Input conversion characteristics

An input conversion characteristic of A/D conversion is expressed by the slope of the straight line connecting the offset value
and the gain value at the time when an analog input (voltage or current) from outside the programmable controller is
converted to a digital value.
Voltage input characteristic
The following shows the list of the analog input ranges and the graphs of each voltage input characteristic, at the voltage
input.
No.
Input range setting

0 to 10 V
(2)
0 to 5 V
(3)
1 to 5 V
(4)
-10 to +10 V
*1 When analog input exceeds the range of the digital output value, the digital output value is fixed to the maximum or minimum.

• Set values within the practical range of the analog input and digital output at each input range. If the values
are out of the range, the resolution and accuracy may not fall within the range of the performance
specifications. (Do not use values in the dotted line region in the graph of voltage input characteristics.)
• Do not set the voltage over 15 V. Doing so can cause breakdown of the products.
