Machine builders can now easily implement required safety functions while improving productivity with the Allen-Bradley Guardmaster 440C-CR30 safety relay from Rockwell Automation. Users can program the safety relay through the free Connected Components Workbench software from Rockwell Automation. Connected Components Workbench software reduces programming time and helps increase productivity by allowing users to create, control and monitor a safety system in the same software environment as their standard control. The Guardmaster 440C-CR30 safety relay meets PLe, SIL 3 per EN ISO 13849-1 and IEC 62061. It is ideal for applications requiring four to nine safety circuits and control of up to five zones.
