Solid State Relay ?

[fred97]

hello everybody ,

i have domoticz interfaced with mysensors , i'm very happy but i need to use SSR like thiss : http://www.dx.com/fr/p/ssr-25da-25a-solid-state-relay-white-134494#.VTuG0iHtmko .

but i have no signal , juste to power with 3,3v the side DC of m ssr ...

thanks in advance .

@fred97 If you apply 3.3V power, it will close the circuit between the AC terminals, so you can consider the + side the signal and connect - to ground. The + side would then connect to an output on the Arduino and you would turn on the SSR by bringing it high. You could also wire it the other way around (- to an output on the Arduino and + to 3.3v) and then turn the SSR on by bringing the output low.

One thing to confirm is how much current the DC side of the SSR draws to make sure it's within the limits of what the Arduino can supply. Most SSR will draw less, but I would measure it just to be safe.

Cheers

Hy

How can I control it? arduino nano + nrpf24 +two pin ssr 25 da relay modul ?? Domoticz.

This relay two pins + and -. Mysensors how to HIgh and LOW pin arduino.

Thank you in advance for your reply.

@szempo I built a controller using ssr's , it was a while ago but you may get some ideas from the post.

AC Power controller with node to node remotes

This is it!
Thank you very much
