I am looking to purchase a PCIe-6363 board and I need to be able to read thermistor data using it.
Currently, with a separate USB DAQ (a USB-6212), I am reading thermistor data by creating a voltage divider circuit, measuring the voltage and then mathematically calculating a current which can then be converted to a temperature. In this setup, I have +5 V from the DAQ to a 10 kΩ resistor and then that is tied to the thermistor and AI 0 and the other end of the thermistor goes to AI GND. (I'll try to add a diagram as an attachment.) This seems to work fine.
With my new system that I'm planning on purchasing, I was thinking that I would connect to the PCIe-6363 using two SCB-68A accessories. I will have 8 thermistors that I need to read (as well as other devices that are already outputting a voltage) and was hoping to build these circuits on the board. It looks to me like I can use the analog input pads to accomplish this, but I'm not 100% sure what the correct way to wire this would be. I'm using Figure 2-3 from the SCB-68A User Manual as a reference. For whatever reason, I'm a little confused as to what is going on at each of the pads.
It seems to me that one end of my thermistor would go to the AI0 screw terminal. The other end could go to an available AI GND screw terminal. Then it seems to me, that I would put my 10 kΩ resistor in the left hole of A and the left hole of F. However, in examples further in the manual, nothing is ever connected to the left hole of A. I don't want to damage anything, and I want to make sure that these components will work for my needs before purchasing them.
Does this sound right? Thanks
