Features:

• 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.
  
• Working voltage DC 12V,with reverse polarity protection.
• 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 , Non-locking (Momentary ),self-locking (Toggle),inter-locking(Latch), 5/20/60/120/250-second delay.
• The 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.
  

Specifications:

Model: AD22A08

Instructions:

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 .

Caution:

1. DTMF audio controller must use stable work of DC 12V power supply (recommendations 2A 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 must output a sound (not muted), or they will not control relays.
