Regarding the resolution of ETS-AO041I-E, what is the digital resolution corresponding to 4-20mA analog output?

You can find about resolution ETS-AO041l-E hardwaremanual show that this is 16bit.
As a result, all resolution of current output which is by 4~20ma, 0~20ma, 0~24ma is 16bit.
If you use small value between current output range, you can get more accurate value.

Thank you.
