GD-04K Versatile GSM communicator and controller

The GD-04K versatile GSM communicator and controller allows you to remotely control various appliances and report statuses at the same time. It can be controlled remotely by means of a mobile phone with an SMS message or by ringing.

Versatile GSM communicator and controller

GD-04K Versatile GSM communicator and controller

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

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

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

Backed-up operation in the case of a power supply failure (for up to 24 hours) is ensured through the connection of the GD-04A backup module (sold separately).
