Technical identity of K-250R and the decisions that affect fit
Pepperl+Fuchs K-250R is a precision measuring resistor for converting a 0–20 mA measurement into a 0–5 V signal. The shared product montage is a category reference image rather than a photo of this exact K-250R variant. The table places the verified identity and useful selection data at the front; the notes below explain where a maintenance or purchasing team should confirm the installed circuit.

Application path
In this installation, K-250R supports converting a 0–20 mA measurement into a 0–5 V signal. Start at the field device or mechanical target, follow the signal through the connection and identify what the host expects. A catalog family resemblance cannot establish output polarity, scaling, hazardous-area approval or interchangeability. The complete K-250R code is the procurement reference, while the as-installed drawing is the acceptance reference.
On-site proof
After K-250R is connected, Measure the resistor and compare voltage at representative loop currents. Record the input condition and the controller's observed response at both ends of the useful operating range. Also check supply, diagnostics and any line-fault indication. A successful power-on indication alone does not prove that K-250R has the correct configuration.
Replacement decision
When purchasing K-250R, Specify K-250R precisely; a generic 250 Ω part may not meet the required accuracy. Share the full model, site photos and required certificates with the supplier. Any proposed alternative should be checked against the exact connected equipment and signed off before it replaces K-250R; a similar-looking code is a search reference, not a declared equivalent.
Installation interface
Before fitting K-250R, Verify the control input loading and the effect of a 250 Ω series burden on the current loop. Inspect available cabinet or machine space, cable exit, terminals, environmental limits and nearby equipment. If an old unit has user settings, document them before removal. Confirm the latest nameplate and electrical drawing because K-250R variants can share an enclosure while differing in function.
Other visually related ordering codes
The following designations resemble the K-250R naming pattern and are collected here to help buyers locate variants. Their functions, electrical ratings, connections and approvals may differ. The exact K-250R technical values above must not be copied onto another suffix without checking its own datasheet.
No additional same-pattern designation is listed here for K-250R. Confirm any requested alternative against the manufacturer's full code.
Handover note
Keep the drawing, configured settings, inspection result and purchasing record with K-250R. Recheck the current manufacturer datasheet if the duty, mounting, network or approval changes. This closes the K-250R selection and commissioning review without treating related codes as interchangeable.
Additional visually similar Pepperl+Fuchs model designations
These complete codes are collected for model search and identification because their printed designations look similar. They may represent different products, electrical interfaces, mechanical sizes or approvals. They are not declared interchangeable with K-250R. Verify each complete designation against the manufacturer record and the installed equipment before ordering.
