Siemens | Simatic S7 6ES7421-7DH00-0AB0

Product Details

• Part Number 1 6ES7421-7DH00-0AB0

Product Description

Designed for the Simatic S7 platform, Siemens 6ES7421-7DH00-0AB0 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 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. System drawings should be consulted before replacement.

For ongoing lifecycle support, proper application depends on matching the product to the original control-system design, including its physical position, electrical connections, and configured relationship with surrounding hardware. Connection and configuration should follow the requirements of the platform.
