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.
Analog output is converted in the reverse order of the input data. The output range 0 – 10V DC is expressed as 10000 at
10.0V (100%) and 0 at 0V (0%).
RESPONSE TIME
Response time of analog input module is time from when 0 to 100% stepwise signal change is applied to the analog module till when the communication ASIC of the module (slave) transmits 90% of input signal.
