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 TÃV-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 Tokyo company, Miraisens Inc., has unveiled a device that allows users to move virtual 3D objects around and "feel" them via a vibration sensor. The device has many applications within the gaming, medical, and 3D-printing industries.
In the last few years, use of CFD in building design has increased manifolds. Computational
fluid dynamics is effective in analyzing the flow and thermal properties of air within spaces. It can be used in buildings to find the best measures for comfortable temperature at low energy use.
