Product Description

For Simatic S7 system applications, Siemens 6ES7421-5EH00-0AA0 provides the function of a Digital Input Module.

For replacement planning, this class of module brings discrete field status into the control system. Typical signal sources include switches, relay contacts, permissives, and equipment-status circuits when they match the module's electrical requirements. The documented module assignment should remain the basis for selection.

Within an S7 installation, the exact hardware order number determines supported interfaces and configuration behavior. System and software compatibility should be checked before replacement. The installed revision should be confirmed before the product is applied.

Country of origin is listed as United States of America.
