I/O system for safety applications

14 October 2014

The Profisafe modules of Phoenix Contact’s Axioline F I/O system now enable implementation of safety applications.

Based on Profinet and Profibus, these modules enable the acquisition and output of safety-related signals in the control cabinet.

The devices are characterised by their low-stress, delayed switch-off irrespective of bus faults due to integrated stop category 1. The channel-based diagnostic messages ensure a high system availability. Their resistance to interference is due to their co-ordinated switching behaviour under capacitive and inductive loads. Being completely integrated with the controller manufacturer’s engineering tool, the devices speed up the engineering process and simplify start-up.

>The Profisafe modules are compliant with specification V2 and possess outputs with capacitive loads of up to 10 µF and 2A rated current. They meet safety integrity requirements up to SIL CL 3 and offer a performance level of up to PL e.
