Technical identity, constraints and acceptance of DB-LBF-I1
Pepperl+Fuchs DB-LBF-I1 is a fieldbus surge protector base used to carry a plug-in fieldbus surge module on a DIN rail. This entry identifies the complete DB-LBF-I1 designation and shows the technical data that can be used as a starting point. The shared main image is a Pepperl+Fuchs category reference montage, not an exact photograph of DB-LBF-I1. Final selection still requires the fitted label, the latest manufacturer record and the actual site drawing.

Decision memo
The job of DB-LBF-I1 is to carry a plug-in fieldbus surge module on a DIN rail. Define its boundary in the real installation: what connects upstream, what response is required downstream, how it is powered and how it is mounted. A model that looks like DB-LBF-I1 may not provide the same circuitry or approvals. Capture the present configuration before removal, including any addresses, calibration, scaling, taught limits or software settings.
Match the installed assembly
For a replacement DB-LBF-I1, compare the full printed code character by character. Confirm supply, I/O direction, signal type, terminal or plug pinout, operating environment and mechanical clearances. If the circuit has functional-safety or hazardous-area requirements, obtain the exact approval documents for DB-LBF-I1; the visual similarity of another code is not a valid substitute. Include mating heads, reflectors, boards, cables and licences as separate line items where needed.
Prove the function
At commissioning, Verify trunk continuity, grounding and the matched DP-LBF module. Test DB-LBF-I1 in the assembled system using a known input or mechanical condition, then read the corresponding output and controller response. Repeat at the low and high ends of the real operating window. A status LED alone cannot prove that DB-LBF-I1 has the correct settings, connected accessory or alarm action. Keep the measured values and any deviations in the maintenance record.
Send a complete enquiry
An RFQ for DB-LBF-I1 should quote the complete designation, required quantity, installed controller or host, connection style, certification need and the intended operating environment. Request confirmation for any alternate suffix. Related-looking models are indexed below to help identify inventory, but technical table values on this page apply only to the named DB-LBF-I1 variant where verified. Each other complete code needs its own specification review.
Related-looking model strings
These designations visually resemble DB-LBF-I1; they can still have different functions, ratings, interfaces and approvals. Verify each complete code independently before ordering or substitution.
No additional same-pattern code is grouped with DB-LBF-I1 here; any alternative requires its own review.
Close-out
After the handover of DB-LBF-I1, archive the exact label, configuration backup, drawings and test result. If the process or host changes later, redo the relevant match and acceptance checks for DB-LBF-I1. Do not treat the product montage or the related-code index as a wiring diagram or a declaration of interchangeability.
