Siemens | Simatic S7 6ES7523-1BL00-0AA0

Product Details

• Part Number 1 6ES7523-1BL00-0AA0

Product Description

6ES7523-1BL00-0AA0 is identified by Siemens as a Digital Input Output Module within the Simatic S7 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. Selection should account for the intended surrounding hardware configuration.

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 original equipment schedule should guide compatibility review.

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.
