4 to 20 mA, 0 to 20 mA, 0 to 10 V, −10 to 10 V, 0 to 5 V, −5 to 5 V, 1 to 5 V, 0 to 1.25 V, −1.25 to 1.25
V (separate for each input), and ±10-V user-set range (specified range within –10.000 V to 10.000
V)
It is possible to scale process data. (Any minimum and maximum values can be set.) (2 inputs set
separately.)
Data can be converted at 0% to 100%.
The value derived from carrying out the following processing in order of the actual process data in
the input range is output as a 16-bit integer (INT).
1) Mean value processing → 2) Scaling → 3) Zero/span adjustment → 4) Square root calculation
→ 5) Output limits
