Description

I’m selling used Siemens SIMATIC S7-300 PLC CPU modules. I have multiple units available in good condition with normal industrial usage signs — light surface wear and some marks from mounting, but fully intact housings and connectors. The modules include the standard RS232/PROFIBUS and MPI ports depending on the variant, and the front memory/slot covers are present. I have tested basic power-up on several units and they initialise; no physical damage or cracked plastic observed. Ideal for spare parts or refurbishing existing S7-300 systems.
