GD-02K-DIN Universal GSM Communicator and controller

Using the GD-02K-DIN


2 outputs – power and signal – activates / deactivates the output with an option to set an impulse (1 s – 24 h).

  • Via SMS or by dialling from 100 phone numbers


  • using an input it follows the status of anotherdevice (mains dropout, fault, etc.).

Temperature measuring

  • with the possibility of a temperature sensor JB-TS-PT1000 measures the current score and reports when the limit value is exceeded


  • using the JB-TS-PT1000 temperature sensor the GD-02K-DIN module measures the current temperature and according to the pre-set temperature (required or antifreeze) switches the REL1 power relay output (e.g. electrical boiler, heater). The required and antifreeze temperature can be set remotely by an SMS command and you can also switch between them.

Impulse counter

  • allows you to connect up to two external consumption meters with an impulse output (e.g. electricity meters, gas meters, water meters) or one consumption meter with the distinction between low and high tariffs. The impulse counter mode provides information via SMS about their current status or about exceeding the pre-set limits.
