Description Overview:   The wireless receiver controller has the characteristics of high confidentiality, large storage capacity, stable performance and low power consumption, and is easy to use. It does not need to adopt traditional jumper or dial-code switch encoding. It only needs to receive and store the wireless signals transmitted by the remote control to realize the supporting use. If the learned remote control is lost in the process of use, the information stored in the receiving controller should be cleaned up. The lost remote control will not be able to remote control the receiving controller. In order to regain the right of use, the user must learn again before using it. It is mainly used in the fields of electric door, window, lifting equipment, gate, elevator, industrial control and security.   Way of working:    DC-12L has five working modes: signal self-locking, signal interlocking, signal non-locking, signal self-locking and non-locking coexistence. 1. Signal self-locking -- press the remote control number 1 button 2. Signal is not locked -- press the remote control number 2 button 3. Signal interlock - press the remote control button 3 4. Signal 1~6 way self-locking and 7~12 way non-locking coexistence - press remote control 4 key 5. Signal 1st self-locking and 2~12 way non-locking coexisting - press remote control 5 key   Output method:   1. Signal self-locking: press the remote control button 1 Press the remote control No. 1 button, the relay corresponding to the No. 1 button is pulled in and held, and then press the No. 1 button again, the No. 1 relay is disconnected; Press the No. 2 button of the remote control, the No. 2 button corresponds to the relay is pulled in and hold, and then press No. 2 key again, the 2nd relay is disconnected; the 3~12 key works according to this cycle.   2. Signal is not locked: press the remote control button 2 Press and hold the remote control No. 1 button, and the relay corresponding to the No. 1 button is pulled in. After the hand is released, the relay is disconnected. Press the No. 2 button, and the relay corresponding to the No. 2 button is pulled in, and disconnected after being released; 3~12 button Work as usual.   3. Signal interlock: press the remote control button 3 Press the remote control No. 1 button, the corresponding No. 1 relay is pull in and held, press the No. 2 button, the No. 1 relay is disconnected, and the relay corresponding to the No. 2 button is pulled in and held; the 3~12 button works according to this cycle.   4. Signal 1~6 way self-locking and 7~12 way non-locking coexistence: press remote control button 4 Among the 12 relays corresponding to the remote control, 1 to 6 are self-locking functions, and 7 to 12 are non-locking functions.   5. The signal 1st self-locking and 2~12 way non-locking coexistence: press the remote control button 5 Among the 12 relays corresponding to the remote control, the first one is a self-locking function, and the 2~12 are the non-locking function.   Note: If the learned receiver need to change to other functions, please clear the receiver and select the required button to re-code the code.   Learn method:   When the receiver is powered on, press the learning button on the receiver to light up and release, enter the learning state; according to the function you need to select a key to learn by the remote control, the receiver flashes one time (the buzzer sounds once) means that the study is successful.   Clear method:   When the receiver is powered on, press and hold the learning button on the receiver for about 8 seconds until the indicator light goes out (the buzzer sounds for about 3 seconds), indicating that the code has been successfully cleared. This receiver can store about 30 different remote control codes.   Technical parameter:   Working voltage: DC12V/DC24V/AC220V (Optional) Quiescent current: ≤7mA Working temperature: -20 ° C - +70 ° C Receive sensitivity: ≥-107dBm Operating frequency: 315MHz to 433MHz Control voltage: AC, DC optional Output current: ≤5A Board size: 120mmx73mmx18mm Shell size: 125mmx78mmx30mm   Industrial 12-key remote control parameters:   Working voltage: DC6V (4 batteries on the 5th, the battery is not included) Quiescent current: 0mA Working frequency: 315MHZ/433MHZ (Optional) Chip Type: Fixed Code (2264) Oscillation resistance: Default 475  Launch distance: 200-500M (open environment) Modulation method: ASK amplitude modulation Size: 70 x 158 x 38mm   Package includes:   1 x Receiver 1 x Remote control Shipping information (1) FREE Shipping 10 - 15 business days, (2) Standard Shipping 7 - 12 business days.
