<Initial value of scaling for each output range>
Output range Initial value of scaling Available range of scaling (See note.)
0 to 5 V 0 to 16000 0 to 25000
1 to 5 V 0 to 16000 0 to 25000
0 to 10 V 0 to 16000 0 to 25000
-10 to 10 V -8000 to 8000 -25000 to 25000
4 to 20 mA 0 to 16000 0 to 25000
0 to 20 mA 0 to 16000 0 to 25000
Note 1: Scaling is enabled only when the operation setting switch on the module rear panel is set to “Soft Set Range Operation
mode”. In fixed range operation mode, scaling is disabled.
Note 2: Over range is fixed to “(Gain value - Offset value) x 0.025 + Gain value”.
(“(Gain value - Offset value) x 0.0125 + Gain value” for the range of -10 to +10 V)
On the other hand, under range is fixed to “Offset value - (Gain value - Offset value) x 0.025”.
(“Offset value - (Gain value - Offset value) x 0.0125” for the range of -10 to +10 V)
Note 3: If scaling results in “resolution < maximum resolution”, digital output value does not change in steps of one.
Note 4: Once scaling values are set, they won't change even when range is changed.
