Siemens | Simatic S5 6ES5721-4BF00

Product Details

• Part Number 1 6ES5721-4BF00

Product Description

Siemens 6ES5721-4BF00 is a Cable for the Simatic S5 product family.

From a maintenance perspective, its purpose is to connect specific system components without altering the assigned signal path. Replacement selection should be based on the exact connectors and installed routing requirements. The original wiring and configuration records should guide application.

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. Its role should remain distinct from that of similarly named assemblies.

In the signal path, this approach helps preserve the intended system function while keeping selection aligned with the documented ratings, capacity, and compatibility requirements. Installation should follow the control node's approved hardware records.
