Siemens | Simatic S5 6ES5900-7AA21

Product Details

• Part Number 1 6ES5900-7AA21

Product Description

6ES5900-7AA21 is identified by Siemens as a CPU Module within the Simatic S5 family.

Processor and controller modules execute configured control functions, coordinate data from I/O and communication resources, and manage the operating sequence assigned to their control node. The documented module assignment should remain the basis for selection.

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 original wiring and configuration records should guide application.

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. Ratings and capacity should be verified against the exact model documentation.
