Compare condition, included accessories, destination shipping, taxes and seller terms before comparing total cost. No currency conversion or invented market price is applied.
Verify the connected load cells are analog strain-gauge full bridges within the documented 1–4 mV/V interface range; confirm calibration data can be restored.
Match the installation mode (S7-1200 or standalone), RS485/Ethernet wiring and required 4 DI / 4 DQ / 1 AQ. Obtain the actual firmware revision before replacement.
For legal-for-trade weighing, confirm the required local approval and verification for this WP251 installation; an exact part number alone does not preserve certification.
For fitment help, give the seller your exact equipment model, existing part label, revision and connector photos. Ask for written confirmation before ordering. Do not share confidential machine data publicly.
Shipping scope and return or warranty terms above are specific to each reviewed offer. “Unknown” means the destination or term was not established. Confirm delivery to your postcode, landed cost and the seller’s return conditions before payment.
