Know Quark-elec GSM/WiFi Remote Control in one minute
QK-G025 module is an industrial grade product intended to provide remote control of DC motors or any DC powered devices. It allows operators to control remote equipment and machinery by free calls through the GSM network. Up to four mobile phone numbers (SIM card numbers) can be registered with it. These mobile phones can belong to families/ technicians or engineers who have a requirement to control corresponding devices. Just dial from the registered SIM cards then the barriers or doors will be opened/closed, or the machine will be turned on/off. There are no call costs since this GSM control module will not answer the call and it will immediately take action after identifying the registered SIM card numbers.
— Four control mobile phones. One main control terminal and up to 3 additional control terminals can be registered with QK-G025.
— Two digital alarm inputs. Various sensors can be monitored, e.g., photocell receiver, obstacle detector, position sensitive detector, motion sensor, temperature/wind detector, carbon dioxide detector, water leak detector.
— The DC motor output can be set as Dead Man mode (action during dialing period) or Pulsed Time mode (action time is set as a fixed time).
— The DC motor output can be fixed polarity or alternating (polarity changed alternatively).
— Prevent SIM being turned off by provider by sending status SMS at set intervals (between 28 to 99 days).
