Registered Product Information

Manufacturer: R. Stahl GmbH
Product Name: 9410/34 (Zone 2 Ex n)
Product Description: FOUNDATION Device Coupler (FDC)
Category: H1 Couplers
Profile: FOUNDATION Device Coupler
More Information:   The Zone 2 Ex n Field Device Couplers connect 4, 8 or 12 explosion protected ic/nL/nA FOUNDATIONTM fieldbus H1 field devices to a non-intrinsically safe / Nonincendive fieldbus (high power trunk). A feedback effect from the spurs on the trunk is prevented in the case of short-circuits by current limiting (spur protection). The Field Device Couplers feature a power management to minimize current from the trunk: * during start-up of a fieldbus segment, the Softstart function activates the spurs one after the other resulting in a significant lower inrush current * in the event of multiple short circuits, all short circuited spurs are de-energized until the failure is eliminated. Even with multiple short circuits per coupler, the trunk is loaded with max. one short circuit current at a time. The couplers are mounted on DIN rail in housings made of fiber glass-reinforced polyester, sheet steel or stainless steel. The cable shields are internally looped through.   Highlights: - Installation in hazardous locations Zone 2 - Connection of up to 4, 8 or 12 explosion protected (Ex ic / nL / nA) field devices to a high power trunk - Short-circuit protection for each spur - Reduced inrush current and low short-circuit current through power management - LED indication of faults on each individual spur - External terminator available - Detachable screw terminals with locking screws - Customer specific enclosures available in different versions - Certified ATEX, IECEx
