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 operation, 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 Working Voltage: DC 12V Size: Approx. 94 x 62 x 18mm/3.7 x 2.44 x 0.7in Maximum Load: 10A/250VAC, 10A/125VAC, 10A/30VDC, 10A/28VDC, 10A/12VDC

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. Glossary: NO:

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 "Delay": Dial 1, relay 1 "Open", relay 1 "Close"

after a time Mode selection: Eight modes of operation, electric iron
