Control circuit:
Rated voltage: DC/AC 24 to 230 V (0.85 to 1.1 x Us)
Max. line length (applies to total of current and return conductors):
● AC (line capacity: 300 pF/m):
● DC (min. cross-section 0.75 mm²): 1500 m
Max. connectable cross-section: 2.5 mm²
Fuse: max. 4 A

– 24 V: 5000 m
– 110 V: 800 m
– 230 V: 200 m
The values apply for 50 Hz, at 60 Hz the line lengths must be reduced by 20%.
WARNING
If the permissible cable lengths and/or the permissible cable capacity is exceeded,
then due to the couple capacity of the cable and the associated residual current it
may be the case that the relay remains energized in spite of opened activation
element.
