Hi everybody,

I am searching for  optimal confitguration to our water treatment project. I have one thing in my mind and i cant find it over internet.

If i decide to put many et200s io modules; how many power modules do ı need, is there any progrom-tool-excel table or something like that for these know exact number of power modules for ets200s line?

hi,

try to use TIA Selection Tool. It says you when the consumption is to high.

TIA Selection Tool

See this thread for further information. 

ET220S

It depends on what you are running on the modules, how much current the respective devices need.

hope this helps,

regards,
