Kabellänge [m]
Cable length vs true watts applies to DC supply
(minimum supply voltage 24.0 VDC)
The following can be read from the family of curves:
– Cable with conductor 0.75 mm² gives: Cable length 60 m
– Cable with conductor 1.0 mm² gives: Cable length 80 m
– Cable with conductor 1.5 mm² gives: Cable length 115 m
– Cable with conductor 2.5 mm² gives: Cable length 200 m

If the actuators are supplied locally with 24 VAC via a separate transformer, line
lengths can be much increased. Regardless of the power ratings for the actuators
connected, the line lengths will be according to the following table.
