    This is the DTMF audio controller with four channels, any phone or fixed telephone with DTMF key code remotely controls product relay "open" and "close".(the majority of smartphones and functions machine are DTMF code). Our software "DTMF Dial" (installed in a computer) can be also provided to control relays.4.jpg

    As shown above, by phone remote control relay. You need two phones, one as a receiver (phone_1), the other one as a transmitter (phone_2); mobile phone_1 connected by DTMF audio cable 3.5MM audio controller (the controller to be powered), and then using phone_2 ( may be a fixed telephone) call the phone_1, phone_1 answered, so that two phone call each other; then dial 1/2/3/4 by phone_2 keypad to control four relays .


    As shown above, you can install one of our "DTMF Dial" software in your computer, through the software control DTMF audio controller. At first, use 3.5MM audio cable to the computer video port and audio port controller, then click on the software to control relays 1/2/3/4.



    1 DTMF audio controller must use stable work of DC 12V power supply (recommendations 1A or above the power adapter)
    2 remote control the controller by a mobile phone, the receiver must be the phone with 3.5MM audio interface, the transmitter can be a cell phone or landline
    3 as a receiver of the phone or a computer installed the "DTMF Dial" software must output a sound (not muted), or they will not control relays.
    NO: Normal open
    COM: Common terminal
    NC: Normal Connect
    Relay open: COM connected NO but disconnected NC
    Relay close: COM disconnected NO but NC connected COM.
    Non-locking (Momentary ): Dial 1 (2/3/4 is the same), relay 1 "Open", relay close after 1 second delay
    Self-locking: Dial 1, relay 1 "Open", dial 1 again, relay 1 "off", and so on
    Inter-lock: Dial 1, relay 1 "Open", other relays "Off"; dial 2, relay 2 "Open", other relays "off", and so on
