1、Applicable: 12V single channel learning code remote control switch, suitable for theft alarm, remote control electric doors and windows, signal control, industrial control, lifting equipment and other electrical control circuit. 2、Good Performance: The wireless remote control switch module relay contact independent output, very suitable for direct control of all kinds of load; Products using learning code wireless coding technology (space to code), no direction, switch interference. 3、Recommended Power Supply: DC regulated power supply of more than 500mA. Working mode: self lock, interlock, click user free adjustment, can realize one control more, more control one. 4、Convenient: The receiving plate can withstand 10A current in each circuit, and can directly drive DC and AC loads. Each RF relay switch has a set of normally open (normally closed) contacts. 5、Please Note: To prolong the service life of the receiving board, it is not recommended to control the high power load. For 220V, the load control is less than 500W, and for 12V, the load control is less than 50W. Item Type: Relay Switch Material: ABS+PCB Model: AK - RKO1SY Working Voltage: DC12V Maximum Load: ≤10A Standby Power Consumption: <15mA Signal Sensitivity: -105dBm Wireless Frequency: 433Hz Mediation Method: ASK Remote Control Distance: According to The Power of The Remote Control Remote Control Built In Button Battery: 2 x CR2016(75mAh) 1 x Relay Switch 1 x Plastic Box 1 x Remote Control
