4G LTE wireless I/O module

TCG120-4 is a 4G LTE wireless I/O module with MQTT support.

Description

TCG120-4 is a 4G LTE wireless I/O module. In addition to the 4G, the device also supports 3G and GSM-GPRS, which makes it a good choice of a last-mile module that can communicate from a point with any mobile network coverage. The choice of communication technology is automatic by default but can be fixed during the setup.

The input/output peripherals of the device include 2 digital inputs, 2 analog inputs, and two relays with normally open and normally closed contacts. In addition, the module supports a 1-Wire interface to which up to 4 Teracom sensors can be connected.

The initial setup of the device is made through the graphical interface using a standard browser. On the field, the device can be set up remotely either with SMS or HTTP API commands.

The device can operate in offline mode. In this mode, the relays can be activated by the alarm state of any of the monitored parameters – digital/analog inputs or sensors. In this way, the device can directly control some processes.

4G LTE wireless I/O module may be part of supervisory control and data acquisition (SCADA) systems. For this purpose, the supported protocols for M2M communication are used – HTTP API and MQTT.

In the case of HTTP API is used, the module periodically sends its whole status via XML or JSON file. While if MQTT is used, only a specific parameter can be sent.
MQTT is optimized to work on networks with even the scarcest of bandwidth. More about MQTT can be read in our blog too.
