Hello, Could you recommend an Analog input/output module to be used with ET 200SP. Those modules need  to be galvanically isolated. 

Hi buwa,

it may depend on what you would like to read.

There are different options for resistance/thermo couple or 0-10V/4-20mA.

Information can be found in the technical data, for example:

ET 200SP AI 2 X U/I 2-, 4-Wire HF

 -> Potential separation

maybe this helps
