Features:
- Fits standard industrial cabinets; compatible with all S7-400 modules.
- Galvanized steel; pre-drilled mounting holes for secure cabinet attachment.
- Drop-in replacement for original S7-400 mounting rails; no modification or configuration needed.
The 6ES7492-1AL00-0AA0 measures exactly 482 mm (19 inches), the standard width for industrial control cabinets worldwide. This ensures a perfect fit in existing S7-400 installations without cutting or custom fabrication. The rail supports all standard S7-400 modules – CPUs, power supplies, digital/analog I/O cards, communication processors, and function modules. Modules clip onto the rail using their built-in latches and are secured with screws. The 19‑inch form factor allows the rail to be mounted horizontally or vertically, depending on cabinet layout.
The 6ES7492-1AL00-0AA0 is manufactured from galvanized steel, providing corrosion resistance and mechanical strength. The rail can support the weight of multiple S7-400 modules without bending or flexing, even in high‑vibration environments such as machine tool controls or mobile equipment. Pre‑drilled holes at regular intervals allow secure attachment to the cabinet backplate using M6 screws or similar fasteners. The rail surface is designed to accept the standard S7-400 module clips, ensuring a firm, rattle‑free connection. Unlike plastic mounting solutions, this metal rail also serves as a low‑impedance ground path when properly bonded to the cabinet earth.
The 6ES7492-1AL00-0AA0 is available as a spare part for SIMATIC S7-400 systems, many of which are no longer in active production. When the original mounting rail becomes damaged – bent, corroded, or with stripped threads – replacing it with this exact model avoids the need for custom drilling or adapter plates. The replacement process is straightforward: power down the system, remove all modules from the old rail, unscrew the rail, mount the new 6ES7492-1AL00-0AA0 in the same position, and reinstall the modules. No configuration, software changes, or rewiring are required. Slot addressing remains unchanged because the physical order of modules is preserved.
The 6ES7492-1AL00-0AA0 Siemens SIGNAL MODULES may still be available for purchase and support from Apter Power beyond
End-Of-Life (EOL) by the manufacturer (OEM).

- High-end process control: such as automotive manufacturing, chemical industry, and power plants.
- Complex mechanical engineering: used in automated warehouses, large machine tools, and automated production lines.
- Signal-intensive tasks: specifically designed for connecting S7-400 digital or analog input/output modules.
- Module Replacement Protection: Equipped with a mechanical coding mechanism, it prevents the connector from being incorrectly inserted into different types of modules during maintenance, reducing the risk of misconnection.
- Simplified Maintenance Diagnosis: When replacing a faulty module, the wiring remains on the connector. This significantly reduces the Mean Time To Repair (MTTR) and avoids human error caused by rewiring.
- Physical Connection Protection: Utilizes a 48-pin crimp design to ensure stable and safe signal transmission under high current or vibration conditions.
- Installation Requirements: Use standard screw-on wiring; multi-core wires are supported. Installation requires the specific slot corresponding to the S7-400 module.
- Product Lifecycle: Siemens has announced that this product will officially enter the product phase-out phase on October 1, 2025.
- Spare Parts Recommendation: Some stock is still available and can be obtained from the Siemens Industry Mall or authorized spare parts providers such as PLC-City.
