Until now, high installation and commissioning costs have been generated by the conventional method of wiring the PLC to the control periphery (single conductor connection).

 

With the PLC-Interface family of products, Weidmüller is offering the user a convenient and a quickly installed output level for all current PCL controls; for example, from the companies: SIEMENS and GROUPE SCHNEIDER.

The product spectrum includes:

• PLC-specific front adapters
• Passive components with screw and tension clamp connection elements
• Active components with screw and tension clamp connection elements
• Pre-assembled control cables
  

The specific front adapters replace the current screw connection technology of the input and output cards of the PLC. The PLC signals are transmitted to the active or passive components via 40-pole or 10-pole pre-assembled control cables.

 

The PLC signals are converted either:

• in double-word form via a flat-strip connection or
• byte-for-byte via 10-pole flat-strip connections
  

System wiring offers the following advantages over point-to-point wiring:

• Reduces planning and design times
• Reduces installation time
• Reduces commissioning  and troubleshooting efforts
• Plug& Play due to simple swapping of input/output interfaces
• Minimises wiring efforts and avoids wiring errors (tested cables)

 

Additional user benefits are status indication, signal isolation, fusing, and disconnecting, which reduce the wiring effort.
