Issue Details

I want to work with a Load cell which needs 10V as the excitation voltage. Can NI 9219 support external excitation?

Solution

The NI 9219 only supports internal excitation, and cannot accept an external excitation voltage or perform Half-Bridge and Full-Bridge measurements with no excitation. To use external excitation, National Instruments recommends NI 9237.
