Hi Robin,
I would do that if the manual didn't say the boards are ready for inductive
loads (and now Peter ratified that too) or if I'm too close to the max
current threshold. But I really want to keep this as simple as possible at
this final stage. I was worried because I was used to solenoids
Hi Peter,
400 mA per output should be OK unless you have mode than 3 outputs on at

That's excellent news. One less thing to worry about :)

I'll do that.
Thanks Peter for the quick

Personally, I would wire up some external driver simply to avoid any
accident with the 7i72 ... optos would be involved if it was me.

Hi guys, I hope you're all doing
Hi guys, I hope you're all doing great
This could be probably for Peter but most of you will know the answer so
here it goes.
I have to drive some 24 VCC pneumatic electrovalves and I would like to use
7i72's outputs directly. Each valve consumes 400 mA and the 7i72 max
current per output is 300
