Description

The Teltonika TRM250 is a dedicated industrial cellular modem engineered for energy-efficient, machine-to-machine (M2M) communication. It leverages LTE Cat-M1 and NB-IoT networks to provide deep coverage and extended battery life for remote sensors and monitoring endpoints, with robust 2G fallback ensuring connectivity in areas with limited LTE infrastructure.

Housed in a rugged, compact aluminum case, the modem is built for reliability in demanding conditions. Its micro USB interface simplifies installation by consolidating power and data transfer, compatible with a wide range of host systems. The inclusion of an external SMA antenna port allows for optimal signal strength, critical for deployments in enclosures or remote field sites.

Key Features

  • Dual-mode LTE for IoT: Supports both Cat-M1 and NB-IoT (NB1) standards for flexible, low-power wide-area network (LPWAN) deployment.
  • Legacy Network Fallback: Integrated 2G (EGPRS) support ensures connectivity in areas without LTE-M or NB-IoT coverage.
  • Industrial Ruggedness: IP30-rated aluminum housing and a wide operating temperature range (-40°C to +75°C) suit harsh environments.
  • Universal Host Compatibility: Plug-and-play USB CDC/ACM driver support for Windows, Linux, and Android operating systems.
  • Optimized for Remote Monitoring: Low power consumption profile ideal for solar-powered or battery-operated telemetry systems.
  • Flexible Mounting: Designed for DIN rail, wall, or flat surface installation to fit standard industrial enclosures.

Applications

  • Smart Metering & AMI: Remote collection of utility consumption data (water, gas, electricity).
  • Industrial Telemetry & IIoT: Monitoring of PLCs, sensors, and equipment status in manufacturing.
  • Asset Tracking & Fleet Management: GPS-less location tracking via cell tower triangulation.
  • Environmental Monitoring: Deploying remote weather stations, soil sensors, or air quality monitors.
  • Smart City Infrastructure: Connecting parking sensors, waste management systems, and street lighting.

Frequently Asked Questions

What operating systems are compatible with the TRM250 modem?

The TRM250 uses standard USB CDC/ACM virtual COM port drivers, making it compatible with Windows (7/8/10/11), Linux (kernel 2.6+), and Android (4.0+) operating systems. It functions as a plug-and-play modem, appearing as a serial device for sending AT commands or establishing a PPP connection for data transfer, requiring no proprietary software for basic operation.

How do I power and connect the TRM250 for a typical deployment?

Power the modem by connecting the included micro USB cable to a stable 5V DC source capable of delivering up to 3.6W. Insert a Mini SIM (2FF) card with an active data plan from a carrier supporting LTE Cat-M1, NB-IoT, or 2G. Connect the provided SMA antenna for optimal signal. Finally, plug the USB cable into your host device (e.g., industrial PC, Raspberry Pi, or gateway) to establish communication via the virtual COM port.

Can the TRM250 operate in extreme temperature environments?

Yes, the TRM250 is designed for industrial use with an operating temperature range of -40°C to +75°C. Its aluminum housing provides thermal dissipation and mechanical protection, while the IP30 rating guards against solid object ingress. This makes it suitable for outdoor enclosures, unheated industrial facilities, or remote telemetry sites subject to wide temperature swings.
