Segment Protectors (Trunk to Spur)

Pepperl+Fuchs' FieldConnex Fieldbus Couplers such as FieldBarriers and Segment Protectors connect instruments to the fieldbus. These fieldbus couplers are mounted in the field near the field device. They come as wiring interfaces with short-circuit protection and power limiting explosion protection.

These couplers protect the trunk from short circuits, as it is possible that short circuits can occur on the spur connection while working on devices. This is why our fieldbus installation technology offers individual protection at each spur. When a short circuit occurs, the current is limited, and the segment remains in operation. When the fault is removed or repaired, the spur automatically resumes operation. This important feature enables the use of fieldbus even in the most demanding environments.

Any explosion protection method is possible (FISCO, Entity, High-Power-Trunk) with Pepperl+Fuchs’ reliable and proven field distribution components. Options exist for practically any connection and any explosion hazardous area.
