Control circuit:
Rated voltage: 24 VDC to 230 VAC (0.85 ... 1.1 x Us)
Max. line length (applies to the sum of the outgoing and return lines):
● AC (line capacity: 300 pF/m):
– 24 V: 5000 m
– 110 V: 800 m
– 230 V: 200 m
● DC (min. cross-section 0.75 mm²): 1500 m
36
The values apply for 50 Hz, at 60 Hz the line lengths must be reduced by 20%.
WARNING
Danger to life as a result of exceeding the permissible cable lengths and/or the
permissible cable capacitances
When the permissible cable lengths and/or the permissible cable capacitances are
exceeded, the relay can remain energized as a result of the coupling capacitances of
the cable and the associated residual current, in spite of the fact that the actuating
elements are open. Death and serious injury can result in the event of an error.
• Do not exceed the maximum permissible cable lengths and cable capacitances.
