Product Details

• Part Number 1 6ES5430-4UA12

Product Description

Siemens 6ES5430-4UA12 is a Digital Input Module for the Simatic S5 product family.

From a maintenance perspective, 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. The installed revision should be confirmed before the product is applied.

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 should be matched to the documented control-system position.

In the signal path, this approach helps preserve the intended system function while keeping selection aligned with the documented ratings, capacity, and compatibility requirements. Service decisions should reflect the configured signal and control function.
