One Device Control Another Device

Long Range Communication System (Remote Control Application)

Question from customer:

I need a remote valve setup for a nitrogen purging system.The valve is 100volt 10amp that needs to be controlled by latching switch setup. I’ve seen many setups everywhere that will work but my problem is that I need some sort of indications, such as a led lamp or something at the remote to verify whether the valve is open or not. Do you have something like this available?

Feasible solution:

We found a solution to solve your problem. We also made a simulation test.

You need feedback to the remote or another receiver with a signal light to verify remotely that the valve is open. We’d like to prepare two sets of remote control and make them a remote control group. The main system is 1 channel 12VDC output receiver (S1XL-DC12)+ long range transmitter (CB-2). The secondary system is still 1 channel 12VDC output receiver (S1XL-DC12) , but we use dc triggered transmitter (CB-2V, triggered method DC power 5~28V input), which is applied for one device controlling another device. 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.

The following picture is the material preparation.

When you add the external extended antenna, you will make the remote controller working distance to 2000M in the open air.

Here is the wiring diagram.

The wired transmitter (CB-2) will work with Receiver 1 as one group. The wireless transmitter (CB-2V) will work with Receiver 2 as another group. We have a wired remote transmitter at the first receiver that it will remotely turn on a lamp at the second receiver near the wireless transmitter.

Operation:

Press big button of wireless transmitter (CB-2), send “ON” RF signal to the first receiver, turn on lamp 1(blue lamp) and trigger wired transmitter (CB-2V), wired transmitter switch on lamp (red lamp) on the second receiver.

Press small button of wireless transmitter (CB-2), send “OFF” RF signal to the first receiver, turn on lamp 1 (blue lamp) and trigger wired transmitter (CB-2V), wired transmitter switch off lamp 2 (red lamp) on the second receiver.

We can get feedback through red lamp to verify whether the controlled device (Blue lamp) is working or not.
