Dear All,

We just measured the output of a 0-10V pin on an AIO module. We measure only 9.1V on the pins, instead of the expected 10V. In code, we set the I/O pin to value 10000.

I can imagine there is some margin for error, but this is almost a 10% deviation. In practice this means that we cannot run the attached pump motor at full speed if we wanted to.

How can I get the port up the the full 10V, please?

Hi Kees,

this is not as it ment to be. I did a quick test with a Core3 and an AIO on my desk and measured 10.01 V as expected. Could you please measure directly on the output pin (even without the grey connector)? Also the image version and pictory configuration would be helpful, to make sure it is not a hardware defect.

Dear Nicolai,

We measured with all wiring removed that the output was indeed 10V. The problem must be elsewhere in the system. Thank you for taking the time to confirm.

Thanks for the heads-up, Kees!
