Industrial Automation Parts Supplier Serving Longview, WA

It is common in Longview paper, pulp, and wood products mills to see relay panels still tied into PLC-5, SLC 500, and newer Ethernet/IP architectures on the same line. Keeping that mix running takes more than a catalog order. You need a supplier that understands how to hunt down an obsolete power supply for one system while also stocking spares for your current CompactLogix or Siemens hardware.

PLC Department supports Longview maintenance and engineering teams that are trying to keep older process lines productive while newer assets come online. For paper machines, chemical dosing skids, and finishing lines, we source PLCs, HMIs, VFDs, servo drives, and I/O from brands like Allen‑Bradley, Siemens, Mitsubishi, Omron, Schneider, and GE Fanuc. Tested surplus and new open box units ship from our Texas based inventory and partner network, with a 1 year warranty on qualifying items so you can put critical spares into service with confidence.

Food processing and packaging facilities around Longview face the same mixed fleet challenge. A filler might still be running on a legacy GE Fanuc platform, while downstream packaging has newer Ethernet capable motion. Our sourcing team tracks down discontinued CPUs, older operator panels, and special communication modules, then pairs them with the current generation drives and safety components you need on your upgrade projects. We work with system integrators and controls engineering firms across Cowlitz County who want a single point of contact that can quote the entire BOM, including the hard to find pieces, instead of splitting the job across multiple vendors.

From Kelso and Woodland to Lexington, Longview Heights, St. Helens, and La Center, buyers use PLC Department as an extension of their own procurement group. Email a parts list or specific SKU, or call (833) 800-7748 for quick pricing on everything from a single obsolete input card to a full panel build bill of materials. We accept POs, provide formal quotes for project approval, and help maintenance managers keep shelves stocked for both legacy and current controls so Longview operations can focus on production, not parts hunting.
