Properties of the connection technology Explanation
Twistable front connector Rapid module exchange during maintenance
(cable duct remains closed)
Pre-wiring positioning
• Efficient module wiring (easily accessible)
• No loosening of the wiring when replacing a
module
• No electrical damage to the module is
possible, because it is not yet electrically
connected
Development of potential groups by the insertion
of potential bridges
Reduced wiring effort on the front cable
connector
Integrated EMC concept (power supply element,
shielding bracket, and terminal element)
Optimization of the interference emission and
interference immunity
Consistent pin assignment of the module types Minimization of wiring errors
Consistent 40-pin front connector for all modules,
with a width of 35 mm
Simplified ordering
Two snap-in positions of the front cover Flexible cable storage space
Automatic coding of the I/O modules and front
cable connectors
Safe replacement of modules
