6.2.7.5 Application Note
In addition to the notes in chapter 4, please regard the following:
 The voltage range of the analog inputs (10V variant) can be expanded by an external series
resistor in the input line. Thefore the input resistance of the board is exact 104KOhm, the
external resistor has to be also 104kOhm for every 10V range expansion.
e.g. for a range expansion to 0...50V you have to use a calculated series resistor of 4 x
104kOhm = 416 kOhm (use 390kOhm + 27kOhm of the E12 row). The filter behavior will not
be changed.
