Used Siemens Industrial Automation Equipment

With over 650 listings, Siemens is by far our largest inventory category. What’s in stock spans the full SIMATIC S7 lineup — S7-300, S7-1200, and S7-1500 processors and CPUs — alongside I/O modules, HMI touch panels, SINAMICS drives, servo amplifiers, SIRIUS contactors and motor protection devices, and DIN-rail power supplies, plus a steady stream of individual replacement parts pulled from decommissioned lines.

We’re an independent surplus reseller, not Siemens AG or an authorized distributor. Every listing is used, surplus, or refurbished, and we describe the actual condition of that specific unit on its product page rather than letting the part family speak for it.

One thing worth knowing before you order: Siemens reuses similar-looking part numbers across firmware revisions, hardware versions, and regional variants. Match the full order number — letter suffixes included — against what’s currently installed, not just the base model. Can’t find the exact Siemens part you need in the list below? Get in touch and we’ll check what we can source.
