Industrial 4G LTE Modem Teltonika TRM282, Global Version
The Teltonika TRM282 is a rugged and compact industrial cellular modem designed for reliable data transmission in IoT and M2M applications worldwide. The built-in Telit module with LTE Cat 4 support guarantees stable global connectivity, while the combination of a modern USB-C and RS-232 serial interface enables easy integration with both new systems and legacy industrial machinery without the need for complex network architecture redesign.
Global Connectivity and Legacy Device Integration
The TRM282 modem ensures a seamless transition to LTE Cat 4 mobile networks with download speeds of up to 150 Mbps and backward compatibility with 3G and 2G networks. A key benefit is the integrated RS-232 interface (DB-9 connector), which makes the modem an ideal solution for remote data collection from legacy devices, industrial controllers, PLCs, or sensors. The second communication interface, USB-C, simultaneously serves as a virtual network interface and provides flexible power supply.
Practical Applications
The Teltonika TRM282 industrial modem is primarily used in IoT, industrial automation, smart cities, energy, and transportation, where it serves as a rugged communication bridge for remote data collection.
Extended Functionality with Built-in GNSS
In addition to standard data communication, the Teltonika TRM282 also features a built-in GNSS satellite receiver. Higher reliability of mobile and satellite signal reception in demanding environments is ensured by the external antenna connectors (2× SMA for LTE, 1× SMA for GNSS).
Rugged Hardware for Extreme Conditions
The TRM282 is housed in a robust aluminum enclosure with IP30 protection. It is designed for continuous operation in demanding industrial environments and reliably works in a temperature range from −40 °C to 65 °C. For flexible installation in cabinets, a wide power supply range can be used via the 4-pin industrial connector (9–30 VDC) or standard 5V power directly through the USB-C port.
