Description
UNITRONIC® BUS PB FD PHalogenfree, highly flexible PROFIBUS cableBus cable for PROFIBUS-DP, -FMS and FIP. Halogen free and enhanced flame retardance. Temperature range from -40°C bis +80°CPower chainDue double screening it is suitable for installation in electromagnetically demanding areasCables can be used for PROFIBUS-DP as well as PROFIBUS-FMS and FIPFor use where the combination of a halogen-free outer sheath with properties similar to PUR and enhanced flame-retardance is requiredApplication rangePROFIBUS DP (in accordance with DIN 19245 and EN 50170, e.g. for SIEMENS SIMATIC® NET, also suitable for FIP -Factory Instrumentation Protocol).For highly flexible applications (power chains, moving machine parts)Suitable for torsional applications which are typical for the loop in wind turbine generators (WTG)Halogen-freeFlame-retardant according IEC 60332-1-2Oil-resistantBased on the bit rates listed, in accordance with PNO specifications the following maximum cable lengths for a bus segment apply (cable type A, PROFIBUS-DP):93.75 kbit/s = 1200 m187.5 kbit/s = 1000 m500 kbit/s = 400 m1.5 Mbit/s = 200 m12.0 Mbit/s = 100 mStranded bare copper wireCore insulation: foam skin, (O2YS)Overall screening with copper braid and plastic-laminated aluminium foilOuter sheath: PUR, violet (RAL 4001)Mutual capacitance: (800 Hz): max. 30 nF/kmPeak operating voltage: (not for power applications) 250 VTorsion movement in WTG (wind turbine generator): TW-0 & TW-2, refer to Appendix T0Minimum bending radius: 65 mmTest voltage: Core/core: 1500 V rmsCharacteristic impedance: 150 ± 15 OhmTemperature range: Flexing: -30°C to +70°CFixed installation: -40°C to +80°C
