A compact and safe installation solution for cable ducts

25 June 2012

The AS-Interface has simplified automation projects through its quick connection technology via flat cables. In installation technology, it is common to connect digital IO’s via distributors or modules with several IO ports. In the case of safety solutions, superfluous parallel wiring or a parallel system environment often still predominate. However, these are rendered unnecessary with AS-i Safety.

Where safe components need to be implemented in PLe in a decentralised manner, either the AS-i interface can be integrated in the safe end device, or a complete, two-channel AS-i module can be used for connection. Many different AS-i integrated devices, or sufficient space in which to install the modules are necessary as a result.

Pepperl+Fuchs believes it has ended this dilemma with the introduction of a compact G10 safety module featuring IP68/69k protection. Any safety switch with dry contacts can be connected to this ultra-compact module in a modular fashion. Whereas the flat cable would have to be fed out of the cable duct, direct installation within the cable duct is now possible thanks to the unit’s low height of <23mm. All that can be seen from outside is the round cable outlet to the safe end device. The one-piece housing enables flat cables to simply be fed through, contacted via round, gold-plated pins, while being tightly sealed at the same time, by means of a single screw.
