Flexible Connection


Flexible Connection

The flexible connection for the SIMATIC S7-300 and S7-400 consists of clearly bundled single cores, which are already wired at the front connector. With a core cross-section of 0.5 mm², higher currents can also be carried.

The individual cores can be routed to any element in the control cabinet – quickly, easily and flexibly. Since each core is clearly marked – by a printed number corresponding to the connection point of the module – there are no more mix-ups. Order and clarity prevail in the control cabinet. 


  • Individual cores can be directly routed to each element in the control cabinet

  • Reduction of the wiring work through simple plugging in of the pre-assembled cable into the I/O module

  • Higher currents possible through larger cross-section, lower voltage drop

  • Easy wiring: the number printed on the cores corresponds to the connection point at the front connector

  • Improved clarity of the control cabinet wiring through bundled single cores

  • Front connector available with screw connection as well as crimp connection  

  • Selected screw connection versions available with UL/CSA-certified single cores
