2000m Range Wireless Receiver with 4 Relays of Remote Control by 1Channel Transmitter

Question from customer:

I am looking for a transmitter/receiver system with a range of at least 200 m that will allow the activation of at least three or four commands at the same time and then trigger three or four relays on the receiver at the same time. Most systems only allow for one command at a time even though they have the capability of 2 – 12 relays activations. Do you carry such a transmitter/ receiver system?

Answer:

This is wireless remote control device model: S4C-DC12-ANT2 & CB-1 which we introduce to you. The receiver (S4C-DC12-ANT2) has 4 relays in it and the transmitter (CB-1) just has one button. You just need to press the button, then it will trigger 4 relays in the receiver at the same time by wireless remote control.

It can control lights, motors, fans, electrically operated doors/locks/windows/blinds/cars or other appliances with AC110~240V or DC 0~28V. After you connect the appliances to the relay in the receiver, you push the button on the transmitter and it will launch wireless RF signal. The signal will be received by the receiver. Then the relays are activated at the same time. And you can turn on/off the appliances through wireless remote control. Besides, the wireless remote control device’s working distance is 2000m/6000ft theoretically because of the receiver with external extend antenna (ANT2) as following picture:

The wireless remote control device just has one control mode because of the 1 channel transmitter. You can set the control mode toggle as following circuit board picture: you just only connect jumper-2, then press the button on the transmitter, the relays on; press the button again on the transmitter, the relays off.

Here is the circuit diagram. You can connect appliances to the terminal of the receiver. Then supply power to the receiver. When you press the button of the transmitter, you can turn on/off the appliances at the same time by wireless remote control.

So the wireless remote control device can be used to control four same appliances by triggering four relays in the receiver at the same time. If you would like to know more something about the product, please enter into our website and search the product as following:

Wireless RF Remote with learning code control AC and DC Devices

In our daily life and work, we need a variety of electrical devices. Some need AC voltage supply, and some need DC voltage supply. If we want to remotely control one DC voltage appliance and the other AC voltage one simultaneously. What do we need for this? Model 0020497 (S2U-DC12& C-2L) is more suitable compared to other types of wireless remote controls.

The remote control includes two parts, the receiver S2U-DC12 and the transmitter C-2L. The relay of the receiver can work at AC and DC voltage, so we can select one AC voltage device and the other DC voltage one, two AC voltage devices, or two DC voltage devices.

The remote control is widely used. It can control lights, motors , fans electrically operated doors/locks/windows/blinds/cars or other appliances with AC110～240V or DC 0～28V. We can remotely control electrical equipment by wireless RF signal that can pass through walls, floors and doors. The remote control is very helpful, we can move and carry it to any place we want to go because of its wireless and lightweight.

The distinguishing feature of the remote control is with learning code function. There are millions of codes to learn, so it is much safer for us to use. In the factory, there is a fixed code in the transmitter. The receiver can get the code by learning function. If we want to use several receivers in the same place at the same time, the receiver can be set different codes . If we don’t want the transmitter to work with the receiver, you can delete the code that stored in the receiver.

 

We learn how to learn and delete the code on the basis of the application circuit below.

The procedure of leaning code:

1) Press the button of receiver; signal LED on the receiver keeps shining. The receiver enters into status of LEARNING.

2) Press any one button on remote control. If signal LED flashes quickly 15 times and turns off, it means learning is successful.

3) When receiver is in the status of LEARNING, press again the button of receiver, signal LED turns off, learning process will be discontinued.

4) The receiver can learn several remote controls with different codes.

The procedure of deleting code:

Press and hold the button of receiver until signal LED flashes slowly; release the button, LED keeps slow flash. That means all stored codes have been deleted successfully.

Look at the diagram above, we can learn how to wire on the basis of it. The terminals A and B are normally closed, the terminals B and C are normally open. Output terminals Positive electrode and Negetive electrode should be wired to additional power supply. Two appliances (a DC lamp and a AC lamp) and their DC power supply or AC power supply should be connected to the terminals B & C.
