Specifications: Model: AD22A08Working Voltage: DC 12VSize: 946218mm/3.72.440.7inWeight: 114 gramsMaximum Load: 10A/250VAC, 10A/125VAC, 10A/30VDC, 10A/28VDC, 10A/12VDCPackage Includes:1 x Relay Module, 1 x 3.5mm Audio Cable Read more Glossary:NO: Normal openCOM: Common terminalNC: Normal ConnectRelay open: COM connected NO but disconnected NCRelay 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 delaySelf-locking: Dial 1, relay 1 "Open", dial 1 again, relay 1 "off", and so onInter-lock: Dial 1, relay 1 "Open", other relays "Off"; dial 2, relay 2 "Open", other relays "off", and so on"Delay": Dial 1, relay 1 "Open", relay 1 "Close" after a time Wiring Diagram: Control 12V circuit, the wiring as shown below. Load "LOAD" can be LED lights, fans, motors, routers, and other 12V equipmentsDC 1-110V or AC 85-265V circuit, the wiring is shown below. Load "LOAD" can be LED lights, fans, motors, and other kinds of voltage AC and DC equipments. Read more 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 1/2/3/4/5/6/7/8 by phone_2 keypad to control 8 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 1/2/3/4/5/6/7/8. DTMF audio controller must use stable work of DC 12V power supply (recommendations 2A or above the power adapter).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.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. Read more By default, The AD22A08 8 channel DTMF controller commands are saved in 8 numbers, ‘1,2,3,4,5,6,7,8.’ but you can also modify appropriately the coding instructions with arbitrary 1-4 four bits (0,1,2,3,4,5,6,7,8,9).The controller has two models, "operating mode" and "setting model". The default is "operating mode", but it will be changed into an "setting model" when you press its "key" button.Factory settings: If you forget the instructions you set before, you can reset it: Keeping pressing consistently the key button about 10 seconds until you see that the LED lights on again. After that, the product of operations will restore to its default commands, ‘1,2,3,4,5,6,7,8.’. The setup processes:First, the DTMF controller should work properly, guaranteeing its power supply and audio cable are connected correctly. Second, as pressing the key-button, the LED lights off, the product will go into the "setting model".Thirdly, begin to input commands with mobile phone or computer. Fourthly, when finished the third step, activating the product of key- button or powering it up again. Features:Working voltage DC 12V, with reverse polarity protectionOperating Current: Standby 11-13 MA, 1 relay "open" 44MA, 2 relays "Open" 77MA, 3 relays "Open" 110MA, 4 relays"open" 140MA, 5 relays open 170MA,6 relays open 197MA,7 relays open 223MA,8 relays open 247MA.Eight modes of operation:Non-locking (Momentary ), self-locking (Toggle),inter-locking (Latch), 5/20/60/120/250-second delayThe default control command is 1/2/3/4/5/6/7/8.Example: Dial 1 to control relay 1, dial 2 to control relay 2, dial 3 to control relay 3, dial 4 to control relay 4; control commands can be changed any 1-4 bits. (For more details, refer to " AD22A08_8 channel DTMF controller commands setting manual ").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.
