["Description:\nbrand new and high quality\nFeature:\nRemote Control:\nThe four-way remote control switch is a very widely used wireless control device. It uses microprocessor intelligent control. It can be used in garage door control, lighting control, remote control curtains, electric door locks, wireless doorbells, etc. It is simple, safe and reliable.\nThe remote control switch has a small volume, and is suitable for remote control of access control systems, wireless modification of garage doors, intercom doorbells, remote control of car trunks, and wireless control of household appliance switches.\nThe receiving sensitivity is high, the remote control is more than 50 meters away from the open ground, using fixed code wireless coding technology, no direction, and the switches do not interfere with each other.\nReceiver:\nThe relay contacts of the receiving board output independently, which is very suitable for directly controlling various loads.\nAdopt fixed code wireless coding technology, no direction, and the switches do not interfere with each other.\nThe circuit board on the receiving board has enough materials, and the power supply part of the circuit board uses a professional-grade switching power management chip, which has stable performance, low power consumption and high performance.\nThe fuse resistor and varistor can effectively protect the circuit board, which greatly improves the service life of the entire remote control switch.\n\nSpecifications:\nItem Type: Receiver+Remote Control\nMaterial: ABS+Metal\nSize: receiver: 108x66x29mm/4.2x2.5x1.1in, remote control: 61x29x12mm/2.4x1.1x0.4in\nColor: Black\nFrequency: 433MHZ\nWorking voltage: AC85-250V\nRemote control distance: 20-100m or more (open space)\nOscillation resistance: 820K\nContact capacity: less than and equal to 7A\nCoding type: fixed code (2272 series chip), pad code\nOutput mode: four-way normally open and normally closed passive contact output\nQuantity: 1 Set\n\nInstructions:\nControl the wiring of AC220V load:\nThe load receiving board for controlling lamps and lanterns generally chooses the self-locking working mode, the relay works independently and does not interfere with each other. Press the remote control button to pull in the corresponding relay. If you press the A button once to turn on, then press the A button again to turn off, B, C, D are the same, the four channels can be turned on and off independently. It is effective and does not affect other relays. It can remotely control 4 channels at the same for time. It is recommended that each channel should not exceed 200W.\nControl DC12V voltage wiring:\nIf you need to control other voltages, just change the DC12V in the figure below to other voltages. If you control the load receiving board of lamps and lanterns, you generally choose the self-locking working mode.\nRemote modification of garage doors and electric doors:\nThe receiving board generally selects the non-locking jog working mode. The electric door has three manual buttons of \"open, close and stop\", and the three buttons of the remote control control the three pairs of contacts and three pairs of contacts of the three relays of the remote control receiving board. Received on the \"on, off, stop\" manual buttons respectively. The four-way remote control receiving board is provided, and three of them can be used. The for extra one can be used or used as a backup.\nRemote control modification of the speed switch of the electric fan:\nThe receiving board generally chooses the interlocking working mode, the interlocking mode is that the relay alternately pulls in. If you press the A button, A is connected and locked and for always connected, then press the B button to disconnect A, B is connected and locked and for always connected, C button, D button and so on, four-way interlock, only one way to connect Pass; here press the D for key, which is the fourth way for the stop for key. At this for time, no matter which way ABC is connected before, press the D for key, the previously connected will be disconnected to achieve the stop function.\n\nNote:\nNo retail package.\nTransition: 1cm=10mm=0.39inch\nPlease allow 0-1cm error due to manual measurement. pls make sure you do not mind before you bid.\nDue to the difference between different monitors, the picture may not reflect the actual color of the item. Thank you!\n\nPackage Includes:\n1 x Remote Control\n1 x Receiver"]
