概述

Flexible connection of the cabling system consists of a S7-1500 front connector which has the 20 or 40 single cores already in place and which directly connects the I/O modules (35 mm design) with the sensors and actuators inside the control cabinet. With a cross-section of 0.5 square mm, the single wires are also suitable for higher currents and are available in different lengths and versions: as H05V-K cores (PVC insulation), H05Z-K (halogen-free insulation) or with UL/CSA certified cores. The halogen-free version has a low smoke gas density in the event of a fire and is thus particularly well suited for use in buildings.

優勢

• Individual cores can be routed directly to each element in the control cabinet
• Higher currents possible thanks to greater cross-section with lower voltage drop
• Reduction in wiring overhead through simple connection of the pre-assembled cable to the I/O modules (35 mm design)
• Easy wiring. The number printed on the cores corresponds to the connection point on the I/O connector
• Clear control cabinet wiring thanks to bundled individual cores

設計

Up to 16 or 32 digital input and output channels can be connected directly to the I/O (35 mm design) with a front connector with single wires. The single wires are fitted with screw-type contacts in the front connector and are cut off straight at the other end. The cores have a cross section of 0.5 mm² and can be easily assigned since they are coded in accordance with the pin designations on the front connector. Cable ties combine the single cores into a bundle.

The front connectors with single cores are available in the following lengths: 2.5 m, 3.2 m, 5.0 m, 6.5 m, 8.0 m and 10.0 m. Special lengths available on request.

The single cores are available in different versions:

• Core type H05V-K is used for industrial applications.
• The UL/CSA-approved core is available for exports to North America.
• The halogen-free version is used where low smoke gas density in the event of fire is required, e.g. in building automation
