PLC Controllers — Brand New, Refurbished & Repair, All Brands

About PLC & Industrial PC Systems

Programmable logic controllers (PLCs) are the decision-making core of industrial automation — reading sensor inputs, executing control logic, and driving outputs on production lines, packaging machines, and process systems. Flexa Systems stocks and repairs PLC processors, I/O modules, power supplies, and communication modules from Allen-Bradley (ControlLogix, CompactLogix, SLC 500, MicroLogix), Siemens SIMATIC S7, Omron, Mitsubishi, and other major manufacturers, alongside industrial PCs and panel PCs.

PLC Repair & Parts Service

When a PLC processor or I/O module fails, component-level repair or a refurbished replacement from stock is the fastest path back to production — especially for discontinued families like SLC 500 or S7-300 where OEM replacements are no longer made. Our service engineers repair power supply sections, communication ports, backplane interfaces, and I/O circuits at circuit board level, saving 30–60% vs. new. Refurbished units cost 40–70% of new. All repairs and units carry a 2-year warranty.
