Hi,
I am using a ni 9265 analog current output with a cdaq 9185 to control a small 4-20 milliamp driven valve.
I haven't successfully got it to output current yet, I was hoping I could get some help to verify I am doing things correctly:
wiring:
1. +24 V from power supply to Vsup on module
2. ground from power supply to COM on module
3. wire 1 from valve to AO1
4. wire 2 from valve to AO2
VI: (see attached)
1. DAQmx create channel AO-current-basic outside while loop
2. inside the while loop DAQmx write analog double 1 channel 1 sample
3.control wired to the data input that ranges from .004 to .020
I set up the task for analog output current for the module in measurement and automation explorer.
Thanks!

Sorry, typo in my original post by mistake:
3 & 4. the valve was wired to AO0 and AO0 ground
