Siemens 6ES7590-1AF30-0AA0 SIMATIC S7-1500 Mounting Rail 530mm (20.9in) PLC Accessory

The Siemens 6ES7590-1AF30-0AA0 is a SIMATIC S7-1500 mounting rail measuring 530mm (20.9 inch), made of tin-plated aluminum and supplied with a grounding screw. It provides the DIN rail base for an S7-1500 CPU and I/O modules and accepts incidentals such as terminals, circuit breakers and relays mounted alongside the rack on the same integrated DIN profile.

Selection Notes

At 530mm this rail gives roughly 48mm more mounting width than the standard 19 inch rail, which is useful once a station's module count runs past what a single 19 inch bay holds. The integrated DIN profile still accepts terminals, circuit breakers or relays alongside the S7-1500 modules on the same rail, and the included grounding screw provides the reference-potential connection the system needs for correct EMC performance and reliable shield bonding. Pick the shorter 482.6mm rail instead when the planned configuration fits a standard 19 inch cabinet width, since the extra length otherwise just adds unused panel space and weight without giving any functional benefit to the installation.

Applications

Mounting base for larger S7-1500 stations with additional I/O modules that exceed the standard 19 inch rail width in industrial control cabinets, and for panels where extra rail length is reserved ahead of time for future expansion without re-wiring the existing rack when new modules are added later.
