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.
