Hi,
I need to drive a field device using analog ouput signal from Labview/NI. The local vendor quoted me NI 9264, which is a -/+10 V output module. But my field device takes 4-20mA signal. Is there a way to convert the voltage to mA? Or does NI have 4-20mA Analog Ouput card/module?
Thanks for your help

One option is to use a industrial converter module with 0-10V input and 4-20mA output. Reliable industrial stuff, usually with the benefit of additional galvanic isolation.
