Machine builders and end-users
seeking to simplify safety relay selection and reduce component inventory and
lifecycle costs will benefit from the new family of Allen-Bradley Guardmastersafety relays from Rockwell Automation. Designed
to meet new global functional safety standards, such as EN ISO 13849-1, the new
line of safety relays includes seven basic units capable of supporting a broad
range of safety devices in a variety of applications, including single and
The new relay line features a patented, single-wire communication
capability that helps eliminate the need for dual-channel connection between
relays. Users can expand and cascade safety functions up to a SIL 3 rating using one single wire to connect
devices allowing for a reduction in installation time and effort. In addition, "AND/OR"
logic can be set via a rotary switch on the front of the relay, yielding a
variety of configurations including regional and global e-stop architectures.
A universal input feature allows devices, such as safety interlock
switches, emergency stop switches and safety mats, to use the same set of input
terminals on the relay. This helps eliminate the need to employ a specific
safety relay for a specific type of input device, helping simplify system
design and reduce hardware costs.
next generation Guardmaster safety line also features dual input modules,
providing users with twice the functionality of a standard relay in 22.5 mm
housing while reducing wiring for faster commissioning. A single TÃœV-approved
rotary switch with internal redundancy eliminates the need for double switches,
helping to speed configuration while addressing multiple functions, such as reset
modes and time delays.
A simple new chemical method for repairing and recycling notoriously difficult carbon fiber composites has been developed by the Fraunhofer Institute for Applied Polymer Research. An entire component can be completely recycled, including reclaiming its expensive carbon fibers for reuse.
In today’s connected world we are seeing the beginning of connected homes, smart grids, self-driving automobiles, drones, and many other amazing devices. Out of all the soon-to-be connected devices, which device poses the greatest dangerous to its users and society?
