Segment Protectors are fieldbus couplers for connection of 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.

The R2 series of Segment Protector features innovative design for superior availability:
  • Easy connection of multiple Segment Protectors via T-Connector
  • Incorrect termination is prevented by design, since the terminator can be placed only on the T-Connector of the last Segment Protector
  • Durable installation due to connectors with retaining screws
  • Test points allow the connection of diagnostic tools such as the Mobile Advanced Diagnostic Module without disturbing the wiring
  • High-availability termination
  • Ex ic and Ex nL energy limitation

Segment Protector R2-SP-IC* features the same mechanical design as the R2-SP-N* with added features for superior availability:

  • Progressive fault detection and isolation of infrequent but typical fieldbus faults, e.g. contact bounce
  • Jabber protection handling device defects
  • Ex ic energy limitation

The Segment Protector R2-SP-IC* communicates status from the diagnostic-enabled enclosure leakage sensor and surge protector to the Advanced Diagnostic Module. This communication does not interfere with normal process communication and requires no addressing, configuration or bandwidth on the bus.

Segment Protector F2-SP-IC* offers all the intelligent features for fault detection and protection of the R2-SP-IC*. It is installed in our most compact aluminum enclosure (F2-SP-IC*) with:

  • Quick and convenient local diagnostics: LEDs visible from the outside
  • 4, 6, 8, 10 spurs selectable
  • Cable glands or connector plugs (M12) selectable
  • Optional spring terminals

The Modular Segment Protector simply clips onto the DIN-Rail. Two modules, the trunk module and the expansion module, enable the following features:

  • Smallest footprint in the cabinet per device
  • Easy expandability on the DIN-Rail via Power Rail
  • Ex nL energy limitation
