Hello everyone,
This is my first time posting, but, beforehand, thank you all, you have answered many many questions I have had this last month or so.
I am facing a problem now, however, to which I could find no solution (and I don't understand what's wrong, to be honest).
I'm using a PCI-6259 card, which has 4 AO channels. Channels 0 and 1 are accessed through a SCXI-1302 (which is connected to a SCXI-1000 chassi) and Channels 2 and 3 through a CB-68LP board.
For my application I need a 4-20mA current output, which would be achieved indirectly by controling the output voltage (approximatelly 0-10V would do the job). However, there is a problem with my plan since it seems that the PCI-6259 output channels are limited to 10mA (10.46mA according to my multimeter, to be more precise). That means that after I reach that current level, even if I am not at 10V yet, it doesn't matter if I try to increase the output voltage: it just won't go up.
Is there a way I can get more than 10mA wiht this device?
Thank you all.
PS1: I have very limited knowledge on eletronics, most of it I have learned by myself, so bear with me! 🙂
PS2: I have seen on the PCI-6259 manual that the Overdrive current for the board is 20mA, but to tell you the truth, I am not sure what that means. I would suppose, though, that I could reach that current level by using a more advanced LabView programming.
