NOTICE!
Risk of damaging the PLC modules!
The PLC modules can be damaged by overload.
Make sure that the total current of each output common terminal (R0..3 and
R4..7) does not exceed 8 A.
Never connect total currents > 8 A per group.
If the group fuse protection is not sufficient, then individual fuse protection of the
outputs should be used.
The module provides several diagnosis functions (see Diagnosis Ä Chapter 1.6.1.1.13.6 “Diag-
nosis” on page 264).
The digital inputs can be used as source inputs or as sink inputs.
NOTICE!
Risk of malfunctions in the plant!
A ground fault, e. g. caused by a damaged cable insulation, can bridge switches
accidentally.
Use sink inputs when possible or make sure that, in case of error, there will be
no risks to persons or plant.
