Product Details

• Part Number 1 6ES5421-5AA11

Product Description

Designed for the Simatic S5 platform, Siemens 6ES5421-5AA11 is a Digital Input Module.

Within the process-control arrangement, 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. Installation should follow the control node's approved hardware records.

SIMATIC S5 is a modular PLC platform used in established machine and process-control installations. This product supports the PLC modules function assigned within the compatible S5 hardware configuration. Existing connection and module records should guide replacement work.

For maintenance or replacement work, the exact module designation should be checked against the installed hardware, wiring records, and control-system documentation before the component is placed into service. The product remains part of the broader control and signal-handling arrangement.
