Product Description

Siemens 6ES5440-8MA21 is a Digital Input Module for the Simatic S5 product family.

From a maintenance perspective, 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. Maintenance planning should reference the installed hardware configuration.

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. Selection should account for the intended surrounding hardware configuration.

Country of origin is listed as Germany.

In the signal path, this approach helps preserve the intended system function while keeping selection aligned with the documented ratings, capacity, and compatibility requirements. Final selection should be based on the plant's controlled-equipment records.
