Function
The R-SP-E12 Segment Protector is a fieldbus coupler that
connects instruments to the fieldbus 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.
