Siemens | Simatic S5 6ES5440-8MA22

Product Details

• Part Number 1 6ES5440-8MA22

Product Description

Siemens 6ES5440-8MA22 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. The product remains part of the broader control and signal-handling arrangement.

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 original equipment schedule should guide compatibility review.

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.
