Segment Protector R2-SP-IC*

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.
