Product Description

6ES5951-7LB21 is identified by Siemens as a Power Supply within the Simatic S5 family.

For replacement planning, its role is to provide the electrical supply required by compatible control hardware, helping keep controller, communication, or I/O functions energized within the intended system design. Maintenance planning should reference the installed hardware configuration.

In a SIMATIC S5 system, module selection is governed by the controller family, rack arrangement, electrical interface, and configured program. The exact article number should be matched before installation. The product remains part of the broader control and signal-handling arrangement.

Country of origin is listed as Romania.

When this product is used for lifecycle support, technicians should confirm the installed revision, connection arrangement, and system assignment rather than assuming interchangeability with a similarly named module. System drawings should be consulted before replacement.
