Hi all

Please suggest suitable 3 wire current measuring (4-20mA)analog input module for S7-400H.

Thanks in advance.

Hi, 

See manual SIMATIC S7-300 S7-300 Module data on page 360 for example.

I hope I coule help!

Thanks microman for your valuable feedback.

I have SM331(6ES7331-7KF02-0AB0) module and I would like to connect a 3-wire 4-20mA transmitter to this module.

How I can connect it?

Thanks in advance for any help.

Hi, 

The manual SIMATIC S7-300 S7-300 Module data page 360 show you an example for that. 

I hope I could help. 

Hello,

sorry for my intrusion.....

but 6ES7331-7KF02-0AB0 connection for 4-20mA is in page 372 of the manual.

Also look at page 381-382, you have to choose the correct position for hw measurement range module (position C for current).

Last question...

in first post you say you have s7-400h...

do you have some im153 slave modules to mount 6ES7331-7KF02-0AB0??? 

Best Regards

Thanks mindware

Yes  I have IM153.
