Thank you for your answer.

You can’t directly put a 24V extension module after a 230V LOGO!, but there is a solution:

You place an analogue module between LOGO! 230V and the 24V module(s).

Hallo alles-logo,

That is true, and is even recommended by the manufacturer if the PV input of a controller is used (see manual),

but who buys an expensive module if they don't use it ?

Especially since they then have to accept losses in the fast communication of the downstream digital modules.

OK, but if an application needs 230V and 24V I assume using an extra analogue module is cheaper than buying two LOGO!s.

And with two LOGO!s you need to program two user programs. It least I would prefer the solution with only one LOGO!.
