Hello, I have a 3 wire 24VDC solenoid for air. ![20240105_141206](https://us1.discourse-cdn.com/flex020/uploads/universal_robots/original/2X/e/ed9f2d6d2df901073cc47f84715d807c1e1c0ecc.jpeg) The green/gold ground would go to the 0V, 1 would go to the 24V PWR on the grey Power block, and 2 would go to DO0 right? Any insight would be greatly appreciated as Iā€™m new to UR! Thank you! ---

Green must go to earth (not a terminal in the controller, but one of the earth/case screws). 1 to DO0 and 2 to 0V (the other way around should work as well, though). šŸ™‚ Now, the connector has a rating of 4A - what is the current rating of your solenoid? FIY, The UR controller can only supply 2A of current. ---

.125 Amps. Wiring it up like you said worked! Thanks efn!
