Help Prop-1 Board Not Working

[alphachi]

I think I may have popped a component on the board, I can no longer detect the Prop-1 on my USB. The board worked fine with the 24v power supply until I loaded the program below:


I am using a 24v DC power supply to trigger 5 different 24 volt air solenoids :


Is there anything noticeably wrong with the code?

Are the power and V+ LED's lit? Hard to tell from the photo but it does appear the cap circled is burned. At any rate, a bad program wouldn't cause your situation.

[alphachi]

Yes they still emit light but I think the board is dead. After rereading the instructions, I should have connected the solenoid to one of the outputs and the V+ Terminal. If I connected the outputs to the ground terminal, would that cause the board to fail?

[JonnyMac]

No. The OUTx terminals are open-collector and connect to ground. Open-collector means they act like an open circuit when not active, and then they switch to ground when activated; connecting ground to ground is not a problem.

I have PM'd you with instructions to return the board to us for repair -- it's not something you can do in the field.
