Russell,
The lowest input range for the AIO-600 is 0-6V. This means you will have 12 bits (11.3 effective) of resolution spread over 6 volts. I take it your full scale signal max will be 36mV. Without amplification you will not have a very high quality signal. The best bet would be to amplify your mV output signal as close to the load cell as possible and then connect this amplified signal to your AIO-600.
Best,

Russell,
Chris LS is correct, you need to condition the signal. You can build your own using something like an AMP02 as the front end and a LF412 to buffer output signal. Or you can purchase something like this . Several companies make similar products. Cheaper that buying a new cFP I/O module.
Hi,
You will need a loadcell transducer that can convert the loadcell (bridge) output to normal voltate (-10 to 10V) or courent (4-20mA) output and then you can connect it to to your hardware.
