PROFIBUS PA

Please note that due to site maintenance, not all functionalities of the Pepperl+Fuchs website will be available. Thank you for your understanding.

FieldConnex® Surge Protectors are available for process plants at high risk for lightning strikes or other voltage surges. The fieldbus and all instrumentation can be protected with surge protectors:

  • For DIN rail installation inside control room cabinets or field junction boxes
  • Snap-on connection to trunks or spurs in the fieldbus junction box or control room cabinet
  • IP67 enclosure for field installation

Integrated diagnostics - Zero maintenance

Segment Protector with surge protectors. Integrated diagnostics indicate end of useful life in the control room eliminating routine maintenance checks.

Depending on intensity and frequency of lightning strikes, surge protectors may lose functionality after one or several hundred voltage spikes. Certainly after each lightning strike and at least annually,  surge protector functionality requires validation. Validation is often a labor-intensive process. This work can be eliminated entirely with FieldConnex® Surge Protectors.

FieldConnex® Surge Protectors are available with optional integrated diagnostics. They indicate the end of their useful life via Advanced Diagnostics. A message in the control room indicates the affected spur. The LED of the surge protector indicates which module requires replacement.

Additional engineering for implementation is not required where fieldbus is equipped with the Advanced Diagnostic Module and diagnostic-enabled Segment Protectors.


Convenient installation even as a retrofit

An additional wiring level is omitted with this type of surge protector. The surge protectors can be retrofitted to most fieldbus installations with FieldConnex® Segment Protectors, e.g. Type R2-SP*).
