Siemens 6ES7590-1AB60-0AA0 SIMATIC S7-1500 Mounting Rail 160 mm: Specs, Installation and Selection Guide

If you are specifying or replacing a mounting rail for a SIMATIC S7-1500 control system, you are likely already at the point of confirming the part number and verifying fit before submitting a purchase order. The Siemens 6ES7590-1AB60-0AA0 is a 160 mm aluminum DIN rail mounting component designed exclusively for the S7-1500 platform, supplied with an integrated grounding screw and built-in DIN rail profile — no separate adapters or grounding hardware required. It is a structural accessory, not a PLC module, and its selection comes down to three hard constraints: enclosure width, grounding requirements, and OEM compatibility.

If you have already confirmed this is the right part, check current pricing and availability at LeadTime.ca — ships worldwide.

Does the Siemens 6ES7590-1AB60-0AA0 Fit Your Project Requirements?

This mounting rail is the correct choice for engineers and procurement specialists who need a genuine Siemens OEM rail for an S7-1500 system build, retrofit, or replacement. It is right for your application if:

  • Your host PLC platform is confirmed as SIMATIC S7-1500 — not S7-1200, S7-300, or S7-400, which use different rail geometries
  • Your enclosure has exactly 160 mm of available rail span and a minimum of 16 mm depth clearance
  • Your installation plan requires an integrated grounding screw for electrical safety compliance
  • You need an integrated DIN rail profile for direct module snap-in — no separate rail adapter sourcing
  • You are sourcing from Siemens or an authorized distributor to guarantee OEM fit and certification

If your enclosure requires a longer rail span, you will need multiple units of the 6ES7590-1AB60-0AA0 installed in parallel, or a different S7-1500 frame configuration. If budget constraints are driving consideration of a generic DIN rail substitute, review the wrong-part checklist further down this page before proceeding — the cost of a failed safety inspection or voided warranty significantly outweighs the savings on the rail itself.

What the Siemens 6ES7590-1AB60-0AA0 Actually Does in an S7-1500 System

The 6ES7590-1AB60-0AA0 is a structural mounting platform — the physical backbone on which all SIMATIC S7-1500 CPU modules, I/O terminals, circuit breakers, and relays are anchored inside a control enclosure. It is not a functional PLC component and performs no signal processing, communication, or control logic. Its role is entirely mechanical and electrical: it provides a standardized 160 mm mounting surface with a built-in DIN rail profile for snap-in module installation, and a grounding screw that bonds the entire rail assembly to the facility ground conductor.

What makes this OEM rail the preferred choice over generic alternatives is the integration of grounding hardware and the certified DIN rail geometry into a single aluminum extrusion. The aluminum body is galvanically isolated per DIN 50015, which prevents corrosion in humid or chemically active factory environments and is rated for a typical lifespan of 10 to 15 years in standard industrial settings. The galvanic isolation also maintains the integrity of the grounding path, which is critical for both personnel safety and equipment protection in live production environments.

The SIMATIC S7-1500 platform is installed in over 50% of new manufacturing automation projects in North America, and this rail is a standard BOM line item on virtually every S7-1500 enclosure build. Its 160 mm width matches the standard enclosure spans used in S7-1500 system design, and the integrated grounding screw eliminates 2 to 4 hours of additional engineering time per installation compared to sourcing and fitting separate grounding hardware on a generic rail.

Typical S7-1500 System Architecture: Where This Rail Fits

The 6ES7590-1AB60-0AA0 sits at the physical base layer of the S7-1500 control system — it is the first component installed in the enclosure, and everything else mounts to it. Here is the typical component chain in a standard S7-1500 build:

  • Control enclosure or cabinet panel — the outer housing in which the entire system is installed
  • 6ES7590-1AB60-0AA0 mounting rail — secured to the enclosure backplate, grounded to the facility earth conductor via the integrated grounding screw
  • SIMATIC S7-1500 CPU module — snaps directly onto the integrated DIN rail profile of the mounting rail
  • S7-1500 digital and analog I/O terminal modules — mounted to the right of the CPU along the same 160 mm DIN rail profile
  • Siemens circuit breakers, relays, and contactors — also mounted on the integrated DIN rail for system protection and power distribution

Who Uses This Rail and in What Installations

In greenfield manufacturing projects — new production lines, batching systems, and machinery control panels — the 6ES7590-1AB60-0AA0 is a standard first-order item. Controls engineers specify it as part of the S7-1500 BOM before enclosure fabrication begins, since the 160 mm rail width drives enclosure panel layout decisions.

Retrofit projects modernizing S7-300 or S7-400 legacy systems to the current S7-1500 standard require this rail as part of the enclosure redesign. The S7-1500 rail geometry is not backward-compatible with older systems, so a new 6ES7590-1AB60-0AA0 is a mandatory component in every S7-300 or S7-400 migration.

Plant maintenance teams also order this rail as an emergency replacement when an existing rail is corroded, physically deformed, or has a failed grounding screw. Because the part is typically in stock at major distributors with a 1-day ex-works lead time, it supports urgent replacement scenarios without extended line downtime.

OEM machine builders sourcing rails for multiple units benefit from consistent part numbering across their equipment fleet, simplifying spare parts management and ensuring that every machine in the field uses the same certified, grounded mounting platform.

Application Typical Deployment
New S7-1500 control panel build Single or multiple rails per enclosure, specified in system BOM before fabrication
S7-300 / S7-400 modernization retrofit Replacement of legacy rail as part of full S7-1500 migration; new enclosure layout required
Emergency rail replacement (maintenance) One-for-one replacement of corroded or damaged rail; in-stock availability critical
System expansion or reconfiguration Additional rail added in parallel to accommodate new I/O modules or protective devices
OEM machine builder multi-unit production Multiple units ordered per machine build cycle; consistent part number across fleet

Expert Verdict: Honest Assessment for Engineers and Procurement Teams

The 6ES7590-1AB60-0AA0 does exactly what it is supposed to do, and it does it well. For any standard SIMATIC S7-1500 enclosure build, this is the correct part — period. The integrated grounding screw and DIN rail profile in a single 160 mm aluminum extrusion eliminate the sourcing friction and installation risk of assembling equivalent functionality from generic components. The galvanic isolation per DIN 50015 is not marketing language; it is a measurable material specification that matters in the food processing, pharmaceutical, and water treatment environments where S7-1500 systems are routinely deployed. The S7-1500 product family has been in continuous production for over 12 years, and Siemens distributes this rail globally through a stable network of authorized distributors — obsolescence risk is low.

Where this part has real limits: it is a single fixed width. If your enclosure layout requires a longer span than 160 mm, you are ordering multiple units or rethinking your frame configuration — there is no longer version in the 6ES7590-1AB60-0AA0 family. Buyers facing tight budget pressure sometimes ask about generic DIN rail alternatives, and the honest answer is that the cost savings disappear quickly when you factor in the grounding hardware, the certification gap, and the real possibility of a failed commissioning inspection. If cost reduction on the mounting rail is a genuine project constraint, escalate it to a formal value-engineering review rather than a unilateral substitution.

Installation and Grounding Overview

The following is an overview of installation requirements. Engineers should refer to the official Siemens S7-1500 system integration manual for complete procedures and torque specifications.

  • Position the rail horizontally in the enclosure and align the rear mounting holes with the enclosure backplate; confirm 160 mm width and 16 mm depth clearance before fastening
  • Secure the rail using industrial-grade fasteners — hand-tighten first, then torque to the value specified in the Siemens installation manual; do not over-tighten aluminum mounting points
  • Connect the integrated grounding screw to the facility ground bus or cabinet PE terminal using an appropriately rated copper conductor; this connection is mandatory, not optional
  • Verify grounding continuity with a digital multimeter — resistance from the grounding screw to the main ground bus should be less than 1 ohm before modules are installed
  • Document the measured grounding resistance value in the commissioning report as a baseline for future maintenance inspections

Compatible S7-1500 Modules and Devices

The 6ES7590-1AB60-0AA0 is designed to accept the full range of SIMATIC S7-1500 hardware via its integrated DIN rail profile. The following device categories mount directly to this rail:

  • SIMATIC S7-1500 CPU modules — all standard models in the S7-1500 family
  • SIMATIC S7-1500 digital I/O terminal modules — standard DIN rail snap-in mounting
  • SIMATIC S7-1500 analog I/O terminal modules — standard DIN rail snap-in mounting
  • Siemens circuit breakers — direct DIN rail mounting for system protection
  • Siemens relays and contactors — direct DIN rail mounting for switching and protection functions
  • Multiple 6ES7590-1AB60-0AA0 rails installed in parallel — for larger S7-1500 configurations requiring more than the capacity of a single 160 mm rail span; consult Siemens documentation for layout guidance

This rail is not compatible with SIMATIC S7-1200, S7-300, or S7-400 systems, which use different rail geometries. It is also not interchangeable with third-party PLC mounting hardware.

Wrong-Part Prevention Checklist Before You Order

Before submitting a purchase order for the 6ES7590-1AB60-0AA0, verify each of the following items against your system documentation and enclosure drawings:

  1. Confirm the host PLC system is SIMATIC S7-1500, not S7-1200, S7-300, or S7-400 (different rail geometries)
  2. Verify width requirement is exactly 160 mm before ordering; measure existing enclosure space
  3. Ensure grounding screw and integrated DIN rail features are required by your installation plan
  4. Check that the 155 mm height and 16 mm depth fit your enclosure layout (review CAD or physical space)
  5. Confirm you need only one rail; larger systems may require multiple units
  6. Do not confuse this part with S7-1500 module covers, end plates, or termination modules

If all six checks pass, you have the right part. Confirm availability and pricing at LeadTime.ca, or contact our team if you need to verify lead time for a specific project schedule.

Frequently Asked Questions

Can the 6ES7590-1AB60-0AA0 be used with an S7-1200 or S7-300 system?

No. This rail is designed exclusively for the SIMATIC S7-1500 platform. The S7-1200, S7-300, and S7-400 systems use different rail geometries that are not mechanically compatible with the 6ES7590-1AB60-0AA0. Attempting to use this rail with other system families will result in modules that do not seat correctly and potential safety compliance failures.

How many S7-1500 modules can fit on a single 6ES7590-1AB60-0AA0?

Module capacity depends on the physical width of each individual module. A typical S7-1500 configuration accommodates 4 to 8 modules on a single 160 mm rail, depending on the mix of CPU, I/O terminals, and protective devices installed. For configurations requiring more modules, multiple 6ES7590-1AB60-0AA0 rails can be installed in parallel — consult Siemens system documentation for the specific layout guidance.

Is connecting the grounding screw mandatory, or can I skip it?

Grounding is mandatory — it is both a safety requirement and a regulatory compliance requirement. The integrated grounding screw must be connected to the facility ground or cabinet PE terminal before the system is energized. An ungrounded rail creates shock hazard, stray voltage risks, and potential equipment damage, and an ungrounded system will fail electrical safety inspections in virtually every industrial jurisdiction worldwide.

My enclosure is wider than 160 mm — what are my options?

The 6ES7590-1AB60-0AA0 is available only in the 160 mm width. For enclosures requiring longer rail spans, the standard approach is to install multiple 160 mm rails side by side, with each rail independently grounded via its own grounding screw. Alternatively, a pre-configured S7-1500 frame kit may be appropriate for your enclosure design. Consult Siemens documentation or an authorized integrator for layout guidance specific to your enclosure model.

Can this rail be used in an outdoor installation?

The 6ES7590-1AB60-0AA0 carries an IP20 rating, which means it requires installation inside a weatherproof enclosure rated IP65 or higher for outdoor applications. The rail itself is protected by its galvanically isolated aluminum body, but it must not be exposed directly to weather, moisture, or contaminants without an appropriate outer enclosure.

What is the typical lead time for the 6ES7590-1AB60-0AA0?

The ex-works lead time is 1 day for stock orders, and the part is routinely held in inventory at major authorized distributors worldwide. For urgent replacement scenarios, same-day or next-business-day shipping is available from stocked locations. For volume orders or project-specific delivery schedules, contact LeadTime.ca directly to confirm availability and lead time before committing to a build timeline.
