SSR on the IO ports - which pins to use?
-
Hello everyone,
I need to connect 4 x SSR's to my Duet 6HC and would like to use the IO_5–8 ports to switch them on (I assume this is possible?).
My question is:
Which pins from the IO goes to the + and - of the SSR?
Apologies if this is very easy, but so far I have not been able to find a straight answer.

If 3.3 volts will work (it's pretty close to the min value of 3) just connect the plus terminal of the SSR to the 3.3V on IO_5 (or any other IO_#) and the minus terminal to IO5.OUT.
If 3.3 doesn't work you can use the 5V_EXT if the jumpers are set so that a source of 5V is feeding those pins. Normally this is the case and the internal 5V supply is feeding those pins.

True, I think i'll go with the 5V just to be sure.
Thank you so much Frederick! -
