Front connector module with 4x16 pole IDC connector for digital 32 I/O modules of the S7-1500 Potential supply over Screw terminals The front connector module for SIMATIC S7-1500 with spring terminals for potential feed to connect 2x16-pole 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. 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.
