Siemens 6ES7-390-1AF30-0AA0 SIMATIC S7-300 mounting rail 530mm.

The Siemens 6ES7-390-1AF30-0AA0 is a 530mm mounting rail designed for the SIMATIC S7-300 programmable logic controller (PLC) series. This DIN rail provides the mechanical foundation for mounting S7-300 system modules, including CPU units, interface modules, signal modules, and power supplies within industrial automation cabinets.

The mounting rail is an essential structural component for building S7-300 automation systems, allowing multiple modules to be securely installed in a linear configuration. It features the standard profiled design that enables snap-on mounting of S7-300 components, with integrated bus connectors linking the modules together.

The SIMATIC S7-300 is a legacy PLC platform that has been widely deployed in manufacturing, process control, and industrial automation applications. While Siemens has transitioned to newer platforms such as the S7-1500, the S7-300 remains in active service across many installed bases, maintaining demand for replacement and expansion components.
