The Bivocom TG451 is an industrial IoT gateway specifically designed for applications such as water pump station, power substation, in-vehicle WIFI and traffic light systems that requires all types of data acquisition and transfer from different sensors and controllers to a remote location via cellular network at a high speed data rate.

The TG451 is equipped with rich I/O including RJ45, RS-232/RS-485, DI/DO, USB, WIFI, and support protocols such as MQTT, Modbus RTU/TCP, Modbus to Json, TCP/UDP to collect and transfer data from diverse sensors and controllers to the cloud, and remote location. The TG451-LQEDS-WG industrial gateway has dual SIM for applications that requires redundancy which ensures reliable cellular network between different carriers and the independent GPS function allows you to track your mobile assets such as trucks, buses and delivery vans. Also, the WAN port allows you to auto switch between WWAN and WAN.

This industrial gateway compact design is easy for embedding into an enclosure for on-site device with wall mount or Din-rail mount mechanism.
