Downloads

 

The Intrinsically Safe technology incorporated in the DF 47-17 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 DF47-17 are completely independent of each other.

  • H1 Isolated Barrier and I.S. Power Supply in accordance with the FISCO Model;
  • H1 Fieldbus Signal Repeater;
  • Conform to the IEC 1158-2, 31.25 kbits/s standard for Fieldbus. (FOUNDATION fieldbus and PROFIBUS PA);
  • IEC, FM & CENELEC Intrinsic Safety standards certified;
  • In Compliance with IEC 60079-27, FISCO and FNICO Power Supply;
  • Dual Marking according IEC 60079-11 and IEC 60079-27;
  • Bus termination on hazardous area.
