SIMATIC S7-300
Connection methods
Flexible connection
■ Benefit
The flexible connection ensures that there is a fast and direct
connection between the input/output modules of the SIMATIC
S7-300 and the individual elements in the switchgear cabinet.
Single cores aleady attached reduce wiring overheads.
• Individual cores can be routed directly to each element in the
control cabinet.
• Higher currents are possible usin g a larger cross-section, with
a smaller voltage drop.
• Reduction in the wiring overhead through simple plugging-on
of the preassembled cable onto the I/O module
• Simple wiring. The number printe d on the core corresponds to
the connection point on the I/O connector
• Clear control cabinet wiring thanks to bundled individual
cores
