The 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 a single wire to connect devices, reducing 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. The line also features dual input modules, providing users with
twice the functionality of a standard relay in a 22.5mm housing, while
reducing wiring for faster commissioning.Rockwell Automation Inc.www.ab.com/safety800.227.6143
