Teltonika TRB255 gateway
The Teltonika TRB255 Network Gateway is a gateway for industrial cellular applications that supports LPWAN connectivity options. The model features flexibility of use with an RJ45 Fast Ethernet interface, serial interfaces (RS232, RS485) and multiple input/outputs. The device supports low-traffic cellular communications for NB-IoT telemetry devices, LTE Cat M1 technology, and is backward compatible with EGPRS (2G) wireless data technology.
Uninterrupted connection and management from the cloud
The Teltonika TRB255 network gateway offers a cost-effective and scalable way to upgrade large amounts of legacy infrastructure or implement new M2M interoperability projects using support for various cellular standards. In addition, built-in GNSS, dual SIM cards and compatibility with Teltonika's remote control system enable not only reliable infrastructure connectivity, but also easy monitoring and management.
Excellent protection against external influences
The device is designed to operate in extreme conditions (on the street, in vehicles), for which its housing is made of aluminum resistant to corrosion and physical loads. Reliability of the gate is also ensured by handling the supply voltage in a wide range(from 9 to 30 V).
