Digital Loggers 240V ethernet controlled relay switch.

  • Updated 9 months ago
I was talking with the Engineers at Digital Loggers asking about creating a box controlled via ethernet  that could switch one or two 240V AC lines. I am specifically looking to be able to switch the 240VAC power on/off to my Remote HF Amplifier.  They wanted me to email them with a description of what I was looking for and they would evaluate it and determine if there is demand for such a product to develop.  If anyone is also interested, please email me and i will include them with my "description" of what is needed.  Something that can be inserted in the 220V line without cutting or modifying the original power cable.   If you are "technical" minded and could describe what is needed in your own words, feel free to send along that info also.

 I am too old and sight impaired to be breadbording my own and so far have not found a solution in many searches.

Sorry for the Bandwidth..  Just thought any Hams with REMOTE station situations would be interested.

For the wording you basically you want one of these for 220V 20A:

What is the current handling of the outlets on the switchs from Amazon, looking at the outlets the Chinese one is 250V @ 10 Amps which is to small for the AMP. I think

and are both legs switched? 


For a DLI switch I would be game for a two outlet switch @ 220V 20A 
If there to expensive then I will just put a Double pole relay on the Switch I already have for the radio.

Thanks

You're right!

The one I referenced is only 10A... too small for my KW's. I was only suggesting this as the type I would like to see offered also. A two outlet version would also be ideal for me as I currently have two amps plugged into my custom two outlet box now.

Another company that makes one of these is https://www.synaccess-net.com/switched. But again it's only rated at 10A.

I think i'll just get a Relay and attach it to my existing 12V switch like this one or one similar.

the price is right anyway

I love the digital loggers folks, If you want I can drive over and talk to them. count me in as being as someone who things this would be a useful product.  N6WM

I love the digital loggers too.  I have a bunch of them.  But to switch 240 I think they will find it is not a big market.

So this is really not that hard to do with say a Raspberry Pi ($35) and something like this:

https://www.amazon.com/SSR-25AA-80-250V-24V-380V-Machinery-Control/dp/B01MZ2B0LA/ref=sr_1_2_sspa?ie=...

Which costs $9.  We'd just need 24V and a relay driver or FET to turn on the input.  That device can handle 25A too.  I haven't looked but there are probably others with more current ability.

It would be pretty easy to write a small piece of code that allowed you to turn on/off a relay from anywhere.

Just an option.  Certainly more work than going online and hitting the order button.

probably have to have two SSR to switch both legs of the 220V but a great Idea.

Use an ESP8266 wifi module and two SSRs and you could make it wireless for about $20.

I would like to make use of an Ethernet RELAY switch myself but am gun shy now. A couple years back a friend and I were using a Digital Loggers DIN Relay III to auto switch our SixPak antenna switches. My friend wrote a software that worked excellent with the Flex 6K until we discovered that model emitted birdies EVERYWHERE that it shouldn't be. No amount of choking would work, we killed and bypassed the internal switcher supply, Wasn't the switcher. Finally gave up. after it apparent it was hopeless.

They no longer make that unit DIN Relay III, it has been replaced with the DIN Relay IV. Hopefully that was something they may have addressed.


Anyway this is the unit to steer clear of

Https://www.digital-loggers.com/din3man.pdf


The switch units you guys are using now, have you widened your pan adapters and taken a close look?

Not looking to start something I'm interested to know if they are clean before I start another project like that one.


Thanks.

Clay, I was the developer that helped with that switching code and I bought a DIN relay unit too. It now sits idle on the shelf.

I use this one now for switching 120 VAC:

https://dlidirect.com/products/web-power-switch-7

It is in a metal box and so far I don't see a mega burst of birdees from it.

I don't know what you guys ended up doing for your switching but if you need to reopen that project I might suggest basing something around Raspberry Pi and relay board hats.

I'd be glad to help you guys with code to control those relays.  I'm using a number of Raspberry Pis now to do various things:

1) VPN
2) A control unit (I have a web page) that controls relays for on/off
3) A tuner controller

Well paint me old and losing it, sorry Mark totally slipped my mind that you are the guy Ken was working with. I said it had been a while back.
Well the code was sweet, solid. Too bad the device was so dirty.
Well now I am using the Denkovi 8 relay board with DDUtil. Also have a Genovation keypad working with it. I like DDUtil much more than I thought I would so it's a keeper for sure.

OK so I am now assuming these Ethernet relay AC power controllers are definitely clean, thanks for that info Mark.

The DLI switches are great. I use them for 120VAC control.

Consider an external DPST 240V relay with a 120VAC coil. Something like this: https://www.smarthomeusa.com/remote-controlled-heavy-duty-switch-60-amp-240vac-relay/

250 volt 50 amp DPDT with 12 volt dc coil and then just use something like one of the relays on a denkovi 8 relay board with Ethernet to activate the relay coil. I bought this relay for another project a few years ago for under $30 on ebay new and I am just waiting on an enclosure to put it in but its all wired up and works excellent with my QRO HF-2500 DX.

This was a temporary setup just to try it out until i get the enclosure, less bare wires the better.

Hmmm..  like this Larry..  Since I have a Microbit Webswitch 1216H with 5 rela control points this would easily work in a nice enclosure.

Count me in. Would be nice to switch power to the PG XL.

I use the DLI Web Switch Pro and use their AC Relay for Remote On and PTT on the Flex. 
The Auto Ping feature is nice to auto reboot PC, router, and cable modem if ping fails.

Thanks guys,  no promises...  just passed the interest and requirements along..    We shall see. 
Meanwhile I may look to build one using a 12V relay like W6LL Larry pictured above and controlling it with one of the spare control positions my existing Microbit Webswitch 1216H.

Nice setup Larry.  Understanding you used what was available.  We did the same but used a 120V coil relay.  That way it could be directly plugged into one of the Digital Loggers IP power strips and controlled remotely.

Good Idea, I have one of those digital loggers that would work excellent. I could still just use a simple 12vdc  wall wart supply plugged into the digital logger, i may try that.

K3MA:  Thanks John ..for some reason i never thought of that since I have both the DL Webswitch7and Microbit Webswitch 1216H  ethernet switching.  I order a DPDT 120vac coil 30A/250VAC relay off ebay for $10.00 to install in the box Larry W8LL listed..  This should work fine.  I estimate a total of $30.00 should finish this project off!
Thanks guys for all the good ideas.

Let me know how you make out. Might do the same here although I have the wife here most of the time :-)

I am planning to use the normally closed contacts and leave the DLI outlet off during normal operation.

Hi Dave,  Will do...  My Amp etc is away from here and I hate bothering the guy to reset this and that..  thus the project.   I use the DLI to control the remote PC, Astron Station PS and the Astron 12A PS I use for feeding 12V to the misc peripherals for RX antenna controls and Switching side of things. The DLI also power switches the Green Heron RT21 Rotor Control so I guess the PGXL main power is a natural progression!

Stay away from the "DLI DIN Relay" ethernet remote switch.  I have one and it works well, BUT it is loaded with RFI.  The RFI was so bad, that myself and others have hacked into the unit and disabled the internal power supply.   I then run external 5V DC into the unit to feed the operating circuits.  I have tried to contact DLI for a resolution, but no luck.  Brian - W9HLQ

Which DLI DIN Relay are you having trouble with, They have released 4 versions of the switch's 
the latest doesn't look like a brick, the first few versions where Tan color and there where some black one and now the latest ones are completely different which are on there WEB site.

Just needed to know which one is noisier then they should be. 
Thanks

Bret,  mine looks exactly like their web picture, DIN Relay III, black in color.  I guess the DIN means the relay is made to mount in a DIN rack.   I just placed mine on the shelf.  The unit is bullet proof with no false trips and I can control my station from anywhere.

The one on the WEB site is a Version 4 https://www.digital-loggers.com/din.html which looks completely different then the Version 3 https://www.digital-loggers.com/din3man.pdf   which are no longer being sold from DLI. 
I have a version 4 here I can check to see if they are noisy on HF bands still in the box.

Well, the DLI DIM Relay switches a set of 8 SPDT switches.  I use these to control the   Flex power on and also my remote antenna coax switch.  The PDU you mention looks like it can be used to control 120 VAC to shack items.   For that I use the Belkin WeMo internet relay.

Its 240, you can hook amplifiers up to it.

Would work great if 15 Amps is enough current to run the AMP at 2X1500 Watts output AND it is wired so that BOTH legs are switched off /on on the 240V outputs? 
There is a 15A circuit breaker so that limits the total current for ALL outlets draw to be 15Amps.

I know in the switches I have used here, DLI WEB Power Switch from version 1 to the latest version 7 that one leg of the input (white wire) was common and not switched with ALL the outlets and looking at the one you suggested has the exact same spec sheet for Power input and output so I would bet it's the same and so you will have one leg of the 220 Volt line HOT going into the AMP all the time which is NOT a good way to do it and would have 120V to ground, This leg is ALSO NOT Circuit breaker protected as the spec says only lists 1 circuit breaker. 

I have worked on the DLI WEB power switches and replace the switching power supplies in them and some versions have a lithium 3032 battery backup and some have EEPROMs  so I know how they are built inside so I would be cautious in using these in the USA for a power AMP as it could really give you a shock.

Best Idea would be to have a Remote power reset like the Radios have on the AMP to control a DPST relay in the AMP but until then I think the external DPST relay is by far the best solution that Larry has built.

Remember Europe and other countries uses 240V like we do 120V and that is why these are spec the way they are.  They don't have 2 legs with 120V on each like we do in the USA they have 220V on the Hot Lead a neutral and a ground. Look at this link for clarification on what I am trying to say
https://www.bluesea.com/support/articles/AC_Circuits/87/Differences_in_USA_and_European_AC_Panels

73's and just my opinion so proceed at your own risk with using single pole switch's.
