Rockwell Automation’s New Safety Modules Help to Simplify Integrating Safety into Machines

Company and Product News

Rockwell Automation announced the introduction of seven new safety modules across three I/O platforms, offering machine designers both local and distributed safety I/O options and a range of performance and connectivity attributes to help improve compliance and machine performance.  Machine designers are required to design safety into an increasing number of industrial systems, and need solutions to help ease the design process and meet other application requirements. The new safety modules also help to simplify the design process by having, for example, a largely common data structure and graphic user interface.  This programming and operation can also help to reduce design time, allow for code reuse, and shorten the learning curve for designers.

The new safety I/O modules include:

  • The Allen-Bradley Compact 5000 safety I/O modules provide local and distributed safety I/O for the Compact GuardLogix 5380 safety controller and distributed safety I/O for the GuardLogix 5580 safety controller.  These modules offer faster safety reaction times to help machine designers lower their costs and create smaller and simpler machines.  They also provide additional diagnostics to help users more easily identify faults.
  • The Allen-Bradley ControlLogix CIP Safety I/O modules provide local safety I/O for the GuardLogix 5580 controllers in larger applications that require a high-density I/O solution.  Using these in-chassis modules helps to simplify configuration and reduce panel space by eliminating the need for an adapter.  These modules can also be used for distributed safety I/O.
  • The Allen-Bradley FLEX 5000 safety I/O modules are for applications that require fixed field-wiring terminations and both vertical or horizontal mounting.  These distributed I/O modules can operate in more extreme environments and be used by directly connecting to copper and fiber networks.  They also support a range of network topologies, including a redundant star network via Parallel Redundancy Protocol, and further enhance communications with 1-gigabit EtherNet/IP connectivity.  The FLEX 5000 platform provides distributed safety I/O for the Compact GuardLogix 5380 and GuardLogix 5580 controllers.

Each of the seven new safety I/O modules is TÜV certified for use in safety applications up to SIL 3 and PLe, Cat. 4.  For added protection against environmental stresses, all modules are selectable with conformal coating options.
