Tested and graded used Allen-Bradley and Siemens surplus control parts the OEM stopped making — PLCs, HMIs, drives, servo and I/O. Because a stopped line can't wait eight weeks for a redesign.
Rockwell and Siemens retire product lines. Factories don't. Millions of machines still run on controllers you can no longer buy new.
A stopped production line burns thousands per hour. Maintenance managers don't shop on price when the plant is dark — they shop on availability. That's the shelf we keep.
ControlLogix L6x, PanelView Plus 6, PowerFlex 40, SIMATIC S7-300 — all officially retired. The installed base didn't get the memo.
Same catalog number, same firmware family — powered up and function-tested before it ships. Drop it in the rack and run.
The default control platform of American manufacturing. If a US plant was built in the last forty years, odds are it runs on AB — our shelf is built around that reality.
The global standard — and the S7-300, retired in 2023, is now one of the most hunted controllers on earth. We stock it, plus drives, panels and CNC spares.
Every listing ships with photos of the actual unit, function-tested. See a price you don't like? Make an offer — we answer the same day.
Plant closures, MRO surplus and panel-shop pull-outs across the US — bought whole, so rare parts come with the common ones.
Powered up and function-checked: CPUs boot and hold program, HMIs light every pixel, drives run under load.
Graded honestly — sealed surplus, refurbished, or used-working — with photos of the actual unit you'll receive.
Anti-static packed and shipped from New Jersey within 24 hours. Overnight when the line can't wait.
ReMax Electronics is an independent dealer of used and surplus industrial automation, electrical, and MRO components, built on ten years of buying and selling professional equipment across the United States. We buy whole panels, plant surplus and MRO stock, test every unit that comes through the door, and keep the discontinued parts that keep American production lines running — Allen-Bradley first, Siemens alongside.
Every listing is the exact unit you'll receive: function-tested, condition-photographed, anti-static packed, and shipped from New Jersey within 24 hours.
Don't see your part? We source against want-lists daily. Include the full catalog number and series letter — quotes go out the same business day.
ReMax Electronics is an independent surplus dealer, not an authorized distributor of Rockwell Automation / Allen-Bradley, Siemens, or any manufacturer listed here. Units may carry earlier date codes or series letters than factory-current stock, and the original manufacturer's warranty does not apply — every item is covered by our own 30-day functional guarantee instead. On programmable devices, firmware presence, revision level, and your rights to obtain or install firmware are not guaranteed and remain the buyer's responsibility. Read the full surplus product notice.
Independent reseller. ReMax Electronics is an independent dealer of used and surplus industrial automation equipment. We are not an authorized distributor, reseller, or service partner of Rockwell Automation / Allen-Bradley, Siemens AG, or any other manufacturer whose products appear on this site, and nothing here implies any affiliation, sponsorship, or endorsement by them.
Date codes and series. Because our inventory comes from the surplus market, a unit may carry an earlier date code, series letter, or hardware revision than what currently ships from the factory or through authorized channels. Where the series letter matters for your application, ask us before buying — we photograph and confirm the label of the exact unit you will receive.
Warranty. Products sold outside a manufacturer's authorized channel are not covered by the original manufacturer's warranty, and that warranty does not apply to anything sold here. In its place, every unit is backed by ReMax Electronics' own 30-day functional guarantee: if it doesn't work on arrival as described, we replace it or refund it.
Firmware on programmable devices. PLCs, HMIs, drives and similar programmable products may arrive with firmware installed, or they may not — and if firmware is present, it may not be the revision your application needs. We give no assurance about firmware presence or revision level, about your eligibility to download or license firmware from the manufacturer or its distribution network, or about your right to install it on this hardware. We do not source or load firmware on a buyer's behalf. Reviewing and complying with any end-user license agreement connected to firmware is entirely the buyer's responsibility.
Trademarks. All product names, brand names, logos and catalog numbers are the property of their respective owners and appear on this site solely to identify the goods being sold.
