RF Remote Control Blog

Someone would like a remote control to switch on and off his lamp via controlling a contactor. He drew a picture to illustrate his idea. Maybe it is not so convenient to him to remote control lamp directly, so he choose to control his lamp via a contactor. We recommend him a 1 channel AC remote switch with memory function (S1MU-AC220+C-2). This 1 channel ac rf memory remote controller operates in toggle, momentary and latched control mode (set the mode as you like freely). With function of memory, if the power is cut off, the relay will return automatically to the previous status after the power is restored. It is great for hard to reach lights or other electrical devices, remote distance up to 100m (theoretically). It is applied to control lights, motors, fans, electrically operated doors / locks / windows / blinds / cars or other appliances with voltage AC 110~240V or DC 0~28V. According his requirement, we have this following diagram. Initial state: A, B = Normally Closed; B, C...

When you want to remote control one more AC devices, you may think about 2 channel remote receiver. This kind of Latching 2 channel remote switch (S2L-AC110~240V + C-1) may be suitable for you. It is activated by AC110V~240V power supply, so being controlled devices will get power from powered receiver. The maximum current output is 3 ampere. The Coding type of receiver is learning code. You can remote control any electric devices within 100M (No obstacles). Look at the following wiring diagram. We try to introduce 2 lamps controlling of this kind. First, we connect the neutral wire to the terminal “1”, and the live wire to the terminal “2”. Second, we connect the lamp 1 to the terminal “5” and the neutral wire. Third, we continue to connect the lamp 2 to the terminal “4” and the neutral wire. Latching mode is the only working mode of this remote. So we can do the following operation. 1) Press button C: Turn on the lamp 1, turn off the lamp 2. 2) Press button B: Turn on the lam...

The 1 channel Latched mode RF remote control operates in AC110V ~220V and 315/433MHz. Through retrofitting, this kind of remote control made a little changes compared with the original remote. Two kinds of receiver style, one is AC 110V (AC 100~120V), widely used in US, Canada…; the other is AC220V (AC 200~240V), used in UK, France…. The Coding type of receiver is learning code. Maximum working current for each channel is 3 ampere instead of 4 ampere of original one. The working distance is 100M. You can control on/off, open/close of universal electrical devices. Applications include gate remote control, motor remote control, garage door remote control, light remote control, etc. We will take ac light remote controlling for an example. Look at the following wiring diagram. From the interior analogue circuit, we connect the neutral wire to the terminal “1”, and the live wire to the terminal “2”. And then connect the lamp to the terminal “5” and the neutral wire. Latched mode is the ...

Question from customer: I was hoping to be able to use a device to turn on my heating and light at home when I am at work. Answer: We recommend you wireless telephone remote control module (TC-01). You just need to make a telephone call, you can remote control your home appliance when you are at work. It can control variety of home appliances and electronic products in any place worldwide by fixed telephone or mobile phone. The range of application is lights, TVs, motors, fans, cameras, video/ audio signals, electrically operated doors/ locks/ windows/ curtains/ bell or other equipments with voltage AC 110~240V or DC 0~48V. It also has password protection which can avoid being used by other people. Here is the wiring diagram and picture. Telephone line is plugged into the telephone socket on the telephone remote control module. Remote control module should be supplied power. Connect heating and lamp to two relays. Operation method: 1)Dial the number of fixed telephone at your...

Question from customer: I want to use the remote control to replace the button of my contactor. Since the switch will be activated rarely, is it possible to test the communication with the remote to be sure that the transmitter’s battery and receiver work correctly? Answer: We came up with a good idea that it can replace your manual switch to remote control contactor and to test whether the transmitter’s battery and receiver work correctly. So we recommend normally open/ closed 2 channel AC remote controller (S2U-AC220+C-2). The normally open/closed contact terminals are applied to universal power supply. In other word, normally open /closed contact terminals are as a switch for device. You need to supply DC or AC power to your controlled devices. The maximum current is 10ampere for each channel and its working distance is about 100m. We got a plan for your problem. At first, it is the wiring. Look at the following wiring diagram. A&B terminals are the normally closed term...

If you want to remote control 2 devices temporarily, our retrofitted momentary 2 channel remote switch (S2M-AC110~240V + C-1) may be very favorable for you. It is activated by AC110V~240V power supply. The maximum current output is 3 ampere instead of original 4 ampere. The Coding type of receiver is learning code rather than fixed code. You can remote control any electric devices within 100M(No obstacles between transmitter and receiver). Look at the following wiring diagram. We try to introduce 2 lamps controlling of this kind. First, we connect the neutral wire to the terminal “1”, and the live wire to the terminal “2”. Second, we connect the lamp 1 to the terminal “5” and the neutral wire. Third, we continue to connect the lamp 2 to the terminal “4” and the neutral wire. The power for controlled lamps is output from powered receiver, so you don’t have to supply any power for controlled lamps. Operation is as follow. 1) Press and hold button 1, turn on the lamp 1; Release but...

The 1 channel RF Momentary Remote Control (S1M-AC110~240V & C-1) features in AC110V ~220V. There are two kinds of receiver style, one is AC 110V (AC 100~120V), widely used in US, Canada…; the other is AC220V (AC 200~240V), used in UK, France…. The Coding type of receiver is learning code. Maximum working current for each channel is 3 ampere. The working distance is 100M in the open air. Momentary mode is the only working mode of this remote. We can use this kind of remote control to control AC motor on and off. For instance, the garden irrigation system, hot water circulation system, water pump and so on. Those motors just need to be turned on and off. Look at the following wiring diagram. From the interior analogue circuit, we connect the neutral wire to the terminal “1”, and the live wire to the terminal “2”. And then connect the motor to the terminal “5” and the neutral wire. Momentary mode (Press and hold button -> On; Release button -> Off)) All you need to do is ...

Question from customer: I want to run a 12V dc winch that uses a car battery for power. I also want to run a small 9 volt dc motor. And small motor is powered by small calculation power supply. I wonder if there the remote controller which can be used for those two motors which need two different voltages to supply to rotate in forward and reverse direction. Answer: If you want to remote control 2 motors’ back and forward, you need 4CH normally open/closed contact remote control kit (S4C-DC12+C-4). Each relay can only activate motor run at one direction, so 4 relays can realize 2 motors to run two directions respectively. This 4CH RF wireless remote control switch operates in toggle, momentary, latched and toggle + momentary control mode (set the mode as you like freely). You can also use it to complete four operations at the same time. But For example, turn the light on, open the door or control other dc/ac electrical devices in the meantime. It is applied for light remote control...

Question from customer: What I am looking for is a controller with 220v input voltage, operating 2 relays simultaneously. One relay will open and close 220v, and the other relay open and close 12v. Push button once – ON, push button again – OFF. Can this RF controller be programmed so that both relays open and close with one same button of the remote controller? Answer: We recommend the normally open and closed contact remote receiver and one-button transmitter (S2U-AC220 +C-1). This normally open and closed contact is as the switch of device, that is to say, you can supply AC or DC power to the controlled device. And we can set two relays to work with only one button by changing the software. Suppose we control one alternating current lamp and one direct current lamp simultaneously with one-button transmitter. This is the wiring diagram. A&B terminals is normally open, B&C terminals is normally closed. We usually connect lamps to normally open terminals. So 2 lamps are c...
