Front connector module with flat round cable connection for 2 A digital output modules. Power supply via screw contacts. The front connector module for SIMATIC S7-300 with screw terminals for potential supply, for connecting a 16-pin connecting cable, is a modified front connector for connecting to a digital 2 amp output module. This is plugged into the module to be wired instead of the front connector. The connecting cable is plugged in here 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 a low wiring effort, sources of error in the cabling can be significantly reduced. Actuators from the periphery are connected to the connection modules of SIMATIC TOP connect and connected to the SIMATIC S7-3000 via a connecting cable and front connector module.
