[c]FP-SG-140

I am using a cFP-SG-140 for strain gauge measurement.  Can I use the left over channels to measure non-strain gauge analog voltage input?

Hello,

It is not a good idea for you to use the other channels to measure analog voltage.
Each channel on the module contains an excitation line and two input lines that measure the resistance across the strain gauge.  The internal circuitry that is present on each channel to acquire the inputs from the strain gauges makes it pointless to measure analog voltages. 
You can take a look at the manual to see information on the circuitry for each channel.

I recommend that you use an analog input module to perform your voltage measurements.

Take care!
