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...
