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 multiplied by 100 and expressed in 16 bits.

Overrange input is possible from -15 to +115% of the nominal range. When the signal exceeds the limit, the data is fixed at

-15% or +115% respectively.

•Input Range 0 – 5V DC

Analog output is converted in the reverse order of the input data. The output range 0 – 5V DC is expressed as 10000 at

5.0V (100%) and 0 at 0V (0%).
