Serving Ann arbor, mi Facilities

Automotive and aerospace suppliers around Ann Arbor run production on control platforms that went end of life years ago. The lines are dialed in, qualified, and hard to justify replacing just because a PLC or HMI is no longer supported. The real problem is finding a replacement module or drive quickly enough to keep uptime on track.

PLC Department supports Ann Arbor plants, from Ypsilanti and Saline up through Dexter and Whitmore Lake, with an independent sourcing service built for aging controls. We track down obsolete and hard-to-find Allen‑Bradley, Siemens, Mitsubishi, Omron, Schneider, and GE Fanuc PLCs, HMIs, VFDs, servo drives, and I/O from our US inventory and supply network. You get fast quotes, POs accepted, and a 1‑year warranty on tested surplus and new‑open‑box parts.

For automotive machining, stamping, and assembly operations, a failed legacy processor or communication card can trigger unplanned downtime, scrap, and missed shipments. Many Ann Arbor and Milan area shops still rely on older SLC, PLC‑5, and early CompactLogix hardware, or legacy drives that are no longer supported. Our team understands these installed bases and can often cross to compatible revisions, firmware ranges, and series so your controls engineers can drop the part in and resume production with minimal changes.

In plastics and rubber molding, as well as industrial machinery manufacturing around Adrian, Tecumseh, Chelsea, Dundee, and Michigan Center, keeping legacy injection presses, extruders, and custom machines running is often more practical than a full controls retrofit. We help maintenance and controls teams source older operator interfaces, temperature controllers, and motion components so you can plan upgrades on your own timeline instead of being forced into a rushed project by a single failed board.

From utilities and power generation equipment that cannot go offline easily to OEMs in Vandercook Lake that must support machines in the field, Ann Arbor area teams use PLC Department as a backstop for aging automation. Call (833) 800‑7748 or email your BOM to request a quote, compare options, and keep your existing controls platforms running with less risk.

Frequently Asked Questions

Can you ship PLCs and VFDs to Ann Arbor, MI on our UPS or FedEx account?

Yes. PLC Department ships to Ann Arbor every week and can use your UPS or FedEx account if you prefer. Tell us your carrier and account number when you request a quote, and we will arrange shipping from our Texas based inventory or partner locations.

We still run legacy PLC platforms in Ann Arbor. Can you source discontinued Allen-Bradley and Siemens parts?

Our sourcing team focuses on obsolete and hard-to-find automation hardware. For Ann Arbor facilities we routinely track down discontinued Allen‑Bradley and Siemens PLCs, I/O cards, HMIs, and drives, then provide options, pricing, and lead times so you can avoid a premature controls retrofit.

Do Ann Arbor automotive suppliers need an account to send POs to PLC Department?

You can start with a formal quote and then issue a PO once your internal approval is done. Many Ann Arbor automotive and aerospace suppliers order by PO. We can include your part numbers, terms, and any documentation your purchasing and accounts payable teams require on the quote and invoice.

How does your 1-year warranty work for Ann Arbor buyers using tested surplus parts?

Every tested surplus and new‑open‑box item we sell to Ann Arbor customers is covered by a 1‑year warranty. Parts are inspected and function tested where applicable before shipment. If a covered unit fails under normal use within that period, contact us so we can arrange repair, replacement, or refund.

Can you support outlying areas like Saline, Dundee, and Michigan Center from this Ann Arbor page?

Yes. We regularly ship automation parts to shops and plants in Saline, Dundee, Michigan Center, and other communities near Ann Arbor. The same pricing, warranty, and sourcing help apply, and orders are shipped from our Texas base or partner warehouses to your dock or job site.
