Capable of applications using 4-10 safety circuits or up to 5 zones, this programmable relay is perfect for simple or complex applications. The Guardmaster 440C-CR30  uses Connected Components Workbench, the same programming software used for the Micro 800 family of controllers, PowerFlex Drives, and PanelView Component HMI’s, allowing the user to utilise the same programming environment for standard and safety control circuits. The software uses a drag and drop format for all of the safety inputs, outputs, monitoring circuits, and safety logic. Typical safety functions such as light curtains, safety mats, guard locking, two handed control, enabling switches, and muting can be programmed as simply as drag and dropping the icons into the program.

The Guardmaster 440C-CR30 Safety Relay comes with 22 points of safety I/O built in and allows expandability in a couple different ways. If you need additional standard I/O for reset circuits, monitoring circuits, or standard control, this can be done with utilizing the two slots on the front for Micro 800 I/O modules. The Micro 800 modules provide 4 inputs and 4 outputs for each slot. If additional safety I/O is required, there are points on the base unit that can be configured to use the “Single Wire Safety” function of the Allen-Bradley GSR safety relays.

If a visual interface is required, the Guardmaster 440C-CR30 Safety Relay on-board Modbus port allows the controller to be
connected directly to a PanelView Component HMI. This allows users to easily monitor,
troubleshoot, and modify their applications for increased productivity and uptime. If a visual interface is not required then the 5 status and 16 user programmable LED’s on the 440C’s faceplate allow the user to quickly determine faults or status of the controller locally.
