What We Do
IndustrialPLCHub is a curated directory of legacy industrial automation components — PLC processors, I/O modules, power supplies, HMI panels, and drives from manufacturers like Allen-Bradley, Siemens, Modicon, GE Fanuc, and Omron.
We index verified listings from eBay so that plant managers and automation engineers can quickly locate hard-to-find replacement parts without spending hours searching manually.
Why Legacy Parts?
We focus specifically on parts that are no longer in primary distribution but are still critical to facilities that cannot afford a full system migration. Our catalog covers modules from major platforms including ControlLogix, SLC 500, MicroLogix, SIMATIC S7, Modicon 140 series, and more.
How the Catalog Works
- We scan eBay daily for industrial automation listings above a minimum price threshold to filter out low-quality or irrelevant items.
- Each product page includes technical specifications, common failure symptoms, and sourcing context generated for automation professionals.
- All "Check Availability" buttons link directly to eBay search results for that specific part number, so you always see current live inventory.
