Front connector module with 4x16-pin IDC connection for digital 32 I/O modules of the S7-1500 Potential supply via push-in terminal The front connector module for SIMATIC S7-1500 with push-in terminals for potential supply, for connecting 16-pin connecting cables represents a modified front connector for connection to a digital I/O module. This is plugged into the module to be wired instead of the front connector. The connecting cables are 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 low wiring effort, sources of error in the cabling can be significantly reduced. Sensors and actuators from the periphery are connected to the connection modules of SIMATIC TOP connect and connected to the SIMATIC S7-1500 via a connecting cable and front connector module.
