The PROTECT PSC1 safety controller is compact, has a modular structure and can be used extremely flexibly. The PSC1 makes it possible to project tailor-made safety-related solutions, whether for individual machines or highly complex installations. Furthermore, the PSC1 can make a contribution towards the realisation of Industry 4.0 concepts.
The PROTECT PSC1 consists of freely programmable compact PLCs with IO extension modules for signal processing of mechanical and electronic safety switchgear. The compact controllers can be equipped with a universal communication interface. This enables the selection and implementation of different fieldbus protocols easily using software. The PSC1 therefore only requires one hardware element to create a connection to most common forms of fieldbus systems – which is a significant advantage, particularly considering aspects of cost.
The modular structure of the new Schmersal control system is of interest particularly with regard to Industry 4.0 concepts. The aim here, among other things, is to produce individualised products up to single units cost effectively. To achieve this, modularly assembled systems are often needed in which control functions are distributed on smaller, decentralised units that are networked together. Here, the PSC1 from Schmersal offers the means to configure individual protection systems on a software basis. Furthermore, safe communication between different PSC1 controllers is facilitated via Ethernet SDDC (Safe Device to Device Communication). This simplifies the setup of complex, multi-part installations with networked safety subsystems.
Another advantage of PSC1: Owing to the optionally integrated SD bus gateway, additional non-secure diagnostic signals from connected sensors can be transmitted via a standard bus system to an automation control system. This also allows signals to be evaluated that are relevant for preventing downtimes and increasing plant availability – and this in turn facilitates a rise in efficiency.
