, the TRM240 can provide an external mobile data connection through USB.
This makes it suitable for upgrading compatible:
- Industrial computers
- PCs
- Embedded systems
- Industrial controllers
- Remote monitoring equipment
- Data acquisition systems
- IoT gateways
- Automation equipment
- Digital signage systems
- Kiosks and terminals
The modem acts as the cellular communications interface while the connected host equipment manages the application.
USB Interface
The TRM240 uses a microUSB interface for both data connectivity and power.
Power requirements are:
- 5 VDC via microUSB
-
Maximum power consumption: 3.2 W
This simplifies integration because a separate industrial DC power input is not required when a suitable powered USB connection is available.
External Cellular Antenna
The TRM240 includes a dedicated:
1 × SMA connector for mobile antenna
An external antenna can be positioned to achieve better cellular reception than may be possible with an internal antenna, particularly when equipment is installed inside cabinets, machinery or other locations where cellular signal strength may be reduced.
This also provides flexibility to select an appropriate antenna for the installation.
Rugged Industrial Aluminium Housing
Unlike consumer USB cellular dongles, the TRM240 is designed specifically for industrial applications.
It features a durable anodised aluminium housing and panels, providing a robust enclosure for fixed installations.
Its compact dimensions are approximately:
74.5 × 25 × 64.5 mm
with a weight of only:
131 g
The small form factor allows the modem to be integrated into control cabinets, equipment enclosures and other installations where space is limited.
Wide Operating Temperature
The TRM240 is designed to operate across a wide temperature range of:
-40°C to +75°C
with operating humidity of:
10% to 90% non-condensing
This makes it considerably better suited to industrial and remote applications than conventional consumer cellular modems.
Flexible Mounting
The TRM240 can be installed using several mounting methods:
- DIN rail
- Wall mounting
- Flat-surface mounting
These mounting methods require the applicable additional mounting kit.
DIN rail installation is particularly useful when integrating the modem into industrial control panels, switchboards and automation cabinets.
SIM Card Support
The modem provides:
1 × Mini SIM (2FF) slot
supporting 1.8 V and 3 V SIM cards.
The SIM is installed internally behind the removable front panel, helping keep the SIM securely installed once the modem has been deployed.
Windows, Linux & Android Support
The TRM240 supports integration with several common operating systems and driver environments.
Software and driver support includes:
- Windows Connection Manager
- Windows USB drivers
- Linux USB drivers
- Android RIL driver
- Windows NDIS driver
- Linux Gobinet driver
- Linux driver support
This provides flexibility for integrating the modem with industrial computers, embedded systems and other host devices.
AT Command Control
The TRM240 can also be controlled using 3GPP TS27.007 and enhanced AT commands.
AT command support is useful for developers, system integrators and OEM applications requiring direct software control of the modem and cellular connection.
LED Status Indicators
Three front-panel LEDs provide quick visual indication of modem operation:
These indicators allow technicians to quickly check power and cellular network status during installation and troubleshooting.
Australian & New Zealand Version
Teltonika provides a specific TRM240 hardware version covering Australia and New Zealand.
The Australian/New Zealand version supports:
4G LTE-FDD
4G LTE-TDD
3G
2G
The standard order code listed by Teltonika for this regional version is:
TRM240100000 – Standard package
This is an important consideration for Australian deployments, as the correct regional hardware version should be selected for local cellular frequency compatibility.
