FAQ:

What is the Siemens 6ES7590-1AB60-0AA0 and what is it used for?
This is a standard 35 mm DIN‑rail mounting rack (S7‑1500 profile rail) with a length of 160 mm. It is a mandatory mechanical component in every SIMATIC S7‑1500 PLC installation. All S7‑1500 modules—CPU, signal modules, communication processors, and power supplies—clip directly onto this rail. It provides both physical support and the electrical functional earth connection for the system.
Which S7‑1500 modules are compatible with this 160 mm mounting rail?
All standard S7‑1500 system modules, including compact CPUs (e.g., CPU 1511‑1 PN, CPU 1512C), standard signal modules (DI/DO/AI/AO), technology modules (TM), and communication processors (CP) can be snapped onto this rail. The 160 mm length is designed for small configurations—typically a CPU plus one or two I/O modules, or a standalone CPU module. Larger systems require longer rails (245 mm, 482 mm, 530 mm, 830 mm).
How do I mount the S7‑1500 rail to a backplane or panel?
The rail has pre‑drilled mounting slots for M6 screws. You can fix it directly to a metal mounting plate, control cabinet backplane, or a standard DIN‑rail adapter. The slots allow lateral adjustment, so you can position the rail precisely before tightening the screws. Siemens recommends using the ground‑contacting screws provided with the rail or system to ensure a reliable chassis ground connection.
Does the rail serve as a protective earth (PE) connection for the modules?
Yes. The rail is the central functional earth (FE) bus for the S7‑1500 system. Each module makes contact with the rail via metallic spring clips on its rear side. The rail must be properly grounded to the cabinet’s PE busbar using the dedicated grounding screw and a short, low‑impedance cable. This ensures proper EMC performance and safety.
What is the exact profile and material of the rail?
It is a 35 mm wide, 15 mm high C‑shaped DIN‑EN 60715 profile rail made of thick, rigid steel (or a composite equivalent) designed specifically for the weight of S7‑1500 modules. The rail is significantly stiffer than a standard EN 50022 DIN rail because S7‑1500 modules are heavier than typical industrial control products.
How long is the 6ES7590-1AB60-0AA0 rail, and how many modules can I fit on it?
The rail is exactly 160 mm long. This length is ideal for a small PLC station: you can typically mount one compact CPU (e.g., CPU 1511‑1 PN) and one or two slim signal modules, or a CPU plus a communication processor. The exact number depends on the module widths; always check the physical dimensions in the S7‑1500 system manual before ordering. If you need more space, choose the 245 mm (6ES7590-1AB70-0AA0) or 482 mm (6ES7590-1AB80-0AA0) rail.
Can I connect two 160 mm rails together to make a longer rack?
No, Siemens does not support joining two rails end‑to‑end mechanically or electrically. You must order the correct length rail for your total module width. Using two separate rails would break the backplane bus and the functional earth continuity. If your system outgrows the 160 mm rail, replace it with a longer S7‑1500 profile rail of the appropriate size.
Is the 6ES7590-1AB60-0AA0 compatible with S7‑1200 modules? What about ET 200MP?
S7‑1200 modules use a different mechanical design and are not directly compatible with the S7‑1500 mounting rail. However, the ET 200MP distributed I/O system uses the exact same S7‑1500 rack and rail, so this 160 mm rail can be used for an ET 200MP station with an IM 155‑5 PN interface module and I/O modules. For S7‑1200, you need the dedicated S7‑1200 DIN‑rail.
Does the rail include any accessories, or do I need to order grounding screws separately?
The rail itself is a single mechanical part. It includes the pre‑drilled mounting slots but does not come with screws, washers, or the grounding conductor. The grounding screws and PE connection cable are typically included with the S7‑1500 CPU or the power supply module, or can be ordered as a separate accessory (e.g., the S7‑1500 grounding kit). Always follow the installation manual to ensure a compliant grounding setup.
What are the most common applications for the 160 mm S7‑1500 rail?
It is used in compact machine control panels, small standalone automation cells, lab test setups, and distributed ET 200MP stations with only a few modules. Its small size saves cabinet space and is perfect for proof‑of‑concept builds, educational trainers, and low‑channel‑count OEM machines where the full‑length rails would be unnecessarily large.
