For the connection to the signal module (integrated I/O for the compact CPUs, digital and analog), the front connector module is plugged into the signal module instead of the SIMATIC S7-300 front connector. It has 2 to 4-pin plugs for the connection of the connecting cables and 2 to 4 connections for potential infeed. There are different versions for the connection of the compact CPUs (X1), digital 24 V/0.5 A I/O signals 16-channel and 32-channel, for digital 24 V/2 A output modules and for analog I/O modules.
