The specification sheets for the SDC2130 define the absolute maximum input voltage for the Din as 15V (p. 6) and on page 8, under the sensor signal spec, it says the digital 1 level is 3-15V.
However, the NxtGen manual seems to define the max input voltage as 5V.
Will running with a digital 1 at 12V cause any short or long term damage? This is in line with the spec sheet but not, it seems, with the generic manual.
12V would be much more convenient in my circuit.
thanks,
