Hi,

I lost in the the system configuration, i dont know which devices, and accessories need I.

I have to do a pid control., I need NI 9237 daq to receive the signal from the load celland NI usb 6216 daq to control a pressure relief by the received signal by 9137. I need also a full labview development system. thats ok.

But is there anything? I dont understand why need i chassis and controller?

With just Ni 2937, 6216 and labview, can i do this regulation?

You need at least a single slot chassis to plug the module into to get the clocks, etc and the ability to communicate to it with your controller. The controller could be your pc that you've also plugged the 6216 into.

kThanks!

and May I have an other question? I should create a connect between a DAQ and a pressure relief, liek this. Is there any adapter to connect them? 

Thank you.

Impossible to say from just an image. You should read the manual to determine the type of signal(s) it requires. You'll probably need one of the NI terminal blocks to connect with some discrete wires.

This pressure relief can receive 0-10 V, but i am not an expert, so I attached the manual. Could you help me?

It just has an analog input and a ground. Connect an analog output of the DAQ device (i.e. ao0) to the input of the valve and ground of the DAQ device to the ground of the valve.
