Hi all,
When configuring S7300 analog module with 4-20 mA range, there is an option called Measuring Type, and I should choose 2DMU or 4DMU. I understood that this means 2 wire or 4 wire transmitter.
If I'm using a 2 wire transmitter, then I don't have to provide power for the transmitter if I choose 2DMU ??
And what is the difference between 2DMU and 4DMU ??
Thank you
