Near Intersection of I-35 & I-90 Southern Mn. | Yes, a relay might help. I have no experience with the Ipaq but, it sure shouldn't take much current to trip it ON/OFF.
I would actually be more concerned about the Ipaq itself. PF3000's have been fried when people have tried to do what you have described.
It is always safer to use a relay that the spray system trips rather than feeding power directly to the device. |
