Product Description

6ES7521-1FH00-0AA0 is identified by Siemens as a Digital Input Module within the Simatic S7 family.

For replacement planning, a digital input module receives discrete on/off states from field contacts and devices, then makes those states available to the controller for monitoring, sequencing, alarms, and interlocks. The assigned system function should be preserved through installation and service.

Within an S7 installation, the exact hardware order number determines supported interfaces and configuration behavior. System and software compatibility should be checked before replacement. The installed revision should be confirmed before the product is applied.

Country of origin is listed as Germany.

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.
