Remote Control:
The 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.
The 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.
The 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.
The relay contacts of the receiving board output independently, which is very suitable for directly controlling various loads.
Adopt fixed code wireless coding technology, no direction, and the switches do not interfere with each other.
The 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.
The fuse resistor and varistor can effectively protect the circuit board, which greatly improves the service life of the entire remote control switch.

Control the wiring of AC220V load:
The 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 time. It is recommended that each channel should not exceed 200W.
Control DC12V voltage wiring:
If 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.
Remote modification of garage doors and electric doors:
The 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 extra one can be used or used as a backup.
Remote control modification of the speed switch of the electric fan:
The 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 always connected, then press the B button to disconnect A, B is connected and locked and always connected, C button, D button and so on, four-way interlock, only one way to connect Pass; here press the D key, which is the fourth way for the stop key. At this time, no matter which way ABC is connected before, press the D key, the previously connected will be disconnected to achieve the stop function.
