Machine builders can now implement required safety functions while improving productivity with the Allen-Bradley Guardmaster 440C-CR30 safety relay from Rockwell Automation, Milwaukee, Wis.
Users can program the safety relay through the free Connected Components Workbench software, which is designed to reduce programming time and help 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 4-9 safety circuits and can control of up to five zones.
The graphical user interface and drag-and-drop capabilities help guide users through a simple process of selecting certified safety function blocks for the safety relay. Once programmed, an embedded Modbus interface allows the safety relay to easily communicate diagnostic data to Allen Bradley Micro800 controllers, Allen-Bradley PanelView graphic terminals or Allen Bradley CompactLogix controllers. Five status and 16 user-configurable LEDs on the safety relay’s faceplate provide local diagnostics to further aid in status reporting and troubleshooting.
