The DMP compact module 1I analog is used to input and digitize an analog
voltage value. This voltage value is measured by an isolated differential input.
In conjunction with the installed constant current source (2.5 mA), it is possible
to connect PT100 resistance thermometers.
The conversion time depends on the level of the input voltage.
Input voltage in the dimensioning range ––> conversion time < 60 ms
input voltage in the overshoot range ––> conversion time < 80 ms
The integration time is included in the conversion time, which determines the
noise suppression:
S 2 closed––> Integration time 20 ms 50 Hz noise suppression.
S 2 open ––> Integration time 16 2/3 ms 60 Hz noise suppression.
