Remote control based on Quad Band GSM professional.

The C622 is an GSM modem for the supervision and control of remote inputs and outputs.
The C622 allows the remote control, via a mobile phone, two electric supplies (relay outputs 10A 250Vac) via validated SMS messages preceded by a 4 digits password. The relays can be switched for a chosen time (from 1 to 9 seconds) or permanently or up to a reset command. In case of permanent switching, if desired, the status of the relays is stored and reset after a power off and a power on. After a relay has been switched, the GSM remote control replies to the mobile which sent the command with a SMS or making a voice call lasting some ring tone; in the last case the user gets, at no cost (only the ring), the information that the command has been executed. The C622 includes a Phone Directory containing 200 entries; the mobile numbers existing in the Directory can activate the relay 1, in monostable or bistable mode with a plain ring to the device without engaging the line and, then, at no cost (Opengate function).
The C622 has two digital optoisolated inputs controlled by means a continuous voltage ranging between 10V and 30V or with clean contacts. The state of the inputs can be sensed at every time sending a SMS message. One by one, every input can be set up to send a warning when the input value exceeds or falls below the set threshold.
When a warning event happens on the inputs (digital or analogical ones), the GSM remote control sends by its own a warning SMS including a text, customizable for every input, up to five mobile numbers. After the warning SMS has been sent, the C622 even makes a voice call lasting some ring in order to draw the user attention on the arrival of the message.
