Allen-Bradley Guardmaster 440C-CR30 configurable safety relay

The Allen-Bradley Guardmaster 440C-CR30 is a flexible, cost-effective and easy-to-use configurable safety relay suitable for applications requiring 4-10 safety circuits and control of up to five zones. The Guardmaster 440C-CR30 is configured through Connected Components Workbench (CCW) software - the same programming environment used by the Micro 800 family of controllers, PanelView component HMIs and PowerFlex drives.

The distinct graphical user interface and drag-and-drop capabilities of CCW help guide users through a simple process of selecting certified safety function blocks for the 440C-CR30. This means users can create, control and monitor a safety system in the same software environment as their standard control, resulting in increased productivity and reduced programming time.

An embedded Modbus interface allows the Guardmaster 440C-CR30 to communicate diagnostic data to an Allen-Bradley Micro 800 PLC and PanelView component. By leveraging the features of CCW and the embedded communication capabilities of the Guardmaster 440C-CR30, users can monitor, troubleshoot and modify their applications quickly and easily for increased uptime. Five status and 16 user-configurable LEDs on the Guardmaster 440C-CR30 relay’s faceplate provide local diagnostics to further aid in status reporting and troubleshooting.

The Guardmaster 440C-CR30 helps optimise panel space with 22 onboard configurable safety I/O points in a 110 mm footprint and provides a flexible solution for applications requiring multiple safety zones. Without increasing the footprint, the 440C-CR30 can also be expanded with two standard Micro 800 plug-in modules to support 16 additional standard I/O points.
