TELECONTROL SYSTEM USING GSM MOBILE NETWORK GSM AD

GSM AD is a telecontrol system using gsm network.
With our mobile phone we can control any device that can be controlled with relays. There are infinite possibilities. It has two outputs (12 Α / 250 V), and two inputs from "cold" contacts.
Checks its power supply and sends SMS when powered up and in case of power failure. When used in three-phase networks, its supply must be connected in the output of the 3-phase controller, if we want to send SMS for any phase failure.
POWER UNIT T200 is needed for operation. It is the power supply and inside are the two output relays. It needs an 11 terminals tube type socket. GSM AD is the gsm tranceiver where the SIM card is connected, as well as the antenna and also carries the input terminals. This needs an 8 terminals (octal) socket.
CAPABILITIES

We can program GSM AD's parameters and functionality with programming SMSs.
We can control one output by unanswered calls or SMS, and GSM AD will answer back for success or failure by calls or SMS. The second output is controlled only with SMS. The two inputs can inform us for events in the installation field.
  We can program the two relays to operate for only 2 sec, for use in start-stop-by-buttons electrical panels.
We can do GSM AD "start" by an unanswered call. It will close the line and will call back one time for "start"  acknowledge. The second unanswered call is a "stop", the GSM AD closes the line and calls back two times as a "stop" acknowledge.
There is  the capability that the calls back to the user be initiated by an input (INPUT 1). This way we know if and when our action is carried out with no errors. In this mode if input does not follow the commands, no calls back are made.
In the mode above, during normal operation, if INPUT 1 opens, an SMS will be send to declare an error.
All messages are programmable.
Users can check available credit with the phone company and renew it if necessary by SMSs to GSM AD using an SMS forward scheme, with no fuss.
