Front connector module with flat ribbon Cable connection for analog (40 pins) Modules of the S7-300 Power supply over Screw terminals The front connector module for SIMATIC S7-300 with screw terminals for potential feed to connect 4×16-pole cables represents a modified front connector for connection to a analog I/O module. This is plugged into the module to be wired instead of the front connector. Here the cables are plugged in and connected to the connection module.This modified front connector module is part of the fully modular connection of SIMATIC TOP connect for the fastest and safest system cabling. In addition to low wiring costs, error sources in cabling can be significantly reduced. Sensors and actuators from the peripherals are attached to the connection modules of SIMATIC TOP connect and linked to the SIMATIC S7-300 via connecting cable and front plug-in module.
