For Simatic S7 system applications, Siemens 6ES7131-1BL00-0XB0 provides the function of an S5 Digital Input 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. The documented module assignment should remain the basis for selection.
Country of origin is listed as Germany.
In the signal path, this approach helps preserve the intended system function while keeping selection aligned with the documented ratings, capacity, and compatibility requirements. Existing connection and module records should guide replacement work.
