Hi all,
I am using NI cDAQ-9174 and NI 9203 analog current input module. I want to use two turbidity sensor whose output are 4-20 mA. I will wire the two negative lead of the turibidity sensors into one and connect it to the COM. The positive lead of the turbidity sensor number 1 will goes to the AI0 and the positive lead of the turbidity sensor number 2 will goes to the AI1. Am I correct?
The wiring diagram of the turbidimeter model 850 is attached below.
Thanks.

Hi Tritran,
It looks like you already have an answer, but if you're looking for more information on 4-20 loops, we have an article that goes into a bit more depth on the topic: here's a link.
