ET200s intrensic safe

I have some components located in hazardous zone 0, 1 and 2.
The control panel is located in a safe zone.
Normally you have to use barriers on the signals for the field components.
Siemens now has the ET200Si IO cards. Can i use these without an extra barrier?
Has sombody experience with this?
Thanks a lot.

Hi,
ET200iSP is some thing new for me and have no experience in using it. Since closely related to safety in hazardous areas play caaution and contact Siemens support.
Was going through manual and it does talk about explosion proof enclosures depending upon zone.
Here is the link for manual
