Buying 6AU1400-2PA23-0AA0 from Flexa Systems
Buy the Siemens 6AU1400-2PA23-0AA0 PLC brand new and in stock, with refurbished units available on request, or send yours to Flexa Systems for repair. This controller runs the machine logic, so an exact replacement lets you restore the line by loading your existing program instead of re-engineering the control system. Read the full order number from the label on your installed unit and compare it character for character with 6AU1400-2PA23-0AA0, because a near-identical number may not be a drop-in substitute. Each unit is tested before it ships and carries a 2-year warranty, and a refurbished controller typically saves 30-60% compared with new.
Repair option: component-level repair is available for this model — 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%. Request a repair quote. Learn more about our Siemens repair and PLC repair service.
