System Architecture & Signal Flow
The A5E03480675 mounts directly onto the S7-300 profile rail at the leftmost position of the rack. AC mains power enters through the module’s terminal block, is rectified and regulated internally, and 24 V DC is distributed via the backplane bus to the CPU and all installed I/O modules. The module’s LED status indicator provides immediate visual confirmation of power-good status, enabling rapid fault isolation during commissioning and maintenance.
