서지 프로텍션

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

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.

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*).

FieldConnex® 서지 프로텍터는 낙뢰나 기타 전압 서지 위험이 높은 공정 플랜트에 쓸 수 있습니다. DIN 레일 설비나 IP67 인클로저용 서지 프로텍터를 써서 필드버스와 모든 장비를 보호할 수 있습니다.
