Note
The digital inputs of LOGO! 230RCE/230RC/230RCo and of expansion module DM16 230R
are divided into two groups, each consisting of four inputs. Within the same group, all inputs
must be operated on the same phase. Different phases are only possible between the
groups.
Example: I1 to I4 on phase L1, I5 to I8 on phase L2.
The inputs of the LOGO! DM8 230R must not be connected to different phases.
