The inputs of these units are groupedinto 2 blocks with 4 inputs each.Different phases are only possiblebetween the blocks, and not within theblocks.

LOGO! 230 ... LOGO! 12/24 ...

For LOGO! to detect a 0 or 1switching status, the switchingstatus must be present for at

least one program cycle.

The inputs of these units are non-isolated and thus require the samereference potential (ground) as thepower supply.
