GSM-GPRS Remote monitoring controller TCG120

GSM-GPRS Remote Monitoring Module Supplier TGG 120

TCG120 serves as an IO controller designed for remote monitoring and control over GSM-GPRS mobile networks. It offers two digital inputs, two analog inputs, and supports up to four Teracom humidity and temperature sensors through its 1-Wire interface. The device also features two relays with both normally open and normally closed contacts.

These relays can be activated either remotely, using SMS or HTTP API commands, or locally based on the status of the monitored parameter. Each relay can manage only one parameter at a time, but for each parameter, email or SMS alerts can be configured to trigger under specific conditions.

TCG120 is capable of initiating a connection (HTTP post) to remote dedicated servers. The payload of this HTTP post contains an XML file with the current values of the monitored parameters. These HTTP posts can be sent periodically or based on previously set alarm conditions. This feature is particularly valuable in client-server systems designed for remote monitoring and control over GSM-GPRS networks.

The controller is versatile, suitable for use as a standalone device, or it can seamlessly integrate into data acquisition (SCADA) systems.

Key Specifications:

  • Quad-bands GSM connectivity for extensive coverage.
  • Convenient setup options through USB (using a Windows setup program) or SMS.
  • 2 digital inputs supporting both 'dry contact' and 'logic level' modes.
  • 2 analog inputs with a voltage range of 0 to 60VDC.
  • 2 relay outputs featuring both Normally Open (NO) and Normally Closed (NC) contacts.
  • 1-Wire support, enabling connectivity for up to 4 Teracom temperature and humidity-temperature sensors.
  • SMS-based alarm alerts for a maximum of 5 phone numbers.
  • Email-based alarm notifications for up to 5 email recipients, with SMTP support and TLS encryption.
  • Single call control feature, allowing relay control with a single call from as many as 100 authorized numbers.
  • Push mode for transmitting XML data via HTTP post to a remote server.
  • Support for HTTP API commands for flexible control.
  • Firmware updates can be conveniently executed either over USB or through GPRS.

Use Cases:

  • Monitoring and controlling environmental conditions within vehicles.
  • Regulating temperature and humidity levels.
  • Remote management of street lighting.
  • Automation of industrial processes.
  • Deployment in home and office security systems.
  • Monitoring storage conditions for pharmaceuticals and food products.
