Green color with no comments reflect full functional equivalent of M340 module for Compact module.
Green color with comment reflect full functional equivalent with differences notes. Check with your application.
Orange color indicates that inputs most cases the M340 module completely replaces the Compact module but differences are noted. For example maxi current per point. Check with your
application.
Red color indicates that there are no direct replacements but there are workarounds. Please consult Schneider Electric for assistance.
