DATA CONVERSION
■ 0 – 100% DATA CONVERSION
Analog input data is converted into digital representations of 0 – 100% proportional to each scaled range. The converted %
values are expressed in signed 16 bits.
Overrange input is possible from -15 to +115% of the nominal range. When the signal exceeds the limit, the data is xed at
-15% or +115% respectively.

Analog output is converted in the reverse order of the input data. The output range 0 – 5V DC is expressed as 100.00 at
5.0V (100%) and 0.00 at 0V (0%).
