  16. Dupline has free Topology Jens Neigaard

  17. Dupline Cables • Single (twisted)pair of wires • Shield not required • Recommended min. cross sections • Long distance: 1.5mm2 • Medium distance:0.8 - 1.0 mm2 • Short distance:0.35 mm2 • Low capacitance for longdistances • (preferably < 80 nF/km) Jens Neigaard

  18. Dupline Installation • Never connect DuplineCommon • to Ground • Treat the Dupline cable as a signal wire • Use DT01 termination unit for • distances > 1.5 km • Check correct wiring during • installation Jens Neigaard

  19. Cable Splicing / Isolation • Use soldering splices • Splices must be water tight • No leakage or connection between wires or • fromwires to ground Jens Neigaard

  20. Rules for Dupline-powered Devices • The total current consumption must not exceed max current output of the channel-generator: • G34900000:Max. 70 mA • G38000015: Max. 130 mA • b) The total current consumption in the network multiplied bythe 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 Ohms • With 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 mA • Max 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.
