Siemens 6ES7390-1AE80-0AA0 DIN Mounting Rail 480mm – SIMATIC S7-300 Series
Imagine a production line brought to a standstill — not because of a failed PLC CPU or a blown I/O module, but because the structural backbone holding the entire control cabinet together has failed. The mounting rail is the silent foundation of every SIMATIC S7-300 installation. Without a properly rated, dimensionally accurate rail, modules cannot be seated correctly, grounding integrity is compromised, and the entire automation system becomes unreliable. The Siemens 6ES7390-1AE80-0AA0 eliminates this risk by providing a certified, precision-engineered 480mm DIN rail purpose-built for S7-300 system assemblies.
Within the SIMATIC S7-300 mounting rail family, the 6ES7390-1AE80-0AA0 occupies the mid-range length position at 480mm — long enough to accommodate a full-featured S7-300 rack with CPU, power supply, and multiple I/O modules, yet compact enough for space-constrained control cabinets. As part of Siemens’ globally dominant SIMATIC S7-300 platform — one of the most widely deployed modular PLCs in discrete manufacturing, process automation, and infrastructure projects worldwide — this rail is a standard BOM component trusted by system integrators and OEMs across more than 100 countries.

Frequently Asked Questions
- Q: Is the 6ES7390-1AE80-0AA0 compatible with SIMATIC S7-400 modules?
- A: No. This rail is specifically designed for the S7-300 module form factor. S7-400 systems use a different, wider rack system (e.g., 6ES7400-series racks).
- Q: Can I cut the 480mm rail to a shorter length?
- A: Siemens does not recommend cutting OEM rails, as this may compromise the grounding bus integrity and module alignment. Siemens offers multiple standard lengths — select the appropriate length for your application.
- Q: What is the maximum number of S7-300 modules that can be mounted on this rail?
- A: The 480mm rail can typically accommodate 1 power supply + 1 CPU + up to 8 signal/function modules, depending on individual module widths. Always verify your specific BOM against the rail length.
- Q: Do you provide export documentation for customs clearance?
- A: Yes. We provide commercial invoice, packing list, and certificate of conformity. Additional documentation (e.g., EUR.1, Form A) can be arranged upon request.
- Q: What is the lead time for the 6ES7390-1AE80-0AA0?
- A: Lead time depends on current stock levels. Please submit an RFQ for a real-time availability and lead time confirmation.
