Within the Simatic S7 product line, Siemens 2731102 serves as a Termination Board.
From a maintenance perspective, this type of unit concentrates field connections at a defined termination point before signals reach the related control-system electronics. Correct pairing with the associated I/O hardware is essential. 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 original wiring and configuration records should guide application.
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.
