Connecting LOGO! and the digital modules to 230 V
Multi-phase operation
Not observing the following instructions can lead to injury!
The expansion modules DM8 230R and DM16 230R must be operated with the
same type of power supply (DC or AC) as the connected 230V version of the
CAUTION
LOGO! basic module!
The same supply output "+/-" (direct voltage) or "N/L" (alternating voltage) must
be connected to the same phase on both the DM8/16 230R expansion module
and the connected LOGO! basic unit!
The LOGO! 230RCE features 8 digital inputs in two groups.
Within a group, the same phase must be used at all inputs. Different phases are
only possible between the groups!
This means that you use the four inputs [I1-I4] on phase L1 and the four inputs [I5-
I8] on phase L2 according to
The digital module DM16 230R is also divided into two groups.
Digital modules can only be connected to devices with the same voltage class,
here 230V for the LOGO! 230RCE.
