Appendix 1 I/O Conversion Characteristics
Current output characteristic
The following shows the list of the analog output ranges and the graphs of each current output characteristic, at the current
output.
*1 Set the offset value and gain value in the user range setting within a range that satisfies the following conditions. If the following
conditions are not satisfied, D/A conversion may not be performed properly.



0mA, gain value



((gain value) - (offset value))

11.3mA
*2 Maximum resolution in the user range setting.
• Set values within the practical range of the digital input and analog output at each output 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 current output characteristics.)
