Sell Surplus Automation and Control Parts

Idle PLCs, drives, HMIs, and I/O carry surprising value because plants running legacy control systems need in-kind replacements the OEMs have discontinued. A sealed obsolete module can be worth far more than its original list. We buy current-series and legacy parts, new-surplus and used, single pieces or full pallets.

What affects your offer

Condition tier: factory-sealed new-surplus commands the top offer; new-open-box and tested-used are next.

Current-series vs. obsolete: obsolete-but-in-service lines (SLC 500, PLC-5) can outprice current parts as supply dries up.

Exact part number and series/firmware revision determine compatibility, and therefore value.

Quantity and consistency: matched lots of the same part number are worth more per unit than mixed singles.

Brand demand: Allen-Bradley, Siemens, Fanuc, and top vision brands move fastest.

Original packaging, labels, and any calibration or date-of-manufacture data.

Common questions

What to send

  • The exact catalog/part number plus series and firmware revision from the label.
  • Condition: sealed, new-open-box, tested-working, or untested/unknown.
  • Clear photos of the product label/nameplate and the packaging.
  • Quantities per part number, and note if items are a matched lot from one system.
