Product Details

Product Description

6ES5242-5AA21 is identified by Siemens as a Counter Module within the Simatic S5 family.

Within the control architecture, this product serves the equipment role stated in its description and should be selected by exact model identity rather than by appearance or a broadly similar name. The installed revision should be confirmed before the product is applied.

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 should be matched to the documented control-system position.

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. Application should remain aligned with the documented system design.
