Product Details
- Part Number 1 6ES7421-1EL00-0AA0
Product Description
The product identified as Siemens 6ES7421-1EL00-0AA0 is a Digital Input Module in the Simatic S7 hardware family.
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. Ratings and capacity should be verified against the exact model documentation.
SIMATIC S7 integrates programmable control, modular I/O, and industrial communication functions. This product belongs to the PLC modules layer of the installed S7 automation solution. This is relevant where the installation calls for this specific component class.
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.
