6ES5930-7AA11 Siemens | S5 PLC Power Supply for Automation

Product Description

The Siemens 6ES5930-7AA11 is a power supply module designed for SIMATIC S5 programmable logic controller systems. It converts standard AC mains voltage into stable DC output, providing 5 V for logic circuits and 24 V for I/O modules. Moreover, this module ensures reliable operation by protecting against short circuits, overloads, and thermal issues, maintaining consistent performance in demanding industrial environments.

Although the S5 series is a legacy platform, the 6ES5930-7AA11 remains available as a spare part, supporting long-term operation of existing installations. Its compact rack-mount design allows seamless integration alongside CPU and I/O modules, making it ideal for manufacturing, process automation, and energy systems where reliable power delivery is critical.
