Product Details

  • Part Number 1 6ES5451-7LA21

Product Description

Designed for the Simatic S5 platform, Siemens 6ES5451-7LA21 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. The surrounding rack and module arrangement should be reviewed before installation.

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. Exact operating details should be taken from the installed model documentation.

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 original equipment schedule should guide compatibility review.
