For Simatic S7 system applications, Siemens 6ES7223-1BH32-0XB0 provides the function of a Digital Input Output Module.
For replacement planning, digital input hardware creates the path from field-level status signals to control logic, allowing the system to evaluate operating conditions and respond through configured sequences or protective actions. 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. Maintenance planning should reference the installed hardware configuration.
Country of origin is listed as China.
In the signal path, this approach helps preserve the intended system function while keeping selection aligned with the documented ratings, capacity, and compatibility requirements. Application should remain aligned with the documented system design.
