@Muhammed the PS_ON pin could be used for this purpose, but you must connect a flyback diode (the right way round!) in parallel with the relay coil, to protect the output from the coil back emf when you turn the relay off.

Alternatively, use a relay module instead of a bare a relay, then you should be able to drive from one of the pins on the expansion header.

@droftarts Thanks a lot, I had this in mind but wanted to see if there are other way to go around this. Using any output on the 50 pin expansion header would be fine, right?

@droftarts I really appreciate your support and thanks a lot 🙏 . This solved the issue perfectly.

@Muhammed correct. the paneldue port can provide more current than required for your diode

Great!. Thank you, I will give it a try

@infiniteloop Thank you so much for your reply. This will give me a push forward.

@droftarts Thanks alot. This was really helpful. 🙂
