Total COM loop unit current consumption
Figure 31. Graphs showing the cable length in relation to the COM loop units' total
current consumption. NOTE! The graphs start at "0 mA" and 863 m cable length
respectively but graph 1 ends at "320 mA" and graph 2 ends at "350 mA". End of
graph = max. allowed loop current. (863 m cable length = 42.3 ohm.)
NOTE! The graphs are valid for the cable type ELQYB 2 x 1 mm
(0.75mm
2
) with the conductor resistance 24.5 ohm / km. The total
conductor resistance (ohm) = L conductor (ohm) + C conductor
(ohm).
