Driving solenoid with PXI-6514

[dphan128]

Hi,

I'm trying to verify PXI-6514 digital output function by driving a 12VDC solenoid. When energized the voltage measured across the solenoid is only ~7.00VDC. Why I'm having a drop in voltage ? Please explain.

I'm connecting +12VDC supply to P7.VCC and P7.COM and output to P7.0 and P7.COM.

Thanks

Dan

Dan,

It sounds like it is connected correctly.  What if you measure across P7.0 and P7.COM without being connected to the solenoid.  Also, have you tried any of the other lines on P7, or any of the other ports?

L. Allen,

Without connecting to the solenoid, I can see 12VDC across P7.0 & P7.COM. So I moved the connection to other lines, and sure enough I can see ~11VDC across the solenoid. There must be something wrong with P7.0 line.

Thanks for the tip.
