Siemens | Simatic S5 6ES5705-3CD21

Product Details

• Part Number 1 6ES5705-3CD21

Product Description

6ES5705-3CD21 is identified by Siemens as a Cable within the Simatic S5 family.

System cables carry power, signals, or communication between designated control-system assemblies. Connector type, pin assignment, routing, and required length must match the installed equipment. The original equipment schedule should guide compatibility review.

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 remains part of the broader control and signal-handling arrangement.

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.
