Series 9411/21

  • Connection of up to 4 intrinsically safe FISCO field devices to the high power trunk
  • Isolation between intrinsically safe field devices and non-intrinsically safe fieldbus
  • Short-circuit protection for each spur
  • Reduced starting and low short-circuit current through power management
  • LED indication of status and faults on each spur
  • Switchable fieldbus-termination on board
  • Screw terminals, detachable screw terminals (Ex i Spurs) or spring cage terminals

The Ex i Field Device Couplers connect up to 4 intrinsically safe FOUNDATIONTM fieldbus H1 or Profibus PA field devices to a non-intrinsically safe fieldbus (high power trunk). The intrinsically safe spurs comply with FISCO specifications and are electrically isolated from the trunk. The Field Device Couplers feature a power management to minimize current from the trunk.

The couplers are mounted on DIN rail or directly in enclosures made of glass fibre reinforced polyester or stainless steel. The cable shields can be connected to earth capacitively at the terminals or directly at the cable screen bus bar. An IP30 cover protects the non-intrinsically safe connections of the trunk so that work can be carried out at any time on the intrinsically safe spurs and field devices.
