DTMF 8CH Relay Phone Voice Decoder Remote Controller Switch Module for Home Automation

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/12VDCInstructions: You need two phones, one as areceiver (phone_1), the other one as a transmitter (phone_2); mobile phone_1connected by DTMF audio cable 3.5MM audio controller (the controller to bepowered), and then using phone_2 ( may be a fixed telephone) call the phone_1, phone_1answered, so that two phone call each other; then dial 1/2/3/4/5/6/7/8 by phone_2keypad to control 8 relays . Caution: 1.DTMF audio controller must use stable work of DC 12V power supply(recommendations 2A or the power adapter)2. Remote control the controller by a mobile phone, the receiver must be with 3.5MM audio interface, the transmitter can be a cell phone orlandline3. As a receiver of the phone must output a sound (not muted), or they will not control relays.
