What the model is used for

Universal transmitter supply with 0/4–20 mA output, two relay contacts, programmable high/low alarm, linearization, and LFD. These features make the unit useful for transmitter loops, analog input panels, alarm trips, and retrofit cabinets. Start by comparing the installed loop with the official product data, then retain the exact suffix in the project record.

Selection checkpoints

Confirm the signal type, supply range, terminal arrangement, and expected output before ordering. Also record the field device or receiving card. A matching housing alone does not establish compatibility.

A useful RFQ list

• Complete Pepperl+Fuchs model and article number
• Application tag and existing drawing revision
• Required quantity, destination, and delivery date
• Certificates, manuals, or traceability documents needed for the site

Commissioning notes

Keep the approved wiring diagram with the replacement record. During testing, verify normal operation, fault behavior, and the indication at the receiving system. Document any configuration switch or setpoint change before the cabinet is returned to service.

Why exact suffixes matter

Nearby K-System or sensor variants may share a mechanical format while using another signal, output, or approval. Ask the supplier to repeat the exact model in the quotation and compare any alternative with engineering before purchase.

Keep the record usable

A model page should help the next person make the same decision. Save the nameplate, the drawing revision, and the selected technical reference together. If the equipment duty changes later, reopen the comparison rather than assuming that the existing spare remains suitable.
