You can connect analog and communication modules to devices of any voltage class. Regards, Marcjan

In your case on a LOGO! 230 you can not connect a LOGO! 24V EM. There is one exception: After an analog EM you can connect a "low voltage EM", like a DM8 24R In your case: 1. 230V LOGO! BM 2. A analog EM (AM2, AM2RTD or AM2 QA) 3. Then the 24V DM Hope this helps
