Note
LOGO! 230RCE/230RCEo and expansion module DM16 230R each contains
two groups of
four inputs, for a total of eight. Within
each group, you must operate all inputs 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
.
You must not
connect the inputs of the LOGO! DM8 230R to different phases.
Sensor connections
Connecting glow lamps and two-wire proximity switches (Bero) to LOGO! 230RCE/230RCEo
or LOGO! DM8 230R (AC) and LOGO! DM16 230R (AC)
The figure below shows how you connect a switch with a glow lamp to LOGO!. The current
that flows through the glow lamp allows LOGO! to detect a "1" signal even though the switch
contact is not closed. If, however you use a switch that has the glow lamp fitted with a power
supply, this response does not occur.
