1 Channel AC Remote Controller for Contactor

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 = Normally Open. Wire contactor to normally open contact B&C terminals. And Wire a lamp to contactor and install a switch for lamp (See the original picture).

There are 3 working mode of remote control. They are toggle, momentary and latched modes. We suggest that he should set latched mode because this remote works with a 2-button transmitter.
Setting control mode Latched: Do not connect Jumper-1 and Jumper-2.
Control mode Latched: Press -> On, another relay Off; Press another button -> Off.
Press button 1: Turn on the contactor to turn on lamp (connect B and C, disconnect A and B)
Press button 2: Turn off the contactor to turn off lamp(disconnect B and C, connect A and B)

Remote Control 2 Lamps 100M 3 A—Latched Mode

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 lamp 2, turn off the lamp 1.
3) Press button A: Turn off the lamp 1 and the lamp 2.
You can remote control any AC electric appliances other than lamps. It is very convenient to you because you don’t have to supply any power to controlled appliances.

Latched Mode Remote Controller for Lamp Controlling

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 only working mode of it. As regards the latched mode, it is motivated by relay group. (Latched (Press button 1-> On; Press button 2 -> Off)) So we prepare a 2-button transmitter for you to remote control it. All you need to do is just press slightly the button on the remote. You press button 1 to turn on lamp; press button 2 to turn off lamp.
