💬 AC-DC double solid state relay module

[Nca78]

That's where the biggest problem is on this board. I think the previous revision without the DS18 is safer, here there is less than 2mm creepage/clearance between main and low voltage traces and solder points, not enough :(

There's also problem of mixing both main/low voltage everywhere in the board like near the NRF24.

Hi
Noob questions sorry !
1/ Can i used it with 3way switches ?
2/ what are the pins 7 GND and 4 for ?

7 and 4 pins are mapped to 7 and 4 in/out of an arduino module. GND is for ground. These pins could be used to manually control relay state.

@mr_const ok i understand ! Thinks

hi, great project. I have one idea, is it possible to add current and voltage measurement ?

[Sander Crombeen]

Ordered all the components for this project but now i see there are 12 v solid state relays on the list?? mine is not working, does it not need to have 5V version??

[Achim]

Hello,
one question to the SSR Relay. The Arduino works with 5V, the SSR in the BOM is a 12V type. Is this a mistake? According to the Datasheet of the relay, the 12V type has an operating range from 9,6v to 14,4V

[mr_const]

@Achim looks like a mistake in BOM (maybe that aliexpress listing has changed). Project uses same relay, but 5V version is needed.

Hello all,

I have finished to assemble one of this board today.

You can see some pictures of my board here :

If you want more pictures, ask me ;)

The skecth works fine.

Thx for this project.

Avesome photogallery :smile:
whose sketch you used? because I have a problem with phisycal switches if I use sketch of Nca78 (I wrote about this earlier)

[tonnerre33]

I used the sketch of Nca78 (2 months ago) but i only command relays from jeedom.
I didn't test physical switch change because i don't have neutral wire in my switch box :(

Sorry Okos I didn't notice the problem came from my sketch. I'm not using the physical switches at the moment (same reason than tonnerre33, no neutral wire where I have put it at the moment), but I will try to find some time next week to fix the sketch. I'll fix the temperature sending too as sometimes I have some tiny variations of temperature that generate a lot of message sending in a burst and it perturbates other sensors.

@tonnerre33
Just a quick question before i order the PCB, is it realy 4.6x5 cm? (thats what it says on the dirtypcb website, but when i mesure the PCB in the diptrace file, it shows a perfect 5x5 cm.
can you please explain?

[Nca78]

PCB is 5*5cm.
You will also have to include the antenna of the NRF24 that is outside the PCB area.

[tonnerre33]

Yes, it's 5x5cm.
For information, i can't place this pcb in my wall box.
I'll search other wall box this week in order to find a greater box..

If someone want just to test the PCB i can sell one PCB if you are in france ;)
I have ordered 10 boards but i don't think use everything.

Same here if you are in Vietnam or asia, just pay postage and I can send you :p
I have 20 as first order from Seeed took too long to arrive I thought it was lost, so I ordered again from PCBWay. Then received both orders.

@tonnerre33 what is the space available in your wall box ? Would a 43*45mm pcb fit ? Only one relay/switch on my future board but phase + neutral in and phase + neutral out so no need to have additionnal connectors. No SMD, safe distance between tracks + milling. And 0.1'' tracks for load so it should be ok without reinforcing the tracks with solder.

[br0wn]

@tonnerre33 Thanks buddy,
do you know if dirtypcb are still operational? because i've seen in their website that they want to migrate to another website "dangerousprototype"
did anyone order from them lately?

[Nca78]

@br0wn dev.dangerousprototypes.com is supposed to be a test site only, dirtypcb is still functional.

@Nca78

Merci ^^

[tonnerre33]

@Nca78
I have searched others wall box today but nothing fit (box from france).
A 43x45mm pcb will fit well.
I tried the pcb of the roller-shutter-node (45x46mm) and the wall box fits well.
What do you mean by "no additionnal connectors" ? Will can use physical switches ?
