Feature:1. [Learning Encoding] Independent output contact, direct control of various loads; Using learning encoding wireless coding technology (space pairing), no directionality, no interference between switches.2. [Adjustable Working Mode] Suggested Power Supply: DC stabilized power supply above 500mA. Working Mode: Momentary, toggle, latched, delay time, can realize one control multiple or multiple control one.3. [Withstand 5A Current] Each channel of the receiving board can withstand 5A current and can directly drive DC AC loads. Each relay has a set of normally open (normally closed) contact.4. [Tip] For prolonging receiving board life, it is not recommended to control high power load. When controlling 220V, each control is less than 500W, and when controlling 12V, each control is less than 50W.5. [Wide Use] The 12V 1CH wireless relay remote control is suitable for electrical control circuits of anti theft alarm, remote control electric door and window, signal control, industrial control, lifting equipment, etc.Specification:Item Type: Wireless Relay Remote ControlMaterial: ABSWorking Voltage: DC12VStatic Condition: Less Than 7mAWorking Temperature: -40-+80 / -40-+176Receiver Sensitivity: More Than -108dBmWorking Frequency: 433MHzBuilt in Button Battery in the Remote Control: 2 x CR2016(75mAh) (included).Package List:1 x Relay1 x Remote Control
