Allen-Bradley Guardmaster 440C-CR30
Software Programmable Safety Relay
Looking for a logic solution for small to mid-range safety applications? Look no further than the new 440C-
CR30 programmable safety relay from Allen-Bradley. This new programmable relay ts in the space between
standard/special purpose safety relays and a GuardLogix solution. Capable of applications using 4-10 safety
circuits or up to 5 zones, this programmable relay is perfect for simple to somewhat complex applications.
Using Connected Components Workbench, the same programming software used for the Micro 800 family
of controllers, PowerFlex Drives, and PanelView Component HMI’s, the user can utilize the same program-
ming 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 hand control (anti-tie down), enabling switches, and muting can be
programmed as simply as dragging and dropping the icons into the program.
The programmable 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 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 congured to use the “Single Wire
Safety” function of the Allen-Bradley GSR safety relays.
If a visual interface is required, the 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 uptime. If visualization is not required but status and troubleshooting help is,
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
all locally.
