Product Details

• Part Number 1 6ES5431-8FA11

Product Description

Siemens 6ES5431-8FA11 is a Digital Input Module for the Simatic S5 product family.

From a maintenance perspective, this class of module brings discrete field status into the control system. Typical signal sources include switches, relay contacts, permissives, and equipment-status circuits when they match the module's electrical requirements. Its role should remain distinct from that of similarly named assemblies.

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. Maintenance planning should reference the installed hardware configuration.

In the signal path, this approach helps preserve the intended system function while keeping selection aligned with the documented ratings, capacity, and compatibility requirements. Application should remain aligned with the documented system design.
