Siemens | Simatic S5 6ES5721-5BD20

Product Details

• Part Number 1 6ES5721-5BD20

Product Description

6ES5721-5BD20 is identified by Siemens as a Cable within the Simatic S5 family.

For replacement planning, this cable provides a defined interconnection within the automation platform, preserving the wiring relationship intended between compatible modules or assemblies. Its role should remain distinct from that of similarly named assemblies.

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. Service decisions should reflect the configured signal and control function.
