One LED Lamp Automatically Control Another


This rf remote control transmitter & receiver 0020521 (S1XL-DC12-ANT2 & CB-2V) can be used in such a situation when you want to use an electrical device to remotely control another device. It features in long distance and direct power output functions. Remote distance is 2000m (in open field). The input and output power are the same as DC 12V. Easy to wire and operate. 

Next we will explain how it works in detail.

 We take one led lamp as the original device, the other one as the device being controlled. The transmitter has two extended wires. They are connected to the original led lamp to send out rf signal. The receiver is for receiving the signal. The led lamp being controlled is connected to the receiver. When the original led lamp is on, the led lamp being controlled will be switched on automatically.

Firstly, choose one led lamp to be the original device. Solder the red wire on transmitter to the output terminal “+” of the lamp and the black wire to the output terminal “-”. Since the led lamp need the power to work and the transmitter need the input power to be triggered, the power supply should be soldered together with the lamp and the transmitter.


Another led lamp is supposed to be the device being controlled. Wire the led lamp to the output terminal (A&B) on receiver. Wire another power supply to the input terminal on receiver, so it can supply the power to the receiver.


Plug two power supplies to the power socket.

Switch on the power. The original led lamp is turned on and outputs DC 12V voltage. The transmitter is triggered and then transmits an rf signal “ON” to the receiver. After the receiver receives the signal, output terminal (A&B) outputs DC 12V voltage; the led lamp being controlled will be switched on automatically. Long sentences to describe the operation but the whole process is just in a second.

Switch off the power. The original led lamp is turned off and stops voltage output. The transmitter is triggered and then transmits an rf signal “OFF” to the receiver. After the receiver receives the signal, output terminal (A&B) stops voltage output; the led lamp being controlled will be switched off automatically.

Short Description of Toggle / Momentary / Latched Working Modes

Generally there are three working modes for rf remote controls: toggle, momentary, latched. Toggle mode is used most often. Controlling lamp, for example, press the button of remote, turn on the lamp; press the button again, turn off the lamp. Momentary mode can be set to control rolling blind or rolling door. Press and hold the button of remote, open the blind or door; release the button, close the blind or door. Both toggle and momentary mode are motivated by single relay, which means you can work these two modes with single button remote. As regards the latched mode, it is motivated by relay group. For relay group, only one relay will be on at a time, e.g. press remote button A, relay A will be on, and relay B will be off; press remote button B, relay B will be on, and relay A will be off. To be more specific, when you control the lamp by latched mode, you should prepare at least two buttons remote. Press button A, the lamp is on; press button B, the lamp is off. Online s

Remote Control Electromagnetic Lock

Image
Electromagnetic lock is a locking device that consists of an electromagnet and an armature plate. The principle behind an electromagnetic lock is the use of electromagnetism to lock a door when energized. Essentially it consists of an electromagnet attracting a conductor with a force large enough to prevent the door from being opened. That is to say, if only we could cut off power supply and make electromagnet force between electromagnet and armature plate to disappear, the door would be opened. Furthermore, we just try to use a direct dc output momentary remote and one button transmitter to cut off electric power to open the door. The following demonstration will show. At first, we prepare material. The wiring When we supply power to electromagnetic lock, electromagnet will attract armature plate through magnetic force. The door is locked. When we press button, the power supply will be cut off. The door is open as soon as electromagnetic lock unlock instantly. What’s more, t

How to Make Motor Rotate in Positive and Reverse Direction by High Power Remote Control

Image
We are going to demonstrate that our 30 A high power remote controller controls high power motor to rotate in positive and reverse direction. This kind of controller is activated by dc 12v power supply with 30 A current output of each relay. It is very favorable for high power device. It also has four working modes including toggle mode, momentary mode, latched mode as well as momentary + toggle mode. First of all, let’s see material preparation. 1 x 2 channel dc high power remote control receiver (S2PU-DC12) 1 x 2-button remote transmitter (C-2) 2 x dc12v power adapters Some lines Secondly, see the wiring diagram below, B is normally open terminal; C is normally closed terminal and A is common terminal. Connect terminal C to the positive and connect terminal B to the negative. Terminal A is supposed to be connected to the motor. Note: The Power supply of receiver and motor must be provided individually in order to avoid interference between them. Switch on the power O
