Application: Legacy compact PLC used in small machine control, OEM equipment and process skids; now discontinued but still widely supported via refurbished parts.
Used; powered and verified for basic operation (RUN status and I/O indicators) before removal.
Housing shows heavy discoloration, scratches, dust and handwritten panel notes from long‑term cabinet use; see photos for cosmetic condition.
Interior components (relays, PCB, capacitors) appear intact with no obvious damage or burns.
Battery age is unknown and should be replaced by the buyer before critical use.
No original box, manuals, or accessories included; listing is for the PLC unit only.
Programming requires an Omron S6‑compatible handheld console or PC interface according to the S6 manuals; these are not included.
Device has been out of production for many years; ideal as a spare for maintaining existing legacy systems where a full control system upgrade is not yet feasible.
Wiring must follow the diagrams in the SYSMAC S6 user’s manual, especially for input commons, output contacts and protective earth.
Buyers should confirm that 3G2S6‑CPU15 matches the exact model used in their machine (voltage, I/O count) before ordering.
