TCG140-4 is a 4G LTE universal IO module. It covers LTE Cat.1 communication with up to 5 Mbit upload. The device supports also 3G and 2G wireless communication and provides data connectivity on LTE-FDD, DC-HSDPA, HSPA+, HSDPA, HSUPA, WCDMA, EDGE, and GPRS networks. This makes it usable practically anywhere in the world where is available some kind of cellular coverage.

4G LTE universal IO module can work autonomously but it is specially optimized for M2M and IoT applications. The main option for M2M communication is HTTP API. The device supports HTTP and HTTPS Post with XML or JSON file.

The analog inputs with their standard ranges together with the MODBUS RTU interface make the integration of the unit into industrial applications very easy.

TCG140-4 is the successor to the popular TCG140. The two modules differ only in technology and communication ranges. The entire input-output peripherals and digital interfaces are 100% identical. This makes it easy to migrate from the 2G device to the 4G LTE module in places where 2G services are to be shut down.
