RF Remote Control Blog

Question from customer: I need a 2 channel receiver with 2 remotes 1 channel. One remote control activates the channel A receiver on the receiver and another remote to turn on the channel B on the receiver. Is it possible with the CWB-1 model? And which receiver would like to recommend? Answer: We recommend 2 channel12V multi-mode receiver (S2U-DC12) and two waterproofwireless 50m remotes (CWB-1). We set configured code for them so that they can work together. The receiver is 12V activated and has two relays. When it works with that transmitter, its transmission distance can reach 50m in the open air. There is only one button on each transmitter. It can control lights, motors, fans, electrically operated doors / locks / windows / blinds / cars or other appliances with AC110~240V or DC0~28V. You can turn on/off the receiver with transmitter (remote control) from any place within a reliable distance; the wireless RF signal can pass through walls, floors, doors...

Question from customer: I am looking for a transmitter and receiver with at least 3 buttons (4 max ) to be used to open and close my gate. I don’t know which is better RF or UHF? Do you have anything that can work for me? I will do the electronics all I need is the option to latch or momentary relay outputs. Answer ： We recommend 4 channel 12V multi-mode remote controller (S4C-DC12+C-4). It operates in toggle, momentary, latched and toggle + momentary control mode (set the mode as you like freely). You can use it to complete four operations at the same time. 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, motor remote control, garage door remote control, gate remote control, etc. We think this remote can be used for controlling gate. That is to say, you can use this remote control to control one or two motors of your gate. To realize gate opening and closing, one motor needs two relays ...

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 12V battery at different places around my home. Do you have a recommendation for which Wireless remotes or RF transmitters may be the best for the task at hand? Answer: We recommend model 12 Channel DC12V Remote Controller – 1 Transmitter & 12 Receiver (12S1UB-DC12&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. 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 A...

This 2 Channel RF AC Remote Controller is driven by AC power supply, which operates in toggle, momentary, latched and toggle +momentary modes (just set according to your requirement).It is very favorable for DC/AC electric devices which are hard to reach or far away from switch. It is widely used for lamps, doors, garage doors, motors and so on. Working voltage range of relay is AC 110~240V or DC 0~28V. The Maximum working current of each channel is 10amp. Sometimes, it’s not ideal and convenient to get someone to go back and forth to turn this device on/off, so remote control is your better choice. AC power supply driven remote controller can also control AC motor. We will try to show you how to control positive and reversal rotation of an AC motor with this remote module. Let’s see the following material. 1×2CH RF AC receiver 1×2-button transmitter 1×AC motor Power supply Here is the wiring. There is difference with DC power supply activated remote control. Terminals L&N...

The receiver is designed for one-transmitter-many-receivers system. There are two channels for each receiver. You can use 2 receivers with transmitter CV-4 or CB-4. You also can choose external antennas for them. With the extended external antennas, the transmitting distance will reach about 2000m in the open air. This kit is also a multi-mode remote control which includes four working modes, toggle, momentary, latched and momentary+toggle. Online shop:  http://www.carymart.com/
