One of our customers wants a simple wireless remote operate 4 led lamps from several room at his house. He needs 4 transmitters and a receiver which can be mounted in a designated place. The remote must work from receiver about 50m away and not line of sight through doors and walls. We suggest him choose dc 4 channel remote control system  (S4C-DC12& 4C-1). Maximum working current is 5amp each relay. Working distance of remote and receiver set is about 100m (300ft) in open field. This 4CH 6V9V/12V/24V wireless remote switch operates in toggle, momentary, latched, toggle + momentary control mode (set the mode as you like freely). Easy to install and operate. Just press slightly the button on the remote, you can control universal DC/AC electrical devices. The RF signal can pass through walls, doors and other barriers. As he said, we will set 4 transmitters and this receiver with same 8-bits code in advance so that they can work together. Operation modes: 1) Setting control ...

Question from customer: Whether we can get the receivers with different voltage versions? For example 2 piece of 24 volt and 2 piece of 240 volt. Answer: Yes, it is possible. We recommend those two kinds of receivers—for 24V version, it is 24V DC input receiver (S2UB-DC24). For 240V version, it is 100V~240V input receiver (S2U-AC220). Both of them have two relays on the PCB. So there are four channels totally for your devices. They can pair up with long range transmitter (CB-4). It can control lights, motors, fans, electrically operated doors/locks/windows/blinds/cars or other appliances with voltage AC 110~240V or DC 0~28V. Owing to normally open& closed contact, you should add additional power supply to your devices besides your receivers. But you can do as following wiring method to save power supply adaptors. Wire devices (lamps) to B terminals of each relay, using wires to connect devices to output terminals of each receiver. For dc input receiver, we supply dc 24v p...

Question from customer: I need a unit that can receive from four transmitters, and switch 4 relays. Each transmitter controls each channel. Answer: We recommend the model of 4 Transmitters and 1 Receiver Kit (S4C-DC12 & 4C-1), which belongs to “One-to-many series”. “On-to-many series” include one-transmitter-to-many-receiver system and one-receiver-to-many-transmitter system. It is often used for controlling two or more electrical devices in different places by one transmitter; or one electrical device by two or more transmitters. If you want to remote control one device with different transmitter from different places, this kit is your better choice. Here is the wiring diagram for your reference. The receiver is normally open & closed contact. A,B terminals are normally closed. B,C terminals are normally open. So you can wire your devices to B terminals and negative terminal of power supply. And add DC 0-28V or AC 110-240V to your devices. Supply DC 12V to receiver. ...

Question from customer: I’m looking for a wireless remote that I can use to create a simple on off switch to 12 led light fixtures connecting to a 6V battery at different places around my home. Do you have any suitable remote controller for me? Answer: We recommend model 12 Channel DC6V Remote Controller – 1 Transmitter & 12 Receiver  (12S1UB-DC06&1CV-12). This RF remote controller has the special ability to learn remote codes, allowing it to be used in one-transmitter-to-many-receivers system. That is to say, you only need a transmitter to control 12 receivers. 6V is added to receiver as activated power. It operates in toggle, momentary, and latched mode (set the mode as you like freely). It is great for hard to reach lights or other DC/AC electrical devices, remote distance can be 500m (theoretically). And it is applied for controlling lights, motors, fans, electrically operated doors / locks / windows / blinds / cars or other appliances with voltage AC110~240V or DC...

One man has 4 small lighted exterior signs around a pharmacy building and would like to control all four signs to go on and off by a simple RF system switch. He is wondering whether this is possible or not? He can order 4 receivers for light control model of S1X-AC220-ANT2 and one long range remote transmitter CB-4. All lights are respectively installed to each receiver for longer remote distance. The theoretical transmitting distance is 2000m (6000FT) in the open field. Even though in actual operation, it is hindered by trees, walls or other obstacles, or interfered by other signals. It is still enough for the exterior signs around the building. 4 lighted signs should be wired to 4 receivers’ L&N terminals individually. Wiring diagram as shown below: Press button “A”, switch sign 1 on and off. … Press button “D”, switch sign 4 on and off. Online shop:  http://www.carymart.com/
