Description

Pepperl+Fuchs TPH-LBF-IA1.36.DE.1 is a FieldConnex pluggable surge protector for trunk installation on a fieldbus power hub. It protects FOUNDATION Fieldbus H1 and PROFIBUS PA infrastructure against surge voltages and secondary lightning effects while providing diagnostic status indication. The module is rated for 36 V and 600 mA, has a maximum continuous voltage of 33 V and uses direct shield grounding. The diagnostic version consumes up to 6 mA and provides a green flashing LED for normal status and a red flashing LED when maintenance is required.

Overview Manuals Product Applications Compatibility Lifecycle & Replacement

Features:

  • Pluggable Power Hub trunk surge protector
  • 36 V rated voltage and 600 mA rated current
  • Diagnostic LED for status and maintenance
  • FOUNDATION Fieldbus H1 and PROFIBUS PA support
  • Intrinsically safe hazardous-area approvals

Pepperl+Fuchs TPH-LBF-IA1.36.DE.1 is a FieldConnex diagnostic surge protector designed for installation between a fieldbus Power Hub and its trunk cable. It limits surge voltages and secondary lightning effects while supporting FOUNDATION Fieldbus H1 and PROFIBUS PA communication.


The module is rated for 36 V and 600 mA, accepts up to 33 V continuous voltage and provides direct shield grounding. Its diagnostic circuit flashes green for normal status and red when maintenance is required, allowing segment condition to be checked without changing the protected fieldbus function.


TPH-LBF-IA1.36.DE.1 Pepperl+Fuchs: Verify Power Hub compatibility, grounding, hazardous-area approval, trunk wiring and diagnostic status before commissioning.

  • Power Hub trunk surge protection
  • FOUNDATION Fieldbus H1 segment protection
  • PROFIBUS PA fieldbus protection
  • Hazardous-area fieldbus installations
  • Lightning protection zone coordination

TPH-LBF-IA1.36.DE.1 is applied where a FieldConnex Power Hub trunk requires surge protection, direct shield grounding and diagnostic status indication. Its approvals and electrical limits must match the fieldbus segment, enclosure and hazardous-area design.

TPH-LBF-IA1.36.DE.1 is intended for Pepperl+Fuchs FieldConnex Power Hub trunk connections using FOUNDATION Fieldbus H1 or PROFIBUS PA physical-layer technology. Confirm the Power Hub version, segment voltage, current, grounding method and enclosure before installation.


Do not use this diagnostic surge protector with the DART Power Hub Backplane MBHD-FB-D*. A replacement must preserve direct shield grounding, hazardous-area certification, terminal arrangement and the diagnostic interface specified for the installed segment.

Confirm the current Pepperl+Fuchs lifecycle status and availability for TPH-LBF-IA1.36.DE.1 before planning a new installation or replacement. Maintain the exact suffix, approval markings and FieldConnex Power Hub compatibility in controlled maintenance records.


Before replacement, isolate the segment according to the approved procedure and document wiring, shield grounding and LED diagnostic status. Surge protectors are not field-repairable; replace a damaged unit with an approved equivalent and repeat the grounding, insulation and communication checks.
