ni 9265 wiring and VI (cdaq)

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!
