Universal remote GSM communicator and controller JABLOTRON GD-04K is designed to control appliances (eg. thermostats) by SMS or by ringing. The module is equipped with 2 power outputs with a status or pulse reaction. For status monitoring the GD-04K module has four input terminals which react to grounding (connecting to the GND terminal). Activation / deactivation of an input terminal can be reported as an SMS, dialling in or a combination of both these options to up to 100 authorised telephone numbers.

The parameters can be set in several ways:

• By SMS
• USB cable (or remotely) in combination with SW GD-Link 2.0.0 (or higher)

Up to 100 authorized telephone numbers can be stored in the GSM communicator.

In the event of a power failure, the GD-04K can be supplemented with a back-up module, that provides up to 24 hours backup.
