Not directly. 230V expansion modules can only be used on 230V LOGO!s or other 230V expansion modules. 24V expansion modules may only be used with 24V LOGO!s or on analog expansion modules. 24V extension modules can only be used with 230V LOGO!s or 230V extension modules if an analog extension module is placed between the 230V module(s) and the 24 V module(s).

Digital modules have no potential separation. That's the reason why you don't have to mix digital modules with different voltage classes.
