Model: Teltonika TRB255

INDUSTRIAL M2M GATEWAY

Features

• 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).
