TCG140: GSM-GPRS remote IO module for site monitoring and control over a mobile network.

TCG140 is a GSM-GPRS remote IO module for distributed monitoring and control over mobile networks. The module can be used as a standalone device or as part of SCADA (Supervisory Control and Data Acquisition) systems.

The GSM-GPRS remote IO module has two digital inputs, two analog inputs with a 0-10 V range, and two analog inputs with a 0-10 V or 0-20 mA range. The customer sets the mode of the analog inputs via the Web interface.

The device supports 1-Wire and RS-485 (MODBUS RTU) interfaces. Both interfaces can carry up to 8 sensors, shared between the two interfaces in a random ratio.

The device records all monitored parameters in its internal FLASH memory. Records are made within the previously set time interval and/or under an alarm condition. The log file can be periodically uploaded to a dedicated server via HTTP Post.

The device has four relays with normally open or normally closed contacts. The relays can be activated remotely (SMS, call, or HTTP API command) or locally. For local activation, one of the monitored parameters is assigned to the relay – the alarm status of the parameter activates the relay.

TCG140 can initiate a connection (HTTP Post) to remote dedicated servers. The payload of this post is an XML file, with the current values of the monitored parameters. The HTTP Post can be sent periodically or under alarm conditions. In response to the HTTP post, an HTTP API command can be returned for relay activation or modification of some settings.

In addition to the HTTP Post alert, the device can send SMS and/or emails as supplementary alerts to up to 5 SMS and email recipients.
