GD-04K Versatile GSM Communicator and Controller

It has 2 power outputs (250V/5A) for control. The outputs can be set as status or pulse (pulse duration from 1s to 10h). When the output is controlled by ringing, a limit on the number of control events can be assigned to each phone number (suitable e.g. for various paid entrances where the phone number should have a certain credit representing the number of entries).

It has 4 inputs that react to ground causing off/on type reports in the form of SMS and ringing. Up to 100 authorized numbers can be set for control and reporting.

GD-04K can also be set locally via USB using GD-Link 2.0 setup software or remotely via the settings website.

Safety operation in the event of a power failure (up to 24 hours) is ensured by connecting the backup module GD-04A (sold separately).
