No. Analog input range setting

User range setting
*1 If an analog input value exceeds the range of digital output value, the digital output value is fixed to the maximum or minimum value.
*2 Set the offset value and gain value in the user range setting within a range satisfying the following conditions. Failure to satisfy the
conditions may not result in proper A/D conversion.
Gain value  24mA, offset value  0mA
((Gain value) - (Offset value))  15mA
*3 Maximum resolution in the user range setting
Analog input range setting
4 to 20mA
0 to 20mA
4 to 20mA (extended mode)
User range setting
• Use the values in the solid line region in the graph of current input characteristics. If a value in the dotted
region is used, the resolution and accuracy may not fall within the range of the performance specifications.
(Set values within the practical range of the analog input and the digital output at each input range.)
• Do not set the voltage over 30mA. Doing so can cause breakdown of the elements.
