I am attempting to use this
http://www.mcmaster.com/#6425k11/=vusltm as part of our Pneumatic system. When wired to the robot the solenoid does not function. The solenoid uses a input of 24V & 0.15A. 3.5 Watts.
We are using 3 of them which if I'm not mistaken would mean a total current draw of 0.45A ~ 450mA
