These machine safety products can help engineers right-size their safety systems while optimizing machine productivity, footprint and cost — avoiding both under-designed systems that can put workers in danger and result in big expenses and over-designed systems that use more safety devices than required and can lead to unnecessarily complex and expensive machines. The newly expanded Allen-Bradley Compact GuardLogix 5380 controller family can now meet SIL 2/PLd to SIL 3/PLe safety requirements. New safety modules for the FLEX 5000 and Compact 5000 I/O product families improve safety response times, allowing engineers to move guarding devices closer to machines to reduce machine footprints. The safety modules are TÜV certified for use in safety applications up to SIL CL 3, PLe, Cat. 4. The PowerFlex 755 and 755T AC drives offer a new Integrated Safety Functions Option Module, providing several safety functions based on IEC 61800-5-2 standards. The module monitors speed, direction and position, and integrates safety and standard control systems on a single EtherNet/IP network using one controller. In addition, the networked safety solution provides zone control in which one zone of the machine is brought to a safe state while other zones continue to operate.
