What we offer
Full-Service Support for Industrial Automation
Industrial Automation Co. goes beyond parts sourcing. We provide the technical expertise, repair capabilities, and field support your facility needs to minimize downtime and extend equipment life.
Send-In Repair
Ship your failed drives, PLCs, HMIs, and power supplies to our repair center. Factory-trained technicians diagnose, repair, and load-test each unit before it returns to you.
Sourcing & Procurement
Global sourcing network for discontinued and hard-to-find parts. We locate alternatives, cross-reference equivalents, and help you build critical spare inventories.
Preventive Maintenance
Scheduled inspections, thermal scans, drive and panel health checks, and firmware reviews that catch failing components before they take a line down.
Technical Support
Experienced engineers help with part selection, compatibility questions, troubleshooting guidance, and application support before and after your purchase.
Surplus Buy & Sell
We buy excess and surplus automation inventory and help facilities monetize idle stock while others find cost-effective alternatives to new equipment.
Specialized capabilities
Engineered Solutions, Control Panels & Asset Analytics
When off-the-shelf is not enough, our engineering and service teams deliver custom automation systems, built-to-order control panels, and data-driven lifecycle audits to reduce risk across your operation.
Specialized
Industrial repair & field service
Send us the unit or bring us to the unit. Our engineers repair drives, servo amplifiers, power supplies, control boards, HMIs, encoders, and motors down to the component level — then test them under load on the bench before they go back in the crate.
Evaluation is free, rush turnaround is available, and every repair carries the same 2-year warranty as a new part.
-
Free evaluation
The unit is logged, inspected, and diagnosed. You get a fixed repair quote and a turnaround date before any work starts.
-
Component-level repair
Failed components are replaced, connections reworked, firmware and parameters restored, and wear items refreshed.
-
Load test & burn-in
Every repair runs on the bench under representative load, with results recorded on the repair report you receive.
-
Return, or install on site
Ship it back with a 2-year warranty, or have a field technician reinstall and re-commission it on your equipment.

Services FAQs
Yes. Contact our team for urgent onsite diagnostics and repair. Response times vary by location and technician availability. We serve facilities throughout the Raleigh–Richmond corridor and surrounding metros.
We design and build automation systems ranging from single-machine retrofits to plant-wide motor control — PLC/HMI/SCADA programming, VFD and drive integration, and legacy migrations. Custom UL 508A control panels are fabricated in-house, and every project includes factory acceptance testing and onsite commissioning.
An asset lifecycle audit reviews your installed equipment and spare parts inventory to identify obsolete, end-of-life, and at-risk components. You receive a prioritized report with replacement recommendations so you can plan ahead instead of reacting to unexpected failures.
Our primary onsite coverage is the Raleigh–Richmond corridor and Greater Triangle and Richmond metros. Contact us to discuss service availability for other locations — we may be able to accommodate travel for larger projects or emergency calls.
