Target Application:

Foundation Fieldbus is the dominant industrial network in the oil,gas and petrochemical industries as well as most process industries. Fieldbus is an all-digital,serial,two way communications protocol that standardizes the interconnection of field devices at a communications rate of 31.25 kB/s. The Field devices are accessible communication netowrks(running at 1 or 2.5Mb/s), through linking devices. These cables have electron beam(E-Beam) XLPE insulation that offers lower capacitance, longer run lengths and improved cut through and chemical resistance compared to other insulations. These cables are fire resistant as per IEC-60331-23 for 750 deg C for 90 minutes. Type A, H1 registered cable.

Le nostre tecnologie

PROFIBUS è un sistema di comunicazione digitale standardizzato ed aperto, utilizzabile in tutte le aree di applicazione, dal manifatturiero al processo.

PROFINET è l'innovativo standard aperto per l'Industrial Ethernet. E' in grado di soddisfare tutti i requisiti necessari per le applicazioni di automazione industriale.

IO-LINK è la prima tecnologia IO standardizzata a livello mondiale (IEC 61131-9) per comunicare con sensori ed attuatori sotto il livello di comunicazione del bus di campo. Può essere integrata con PROFIBUS e PROFINET.
