Description: I.receiving board parameters Working voltage: DC12V; Quiescent Current: 10mA Remote control distance: 20-200 meters or more (different distance matching with different remote control) Receiving frequency: 433MHz; Receiving sensitivity: -105dB Contact type: relay normally open normally closed electrical independent contact Contact capacity: 3A; Size: Approx. 72mm 48mm 22mm II. Remote control parameters: Working voltage: 12V/1Pcs 27A battery (battery included) Quiescent Current: more than 1uA; Working Current 20mA Remote control distance: 50m (spacious); Coding Mode: learning mode (EV1527 Frequency modulation ASK; Mounting Method: Paste on any places or install on the standard 86 bottom box III. Basic introduction: This is a 433M four-channel wireless remote control switch receiving board with DC12V working voltage. The three output modes of self-locking, jogging and can be selected through the jumper on the receiving board; four relays each provide a pair of normally open and normally closed independent contact;controller is compatible with 2262/2260/1527/2240 and other chips with different encoding wireless remote control, can learn up to 12 wireless remote controller with different address code 433M operating frequency IV. Output mode setting (Note: Disconnect the power supply before proceeding to switch the working mode) A, self-locking - use short circuit to connect the JP1 position B, non-locking - short circuit vacant not connected C. - Use short circuit to connect the JP2 position V. Remote control learning method and inner code clearing method Click the learning button, the indicator light goes out, and press any button on the remote control until the indicator light flashes 5 times and stay long bright, indicating that the learning was successful. If the learned remote control is lost during use, it is necessary to clear the original information and then re-learn the same type of remote control. The receiving board can store up to 12 different encoded remote controls. Clearing method: Press and hold the code button for about 8 seconds, the indicator light from off to on, indicating that the stored information has been successfully cleared. Package Includes: 1 Piece Wireless Remote Switch Receiver 1 Piece Remote Control
