Snap IDC5Q quadrature

Dear I hope you are well. I came here to ask for your help, I work with the opto 22 snap pac controller, I use a hard court module, These modules are already 5 years old but over time they are burning as you can see on Photograph. The power, therefore, comes from a 5-volt source, but the GND is connected to other GNDs from other sources. the question is whether the burn could be due to the connection of the GNDs?

Welcome to the forums!

Do you have a photograph of the modules to attach?
It would be helpful to see what you are seeing.
Also I am not sure what sort of module you have… You mention a ‘hard court module’… that description does not match any of our current SNAP PAC modules.

Please reply to the forums, not to my personal email… More people will see the post and can offer help.

Here are the two photos;

Sorry to take so long to get back to you, we had to chase up some people from the factory to help understand whats happening here.

Could you please provide or photograph the module date code?
Thanks.

dear Beno,
I hope you’re okay. Here are the pictures. If you need more information, I am at your disposal.

Are you seeing the photos? I think they didn’t look good.

Yes, I can see the photos clearly.
Thanks very much for attaching them. Very helpful.

I heard back from the engineers… That date code is before a hardware change.
Please contact our support group; https://www.opto22.com/support and take this up with them.
