Cables for the industrial network ProfiBus-PA and Foundation
BUS 1 * 2 * 0.98 V K-29
Application
Symmetrical twisted pair cables are designed for single stationary installation in industrial automation systems for technological processes and transmission networks in hazardous areas built in acc. PROFIBUS IEC 61158-2 standard and the ISA / SP 50 (Foundation Fieldbus) specifications. Cables are used indoors and outdoors, provided that they are protected from direct exposure of sunlight and precipitation.
