Teltonika FMC225: Rugged 4G LTE Cat 1 GPS Tracker with RS485/RS232 and Dual SIM
The Teltonika FMC225 is an advanced, water and dust resistant (IP67) 4G LTE Cat 1 GPS tracker designed for the most demanding IoT and fleet management environments. Equipped with RS485 and RS232 interfaces, Dual SIM functionality and an internal backup battery, this terminal offers unprecedented reliability for real-time monitoring of heavy transport, agricultural vehicles, construction equipment and logistics applications.
Why the Teltonika FMC225?
For fleet operators and IoT integrators, continuous connectivity and reliable data under harsh conditions is crucial. The Teltonika FMC225 stands out for its combination of an extremely robust IP67 enclosure and broad integration capabilities. Thanks to the serial RS485 and RS232 ports, you can effortlessly add complex accessories such as fuel level sensors or RFID readers. In addition, Dual SIM support ensures guaranteed connectivity; if the primary network goes down, the second SIM card takes over seamlessly. This makes the FMC225 the ultimate, future-proof hardware choice for tough industrial and agricultural applications where failure is not an option.
Advanced connectivity and reliability
Thanks to 4G LTE Cat 1 connectivity with automatic fallback to 2G (GSM), you are always assured of a stable connection to your vehicles. The rugged IP67 enclosure ensures the tracker continues to perform optimally even in heavy rain, exposure to chemicals, dust and mud.
Versatile integration with RS485, RS232 and Bluetooth
What makes the FMC225 indispensable for advanced telematics is the ability to connect a wide range of external accessories. Via the integrated RS485 and RS232 ports, you easily link specialized sensors and scanners. In addition, the built-in Bluetooth 4.0 LE (Low Energy) supports wireless communication, ideal for monitoring temperature and humidity with BLE beacons in refrigerated transport, for example.
Intelligent telematics and CAN bus readout
The FMC225 supports CAN data reading of both light vehicles and heavy and specialized transport (in combination with optional Teltonika CAN adapters). Smart event detection helps you optimize your fleet and increase safety with instant notifications in case of aggressive driving behavior (Eco-driving), accidents (crash detection) or unauthorized movements.
