GSM-GPRS Remote monitoring controller TCG120

TCG120 is a GSM-GPRS Remote monitoring controller for distributed IO monitoring and control.


TCG120 is an IO controller for GSM-GPRS remote monitoring and control over mobile networks. It has two digital inputs, two analog inputs. Its 1-Wire interface supports up to four Teracom humidity and temperature sensors. It’s two relays have normally open and normally closed contacts.

The relays can be activated either remotely (via SMS or HTTP API command) or locally – from the status of the monitored parameter. Only one parameter can manage the relay at the same time, but for every parameter can be sent e-mail or SMS for alert conditions.

TCG120 can initiate a connection (HTTP Post) to the remote dedicated servers. The payload of this post is XML file, with current values of monitored parameters.

HTTP post can be sent periodically or on previous set alarm conditions. This is very useful in client-server systems for GSM-GPRS remote monitoring and control

The controller can be used as a standalone device or as a part of data acquisition (SCADA) systems.
