Siemens | Simatic S5 6FM1721-3AA20

Product Details

• Part Number 1 6FM1721-3AA20

Product Description

For Simatic S5 system applications, Siemens 6FM1721-3AA20 provides the function of a Positioning Module.

For replacement planning, this class of component belongs to the position loop, where feedback and control functions are coordinated for compatible servo, actuator, or turbine equipment. 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. Final selection should be based on the plant's controlled-equipment records.
