Siemens | Simatic S5 6ES5155-3UA21

Product Details

• Part Number 1 6ES5155-3UA21

Product Description

6ES5155-3UA21 is identified by Siemens as a Rack without 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. The product should be matched to the documented control-system position.

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 plant's maintenance records should support final product selection.

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. Final selection should be based on the plant's controlled-equipment records.
