Product Details

• Part Number 1 6ES5490-7LA21

Product Description

6ES5490-7LA21 is identified by Siemens as a Front Connector within the Simatic S5 family.

For replacement planning, this component performs the specialized system function identified by its product designation within the associated automation platform. Its exact capabilities are determined by the installed configuration and product revision. 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 original equipment schedule should guide compatibility review.

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.
