Small, fast and safe: the Cube20S modular fieldbus station
28 April 2015
Murrelektronik is offering safety expansion modules for its Cube20S modular fieldbus station that enable the reliable transfer of safety-related data.
Cube20S is a compact, cabinet mountable, adaptable fieldbus system. Its digital and analogue modules (available with two, four or eight channels) as well as its function modules are connected to a basic module with an integrated bus node.
These new safety expansion modules can be used to create functional safety for machines and systems. By using the Profinet/ProfiSafe and Profibus/ProfiSafe safe fieldbus protocols, data is transferred in a way that allows Performance Level e (PLe) safety category to be reached.
The output module ensures that outputs are switched off safely, if necessary, and ensures affected machine components are shut down safely. The safety input module transfers signals from safety equipment (light barriers and light curtains, position switches or emergency stop buttons) to the safety controller.
