Flame Retardant Profibus DP IEC 61158 / EN 50170 SINEC L2(Siemens Profibus)
APPLICATION
Profibus DP cables are designed for field networks requiring fast, cyclic data exchange between
controllers and field devices. This cable is usually referred as siemens profibus. This Profibus
modification optimized with respect to velocity and low installation cost, Profibus DP is used as a
replacement for conventional parallel data transmission with 24 V or 0 - 20 mA. With special design
for the outer jacket, the cables are flexible and are suitable for operation at high temperature,
protecting this cables from premature aging, while LSZH properties assure low smoke and corrosive
gas in the event of a fire.
