UNITRONIC® BUS PA PROFIBUS-PA in intrinsically safe areas PROFIBUS 100 Ohm +/-20% Application PROFIBUS-PA has been developed especially for process engineering (process automation) to connect sensors and actuators - even in hazardous areas with risk of explosion - with one common bus cable (data communication and power supply of devices). PROFIBUS® PA is standardized in EN 50170 like PROFIBUS® DP and PROFIBUS® FMS. Note Transmission technology in accordance with international standard IEC 1158-2. Bitrate = 31.25 kBit/s. Characteristic impedance at 31.25 kHz = 100 Ohm ±20% (at 31,25 kHz). Maximum segment length depends on several factors (e.g. supply voltage, current demand). Please see assembly guide of system manufacturer. PROFIBUS (according to DIN 19245 and EN 50170 z.B. for SIEMENS SIMATIC NET). LAPP KABEL is member of the PROFIBUS Nutzerorganisation (PNO), i.e. PROFIBUS user organisation. SIMATIC = registered trademark of SIEMENS AG. PA = Process Automation.
