Long Range Control 4 LED Lamps—On to Many Series System

Question from customer:

I am looking for a long range (1000m theoretically) RF control. The transmitter can be 4 buttons. The receivers should be 12V DC models with 2 channels each and a remote antenna for each receiver.

Our answer:

We recommend 2 channel one to many remote control kit—S2UB-DC12+CB-4. 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. For the transmitter, we recommend CB-4 to you because the working distance of this transmitter can be 1000m when it pairs with the receiver. As your requirement, you want to add a remote antenna for each receiver. Certainly, you can choose external antennas for them (see the following pictures). 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.

We should prepare two receivers, one transmitter, 4 lamps, and 12V power supply.

This is the wiring diagram. According to the left side diagram, two led lamps are both connected to common terminals B of two relays and using wires to connect normally open terminals C of two relays. Then, two lamps is supplied 12 V power supply. On the other hand, we should offer power supply to the receiver. Do the same procedure for another receiver.

Press button A, turn on lamp 1; Press button A again, turn off lamp 1.

Press button B, turn on lamp 2; Press button B again, turn off lamp 2.

Press button C, turn on lamp 3; Press button C again, turn off lamp 3.

Press button D, turn on lamp 4; Press button D again, turn off lamp 4.

Wirelessly Romote Control Water Valve by Sprinkler Controller

Question from Customer:

I am trying to design and build a remote switch system for my sprinkler system. I need to use the sprinkler controller (12v output for on) to trigger a transmitter to switch a 12v operated valve on the other side of the yard (about 300m away.) I have mains power at both locations but the underground 12v wire from the controller has been damaged so I would like to build a remote system to save putting new conduit for around 300m across the yard.

Looking at your systems, the easy part would be the receiver end because I would only need a 12v power supply. The hard part will be getting the transmitter to switch on when the sprinkler controller switches on (12v).

Answer:

We recommend direct power output high power long range remote control kit—S1PX-DC12-ANT2+CB-2V. The remarkable feature of this kit is that its transmitter is triggered DC power 5~28V input. That is to say, the transmitter will send out RF signal to receiver as long as it gets a 5~28V voltage from a device. Besides this advantage, its working distance is up to 2000m (6000ft). And the working current is 30amp. RF signal can pass through doors, walls and other obstacles.

Look at the following simulated diagram. The sprinkler control controls the valve box through the underground electrical wire initially. Unfortunately, the wire has been damaged. However, customer is unwilling to put new conduit for about 300m across the yard.

So using our product to solve this problem is a wise choice. We connect the black wire of transmitter to the common wire of sprinkler controller; Connect the red wire of transmitter to wire from controller to valve. On the other hand, in the control valve box, valve common wire is supposed to be connected to the negative terminal of receiver; valve wire should be connected to the positive terminal of receiver. (As the following application circuit shown)

When you switch on sprinkler controller, the transmitter will be triggered by 12V voltage from sprinkler controller and sent out RF signal to indicate receiver to work. The valve is open and it starts the irrigation. Likewise, you switch off sprinkler controller, the triggered transmitter will indicate receiver to stop working. The valve is closed and it stops the irrigation.

There is no need to put new wire between sprinkler controller and valve control box. It is no longer the hardest part of getting transmitter to switch on when the sprinkler controller switches on.

Wireless Automatic Garden Watering System and Remote Control Lamps

Question from customer:

Can you help me select the correct product? The distance is 600 feet through house with walls and some trees. I need to turn on a 220 volt garden watering system for my plant. There is a solenoid valve connecting to the spray head of the system. I also want to turn on at least three other dc 12 volt circuits separately for lights.The control panel has a switch on it right now that I would like to be able to still use if necessary.

Answer to this question:

We recommend this four function distant-range rf remote . The working voltage range of relay is AC 110—240V or DC0~28V. The highlight of this product is that it can activate different electrical devices with different working voltage simultaneously.There are totally four channels. It is 10amp current for each channel. The working distance is up to 2000m (6000FT) in open air with external mount antenna. It is very appropriate for garden watering system.

We make a demonstration of this remote controlling.

Let’s look at the following material.

As seen in the picture, three spotlights should be connected three relays’ normally open terminal individually and be supplied DC 12 V power supply. The pond fountain will be connected to last one relay’s normally terminal and be supplied AC220V power supply.

There are 4 buttons on the transmitter. One button controls one relay. Usually, we set “Toggle Mode”.

So press button “A”, turn on the led light strip 1.

Press button “B”, turn on the led light strip 2.

Press button ‘C”, turn on the led light strip 3.

Press button “D”, turn on the solenoid valve.

Press buttons one by one again to switch off all of them.

Grant Range Remote Control is used in Metal Shed Warehouse

Our grant range remote control, S1PUA-AC220-ANT2 & CB-2 was purchased by one of our customers recently. He said that he was so happy with the items because of its good performance. What’s more, he also satisfied with our fast delivery and product tracking service.

That customer said that it is more importantly for remote control kit is to work well even in his metal shed warehouse. For installation of a device controlled by remote controller in his house, that customer also has tried other brands’ RF products but none of them can work as well as ours.

The receiver is high power with maximum working current of 30A. It has three working modes which are toggle mode, momentary mode and latched mode. The RF signal can pass through walls, doors, floors, trees and so on. With the external mount antenna, the receiver pairs with long range transmitter-CB-2. Remote control distance of transmitter & receiver set is up to 2000m in open field.Thanks to this external extend antenna design, it enhances RF signal’s transmitting and makes excellent performance.

The wiring is not complicated. Just do as the following picture.

Lamp or other devices should be connected to normally open terminal A&B at first. Then we wire up the receiver. Press big button on the transmitter, the lamp or other devices will on; Press small button on the transmitter, the lamp or other devices will off.

Voltage Input Triggered Remote Control Design to Applying to Device Control another Device

I need a device that can connect to an existing 110V light switch. When the light switch is ON, the device sends a wireless signal to another 110V outlet to turn on a light that is plugged into that outlet. When the 110V light switch is OFF, the device turns the outlet off.

A：

This device, which is pointed out above, is more likely our brand new product, CB-2V. The characteristic of the transmitter CB-2V will be triggered by DC power 5~28V input.

According the requirement from customer, we will try to give a demonstration of our 1 channel 2000M voltage input triggered rf remote control set to show how it works.

Material preparation:

1 x transmitter, CB-2V

1 x receiver, S1X-AC220-ANT2

2 x lights

1 x adaptor

1 x power strip

Power supply

Let’s see the wiring procedure.

Step 1

We connect the transmitter to the 12V adaptor and plug lamp 2 to power strip.

Plug the transmitter to power strip.

Step 2

We connect lamp 1 to the receiver and connect the plug to the receiver.

When pressing the button on the power strip, the lamp is on and the transmitter CB-2V sends a wireless signal “ON” to the receiver S1X-AC220-ANT2, it will make another lamp on.

When pressing the button on the power strip again, the lamp is off and transmitter CB-2V sends a wireless signal “OFF” to the receiver S1X-AC220-ANT2, it turns another lamp off.
