I have a UR10 industrial robot arm that I'd like to communicate with using it's IO board with my Pi 3B. I would like the arm to perform a pick and place routine after I detect that some operation is done with the Pi.

Its IO board has a 24V 2A control box. I was thinking that some solid state relays as a 3.3-to-24V level shifter would suffice. This does not have to be instantaneous communication, just a toggle.

    This answer as presented looks like a (minimal-effort) product endorsement. Looking deeper suggests it's not, but that's not quite the point.

You are right; relays are your friend. A little bit of poking around found a relay HAT at Amazon. I haven't tried this and will not benefit if you try it, but the specifications look right and the reviews are good. I like the idea of a HAT for your application because you have a sort-of one-piece controller. https://www.amazon.com/Raspberry-Pi-Expansion-Module-XYGStudy/dp/B01G05KLIE I am sure there are other suppliers for this or something similar.
