1 Zone 2 Field Device Coupler 8 purs eries 9411/24 > Connection of up to 8 intrinsically safe FCO field devices to the high power > solation between intrinsically safe field devices and nonintrinsically safe fieldbus > hortcircuit protection for each spur > Reduced starting and low shortcircuit current through power management > LED indication of status and faults on each spur > witchable fieldbustermination on board > crew terminals or detachable screw terminals ( purs) eries 9411/ E00 The Zone 2 Field Device Couplers are installed in Zone 2 and connect up to 8 intrinsically safe FOUNDATON TM fieldbus H1 or Profibus PA field devices in Zone 1 to a nonintrinsically safe fieldbus (high power ). The intrinsically safe spurs comply with FCO specifications and are electrically isolated from the. The Field Device Couplers feature a power management to minimize current from the. The couplers are mounted on DN 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 (optional).
