- Function modules (FM): FM 350, FM 351, FM 352, FM 353, FM 354, FM 355
- Communication modules (CP): CP 340, CP 341, CP 342, CP 343, CP 344
- Power supply modules (PS): PS 305, PS 307 series
- Interface modules (IM): IM 360, IM 361, IM 365
Selection Guide
Use the following criteria to select the correct mounting rail length for your S7-300 system:
- Module count: Each S7-300 module occupies 40 mm width. A 2000 mm rail accommodates up to ~48 single-width modules (minus PS and CPU space).
- Cabinet depth: Ensure your enclosure depth allows for the 2 m rail plus wiring clearance.
- Expansion rows: For multi-row configurations, use IM 360/361 interface modules; each row requires its own rail.
- Cut-to-length: The 2 m rail can be cut on-site if a shorter custom length is needed — use a metal saw and deburr edges.
- Grounding: Ensure the rail is properly grounded to the cabinet chassis per SIEMENS installation guidelines.
Quality Assurance & Sourcing

Replacement & Compatibility FAQ
- Q: Can I use a third-party DIN rail instead of 6ES7390-1AB60-0AA0?
- A: Standard 35 mm DIN rails are NOT compatible. The S7-300 uses a proprietary SIEMENS profile rail with specific slot pitch. Only SIEMENS 6ES7390-1Axx0-0AA0 series rails are guaranteed compatible.
- Q: Is 6ES7390-1AB60-0AA0 compatible with S7-400 or S7-1500?
- A: No. S7-400 and S7-1500 use different rail profiles. This rail is exclusively for S7-300 systems.
- Q: Can I cut the 2 m rail to a shorter length?
- A: Yes. The aluminum rail can be cut with a metal saw. Deburr all edges and re-drill ground screw holes as needed.
- Q: What is the difference between 6ES7390-1AB60-0AA0 and 6ES7390-1AJ30-0AA0?
- A: Length only — 2000 mm vs. 1000 mm. The cross-section profile and module compatibility are identical.
- Q: Do you offer project/bulk pricing?
- A: Yes. Contact support@konmask.com for volume quotes.
