Function: R-SP-E12

The R SP E12 Segment Protector is a device coupler that connects field instruments to the segment.

Flameproof (Ex d) field devices are connected to the trunk line via one output each. Trunk and spurs are certified increased safety (Ex e).

Short-circuit protection ensures proper operation of the segment in case of unwanted faults at the spur. Work on devices always requires a hot work permit. The integrated fieldbus terminator features high-availability design and is selectable.

Connectors are fixed screw terminals. Any grounding and shielding concept is possible based on FieldConnex enclosure solutions.

Customizable housings host one or more Segment Protectors for different output counts.
