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:
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 manual and 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 locally, 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.
Questo tipo di limitatore di sovratensione non prevede cablaggi aggiuntivi. I limitatori di sovratensione possono essere adattati alla maggior parte di installazioni su bus di campo con i FieldConnex® Segment Protectors, ad es. di tipo R2-SP*).
