Typical Applications
- Machine tool control panels with compact S7-1500 CPU configurations
- Process automation cabinets in chemical, oil & gas, and water treatment plants
- Automotive assembly line PLC enclosures
- Building automation and HVAC control systems
- Retrofit and upgrade projects replacing S7-300/400 systems with S7-1500
- ET 200MP distributed I/O stations in field cabinets
System Compatibility
- Primary: SIMATIC S7-1500 (all CPU variants: standard, F, T, C, H)
- Primary: ET 200MP distributed I/O (IM 155-5 interface modules)
- Not Compatible: S7-300 (uses 6ES7390 series rails), S7-400 (uses 6ES7400 series racks)
- Accessory Compatibility: Works with all S7-1500 bus connectors, shielding brackets (6ES7590-1AA00-0AA0), and cable ducts
Selection Guide
Use the following criteria to select the correct mounting rail length for your S7-1500 configuration:
- Step 1 — Count modules: List all CPUs, power supplies, I/O modules, and communication modules.
- Step 2 — Calculate width: Each S7-1500 module is 25–70 mm wide. Sum total width + 20 mm clearance on each side.
- Step 3 — Select rail: Choose the next standard rail length above your calculated total (160 / 245 / 530 / 830 mm).
- Step 4 — Verify cabinet depth: Minimum cabinet depth of 210 mm required for S7-1500 with front connectors.
- Step 5 — Check grounding: Ensure PE conductor ≥ 10 mm² is connected to the rail’s grounding screw.
For configurations exceeding 830 mm, use the 2000 mm cut-to-length rail (6ES7590-1BC00-0AA0) or split into multiple rows.

Replacement & Compatibility FAQ
Q: Can I use a standard 35 mm DIN rail instead of the SIEMENS 6ES7590-1AB60-0AA0?
A: Standard DIN rails lack the S7-1500 specific hole pattern and PE grounding points. Using non-SIEMENS rails may cause module misalignment and voids system warranty. The original rail is strongly recommended.
Q: Is the 6ES7590-1AB60-0AA0 compatible with S7-300 modules?
A: No. S7-300 uses a different rail series (6ES7390-1Axxxx). The S7-1500 rail is not mechanically compatible with S7-300 modules.
Q: What is the maximum number of modules I can mount on the 160 mm rail?
A: The 160 mm rail typically accommodates 1 CPU + 1 power supply, or up to 3–4 narrow I/O modules. For larger configurations, select a longer rail.
Q: Can I cut the 6ES7590-1AB60-0AA0 to a shorter length?
A: Cutting is not recommended as it may damage the anodized surface and compromise grounding integrity. Use the 2000 mm cut-to-length rail (6ES7590-1BC00-0AA0) if a custom length is required.
Q: Do you supply the mounting screws and grounding hardware?
A: Mounting hardware is typically included with the rail. Please confirm at time of order. Additional grounding kits are available separately.
