Description

TRB255 can be used to integrate modern and legacy industrial equipment into one solution via RS232, RS485 & Ethernet interfaces.

This industrial LTE Cat M1 & NB-IoT gateway is backward compatible to EGPRS (2G) networks. It can still be used with 2G network, however in case it gets shut down, there is a possibility to switch to LPWAN connectivity options.

TRB255 has a wide range of industrial and networking features such as Modbus, SMS control, Firewall, OpenVPN and more.

This product is compatible with the Teltonika Networks Remote Management System (RMS).
