Product Details
- Part Number 1 6ES5430-8MC21
Product Description
6ES5430-8MC21 is identified by Siemens as a Digital Input Module within the Simatic S5 family.
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 original equipment schedule should guide compatibility review.
In a SIMATIC S5 system, module selection is governed by the controller family, rack arrangement, electrical interface, and configured program. The exact article number should be matched before installation. Its role should remain distinct from that of similarly named assemblies.
When this product is used for lifecycle support, technicians should confirm the installed revision, connection arrangement, and system assignment rather than assuming interchangeability with a similarly named module. System drawings should be consulted before replacement.
