Description: Input voltage: DC12V RF frequency: 433MHZ Quiescent current: ≤ 10mA Material: Plastic Sensitivity: -105dB remote control distance: 20-200 meters or more (with different remote control supporting a different distance) the contact type: normally open relay normally closed passive contact contact capacity: ≤ 3A Receiver Size: Approx. 75x 55x 30mm/ 2.95x 2.17x 1.18inch Remote Size: Approx. 5x 4cm/ 1.97x 1.57inch Specification: The output mode is set by "Working mode selection cap". (Special reminder: switching work need to disconnect the power before doing) A, self-locking - take a short circuit to take the JP1 position (insert the middle of the plug and the circuit board inside direction); B, non-lock - take the vacant short-circuit connection is not connected; C, Interlock - Connect JP2 position by short circuit (insert the middle of plug and the direction of outside of circuit board); learning methods： Click the learning key, the light goes out, let go, press any key on the remote control until the indicator light flashes five times, indicating that the learning is successful. If you learn a good remote control is lost during use, you need to clear the information, and then re-learn the same type of remote control, so you can cancel the control of the previous remote control and obtain the right to use. The receiving board can store up to 12 different encoding remote control. Internal code clear method: press and hold the code key does not loosen for more than 8 seconds, the indicator light from off to light, said the stored information has been successfully cleared.
