Description: Operating voltage: 11-12.5V(input) VCC: Connect the power supply positive GND: Connect the power supply negative Operating current: about 40mA (relay pull state) Static operating current: 4mA or so (relay release state) Receiver size: 50 * 35 * 22 (with housing, housing with screw hole) Module type: 433MHz learning wireless access module Can learn the common 433MHz remote control (such as 2262 2260 2264 EV1527, etc.), stable performance, easy to operate Specification: Material: FR4 glass plate Size: Approx. 55x35x22mm / 2.17x1.38x0.87inch Receiving distance: between 15-1000 meters (through the wall) Working mode: self-loing, jogging, interloing three working modules Scope of application: water pump, light bar, lamp, home appliances, machinery and equipment, mechanical switch, roll gate, shutter curtain, etc. Work instructions: D2 (power indicator), D4 (relay switch indicator), D3 (learning indicator) Output mode: output is passive output, the module is mainly used as a switch; (for the often open), COM (for the common), CB (for the regular closure) (Note: CB and COM normal state is connected, Switch used when the CB is usually not used, only and COM two interfaces) First, learning methods: 1, power, press and hold the module above the learning button, learning light D3 flash 1, release the button, and then press the need to learn the remote control button (such as A key), learning light flash 3 to prove this button to learn success 2, power, press and hold the module above the learning button, learning light D3 flash 2, release the button, and then press the need to learn the remote control button (such as B key), learning light flash 3 to prove that the other button Learning success Second, the wireless function to clear the method: After power, has been holding down the learning button, learning light D3 first flash 2, and then quily flash 3, said the module cleared successfully Third, self-loing, jogging, interloing operation Interlo: power state, press and hold the learning button after power, learning light D3 flash 2, the release button, this time set to interlo output. (This mode is used for two keys of the remote control operation, A button to open, B button off) Self-loing: power state, press the learning button after power, learning light D3 flash 3, the release button, this time set to self-loing lo output. (For single-button control) Jogging: power off state, press and hold the learning button after power, learning light D3 flash 4, the release button, this time set to jog output. (For single-button control) Paage Includes: 1x Wireless Switch Module 1x Remote controller
