Siemens | Simatic S7 6ES7221-3AD30-0XB0

Product Details

• Part Number 1 6ES7221-3AD30-0XB0

Product Description

6ES7221-3AD30-0XB0 is identified by Siemens as a Digital Input Signal Board within the Simatic S7 family.

For replacement planning, digital input hardware creates the path from field-level status signals to control logic, allowing the system to evaluate operating conditions and respond through configured sequences or protective actions. Connection and configuration should follow the requirements of the platform.

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 documented module assignment should remain the basis for selection.

In the signal path, this approach helps preserve the intended system function while keeping selection aligned with the documented ratings, capacity, and compatibility requirements. Configuration records should be reconciled with the exact installed assembly.
