Easy to install Web Relay

Tim and I have been searching for a Web relay that would work world wide.

We found the SonOff 4 Channel Pro relay that is available on Amazon World Wide and at very good prices.

There seems to be a few versions of this switch, but the one I tested had 4 SPDT Switches

The device is powered by 9-24V DC or 90-260VAC. The one I have requires a Canon connector for the 12V I used, but others may have a quick connect terminal. You should have no issue powering it from a Wall Cube that you already have in a junk box.

The one I tested was the V2 and I was able to use it to connect to the Remote RCA connector on the back of the radio for soft power up and power down.

I also used a 2nd contact for PTT should you ever need to do a remote SmartLink registration.

They make many versions of this, but you want the one that shows the NO/NC contacts as on the bottom of the case.

It does require that you use the eWeLink app on your SmartPhone (I only tested on iOS). https://www.ewelink.cc/en/

I did a very basic schematic that you can reference. R1 turns the radio ON and OFF and R4 would do a 1 second PTT to the radio. You need to set R4 for 'inching' and you do that in the eWelink application.

I found that on the one I had, I had to open the box and change some dip switches.

S6 had to be set to 1 and K5 had to be set to all 1's (closest to the relays).

I have yet to test it beyond basic functionality, but there does look like there is a bunch of Node-RED flows for it as well.

Just another solution for the toolbox!

    Can the same wiring diagram also be used for my Flex 6300??

    Im using a webswitch for the same purpose..... Controlling my Flex 6700 and controlling coax-relays

    5 channels that can Switch 16A/230VAC

    The good thing is that I only need a webbrowser to control it and do not need to run another app in my phone.

    Have a look here: https://www.webswitch.se/wp/

    ControlByWeb makes an assortment of easy to use relays with IP connectivity. I use two of them in my shack. One controls larger relays for amplifier power on/off. The other one controls my antennas disconnects.

    When you add the remote PTT are you just adding an RCA Splitter and using the PTT RCA Port for both?

    Im looking to set up the remote power ON/OFF for my 6600. The post by Mike is now 6 years old so Im wondering whats the latest on this. There are so many new mainstream (Amazon) sellers and potentially many small shops new, in the recent years?

    Im also looking to turn on/off the TGXL and a PGXL.

  • Raul Pla

    Would this device permit the power On and off to the PGXL? I could split the current into 2 of the 4 20A relays so the PGXL has up to 40A at 240V. I would use a third relay for the remote on/off control of the 6600. Am I thinking this right?
