New 12v wireless remote control switch module 2 way controller 4000 meters long distance 12 volt | Инструменты

---

Features:   1>. Long distance 4000 meters: The high-frequency three-level signal amplification tube is used, which is farther away from the 3,000-meter remote control on the market. 4000 meters is the theoretical distance. The general open-air remote control distance is between 1000m and 3000m ( The environment is different, the distance is also different, the actual use depends on the size of the environmental disturbance), and the distance will be shortened in the case of obstacles.   2>. High sensitivity: The signal receiving adopts the real superheterodyne RXB8 module, the sensitivity is -114dBm, the sensitivity and anti-interference ability are far beyond the super-regeneration on the supermarket surface and the ordinary super-heterodyne module, the remote control distance is farther and more stable.   3>. Output relay switch: It can control the load of different voltages below 270V, and it is flexible and versatile.   4>. Small volume: small size, circuit board size is only 46*38*20mm.   5>. The working mode is freely adjusted by the user: the user can modify the self-locking, interlocking and jogging working modes.   6>. Learning type code: You can learn the code with the same frequency remote control at will. (Don't worry if you lose the remote control during the process. Just buy a remote control and learn it. It is OK, no need to replace it, which greatly saves the user. cost).    

 

 

 

Receiver board size: 46*38*20mm       Product introduction:        The company's remote control receiver board is suitable for electrical control circuits such as anti-theft alarm, remote control electric door and window, signal control, industrial control, lifting equipment. All remote control switch module relay contacts are independent output, which is very suitable for direct control of various loads; the product adopts fixed code wireless coding technology, no directionality, and the switches do not interfere with each other. 12V remote control switch, the power supply is recommended to use more than 500mA DC regulated power supply. The anti-interference ability and receiving sensitivity of the superheterodyne module are much higher than the ordinary super-regeneration module.       The receiver board can withstand 10A per channel and can directly drive AC loads. Each relay has a set of normally open (normally closed) contacts. In order to extend the service life of the receiving board, the company does not recommend controlling the high-power load. When controlling 220V, each channel controls 500W, and when controlling 12V, it controls 50W each channel.       Basic parameters:   Product model: KGS-B20-4   Working voltage: DC12V   Working frequency: 315MHZ   Contact capacity: ≤10A/250VAC; 10A/30VDC   Receive sensitivity: >-114dB   Remote control distance: 4000 meters (no interference in open space) This distance is the theoretical distance without interference,                   In use, it will be reduced according to different environmental disturbances and partition walls. Generally nominal                   10%-50% of the distance.   Number of control channels: 2 normally open (normally closed) contacts.   Coding type: learning type; space pair code.   Learning method: Press the learning button once, the indicator light is on. At this time, press the button on the remote control, the indicator light goes out and the learning is successful.       Clearing method: Press and hold the learning button for 8 seconds, the indicator lights up, then goes out, and the clearing is successful.   Working mode: (interlock/jog/self-lock, user can jump cap selection on the circuit board, factory setting is self-locking)                    Interlocking, (by pressing each key of the remote control, the corresponding relay is turned on, and then press another remote control button; the corresponding relay is turned on, the other is turned off, and only one relay can be turned on at a time. This mode of operation can be purchased. The 4-button remote control is usually used to control the motor's forward and reverse rotation. Please specify or contact customer service when purchasing.)                    Jog (press each button of the remote control, the corresponding relay is turned on, release the remote control button; the corresponding relay is disconnected, 2 independent control,)                    Self-locking, (the same key control all the way, press once to open, press again to close, 2 independent control)
