3.5.13.2 Signal processing
Tasks of the operational amplifier
The Power Stack Adapter returns analog signals within a range of values from 0 V to 10 V to
the DM10 diagnosis module. Because of this fixed value range, signed signals such as the
actual speed value cannot be represented. Eight AD8674 operational amplifiers boost the
voltage signal (reduced by 5 V) by a factor of 2. As a result of this signal handling, it is also
possible to represent signals in a range of values from -10 V to +10 V.
