Omron SSR with 3.3V node
-

Guys,
I like the Omron G3MB-202 SSR
So far I have used these on 5V arduinos
I am now moving on towards my next project (touch wall switch) and would like to go for 3.3V nodes
Any of you using these SSRs with 3.3V trigger ?
Thanks a lot for your return ;) -
Hello @ben999,
I have not had any problem with those relays (at least the cheap clones from aliexpress) when running the full board at 3.3V (using HLK-PM03).

Thank you for sharing your experience
There are resistors and transistors on the relay board... I guess the relay is triggered via a transistor then...
Do you run the relay itself (black bloc only) straight from the arduino output? -
@ben999 yes, directly connected. I suppose transistor is here for the case when your board signal voltage is too low compared to the voltage of the SSR as the necessary current for SSR is low.
