Looks like they call for the 1M to insure linear accuracy of the sensor. Since you are really only interested in is it running or not running, probably does not matter. Noticed that the spec says Max Signal Out 12VDC. Maybe a spike is possible. Might be best to stick with one of the opto-isolated Inputs which have the 30 VDC upper limit. Don’t know what a 12V spike might do to the ANx Inputs.
