Industrial Automation Parts Supplier Serving Murfreesboro, TN

Many Murfreesboro production lines still rely on aging control systems that quietly run every shift. The problem comes when an original Allen‑Bradley, Siemens, or Mitsubishi PLC card fails and the OEM has ended support. That risk is real for local automotive and transportation equipment manufacturers that still have legacy platforms tied into custom machinery.

PLC Department supports Murfreesboro facilities facing those obsolescence headaches. From our Texas base, we source tested surplus and new open box PLCs, HMIs, VFDs, servo drives, and I/O modules from a nationwide network, then ship directly to your plant. System integrators and controls engineers in automotive and aerospace work with us when they need specific series, firmware revisions, or old communication modules that are no longer offered through normal channels.

Warehousing and distribution centers around Murfreesboro also run a mix of old and new controls. Conveyor systems, sorters, and palletizers may still depend on legacy Omron or GE Fanuc hardware that is woven into your WMS and plant network. We help maintenance teams keep those systems running by tracking down obsolete CPUs, power supplies, and operator interfaces before a failure takes a critical sorter offline.

Food processing and packaging operations from Christiana to Shelbyville often cannot justify a full controls overhaul on a machine that still runs well. Instead, they rely on us to find spare VFDs, safety relays, and HMI panels that match existing panels and recipes. Our sourcing team focuses on the exact catalog numbers you provide so replacements drop in with minimal reprogramming or panel changes.

We also regularly ship to plastics and rubber processors in Manchester and machine shops near Smithville that need specific automation parts fast. Send a BOM or photo of the nameplate, and we will quote available surplus or new open box options with a 1 year warranty. PLC Department accepts POs, provides formal quotes for your purchasing process, and can be reached at (833) 800-7748 when your Murfreesboro line is down and you need hard to find controls hardware located quickly.
