Rules for Dupline-powered Rules for Dupline-powered DevicesDevices
a) The total current consumption must not exceed max current output of the channel-generator:G34900000: Max. 70 mAG38000015: Max. 130 mA
b) The total current consumption in the network multiplied by the cable loop resistance must not exceed 2 V
An example: 2 km 1.0 sq.mm twisted pair is used. G50101106 is used both with input and LED
The resistance of a 1.0 sq.mm. core is app. 20 Ohms/km. With a wire length of 2 km the resistance per wire is 40 OhmsWith the 2 Dupline wires the total resistance is 2 x 40 ohms = 80 Ohms.This means that the max total current is 2 V / 80 Ohms = 25 mA.One G50101106 with LED function uses 1.2 mAMax Number of G50101106 = 25 mA / 1.2 mA = 20 units
If the LED is not used the current per G50101106 is only 0.15 mA so in this case the result is:
Max number of G50101106's = 25 mA / 0.15 mA = 166 units.
