Buying 1746-N04I from Flexa Systems
Buy the Allen-Bradley 1746-N04I, an SLC 500 family PLC part that is in stock refurbished and available on request brand new, or send yours to Flexa Systems for repair.

Before ordering, read the catalog number and revision from the label on your installed unit so the replacement lines up with your program and drawings. Each refurbished 1746-N04I is tested before it ships, carries a 2-year warranty and typically costs 30-60% less than a brand new unit.
Repair option: send in your faulty unit for component-level repair — $400.00 with free diagnostics, a 2-year warranty, and a 5–30 business day turnaround. Repair typically costs 40–70% of a new unit, saving you 30–60%. Learn more about our SLC 500 repair and PLC repair service.
