The GSM Relay Controllers from Precisol Automation are extensions to our Relay Switches range with extra functionality available for monitoring remote digital events. Powered by 5V or 12V supplies, these devices can be installed effortlessly and operated with SMS sent from conventional phones. As these remote access devices communicate using GSM modem, these devices can be deployed in any area that has GSM connectivity which practically includes most of many countries. The remote controlled relays along with protected inputs can be used for home automation, industrial, remote security and alarm systems etc.

Once enabled, the administrator of the device has capabilities to add new users and assign them access rights such as monitor only or monitor and control etc. The added users can be removed at any point of time. Commands from external phones and or unauthorized messages from configured users are ignored. Various parameters of the device such as on and off de-bounce time of the inputs, on time, on and off delays, etc can be configured using SMS. Also each user can configure the rate and kind of update from the device depending on their need.
