Segment Protectors are fieldbus couplers for connecting instruments to the fieldbus segment. They provide short-circuit protection to the trunk line. This is important where hot work performed on a field instrument would cause the entire segment to fail through unintended short circuits to the spur line.
For hazardous areas main line Segment Protectors (R2-SP* and F2-SP*) can be installed in Zone 2 / Div. 2. Some Segment Protectors are certified for Zone 1 installation. Spurs are installed with ignition protection method:
- Increased safety for instruments in Zone 1/Div. 1
- Intrinsic safety Ex ic for instruments in Zone 2/Div. 2
Segment Protectors for DIN-Rail installation are available with pre-engineered enclosures in GRP or stainless steel housings. The spur count can be up to 24 and accessories are selectable for easy installation. The housing is delivered installation ready with all internal wiring prepared. All components are covered with a single certificate for explosion hazardous areas when needed. Please note our extremely compact and robust Segment Protectors in aluminum housing.
