Flexible safety relay solution allows multiple safety zones
The Allen-Bradley Guardmaster 440C-CR30 safety relay from Rockwell Automation is designed to allow machine builders to implement required safety functions while improving productivity at the same time.
Users can program the safety relay through the free Connected Components Workbench Software, which allows 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.
With 22 on-board safety I/O points, including six configurable I/O, the Guardmaster 440C-CR30 safety relay is useful for applications requiring multiple safety zones. Without growing the footprint, the safety relay also can be expanded with two standard Micro800 plug-in modules to support 16 additional standard I/O points, saving valuable safety I/O points for user safety systems. The safety relay also permits interoperation with multiple standard-control platforms, enabling the safety control to remain the same even if the standard control changes.
