The Intrinsically Safe technology incorporated in the DF47-12 totally isolates the control network on the hazardous side of the barrier. The I.S. values of the power supply are designed for Fieldbus devices, witches are in accordance with the FISCO model.
The incorporation of a Fieldbus repeater in accordance with IEC 1158-2, 31.25 kbits/s essentially clean and boost the incoming communication signal transmitting it to hazardous environment. The networks of the hazardous and safe sides of the DF47-12 are completely independent of each other.
