The two new Allen-Bradley
safety relays from Rockwell
Automation promise to
deliver high-performance safety
protection while helping OEMs
reduce installation time and costs.
These two safety relays from
Rockwell Automation have been
designed to conserve panel space
and reduce wiring complexity.
Offering broad application
versatility and a modular, easily
expandable design, the new
MSR142RTP and MSR144RTP relays
are the latest additions to the
Allen-Bradley GuardMaster family
of safety relays from Rockwell
Automation. "Traditionally, users
have had to choose between safety
and flexibility. These new safety
relays - with their modular design
and reliable performance - put to
rest this assumption," said Kevin
Zomchek, Product Manager,
Rockwell Automation.
Featuring seven safety outputs,
four auxiliary outputs and two
solid-state auxiliary outputs, the
MSR142RTP multi-output relay is
designed to meet a variety of
application requirements,
including safety switches, light
curtains and safety mats. The
MSR142RTP is housed in a 67.5
mm-wide DIN-rail mount with
removable terminals and accepts
both solid state and electromechanical
inputs. Moreover,
the relay is equipped with
automatic or monitored manual
reset capabilities. "The MSR142
helps users reduce installation
costs and conserve cabinet space
by allowing them to switch up to
seven outputs without having to
buy additional expansion
modules," said Mr Zomchek.
The second new relay, the
MSR144RTP, can be connected in
four different input wiring
configurations and is easily
expanded via a ribbon connector
from the dedicated expansion
modules. Up to five modules can
be connected together in any
combination of immediate or
delayed output modules. The relay
allows users to switch several
safety circuits or different voltages
with one E-stop command.
"The MSR144RTP safety relay,
when combined with plug-in
output expansion modules, is ideal
for complex applications where
flexibility and a high number of
output contacts are required," Mr
Zomchek added. In addition to
reducing installation costs and
wiring complexity, the MSR144RTP
helps simplify inventory, as its
modular design can be applied to
meet a broad range of equipment
specifications and application
demands.With removable coded
terminals and extended LED
diagnostics, the relay not only
provides a high level of safety
protection, but also helps reduce
service and maintenance costs.
The MSR144RTP conforms to
standards EN 954-1, ISO 13849-1,
IEC/EN 60204-1, AS4024.1 and
ISOTR12100, and is CE marked for
all applicable directives: TUV and
cULus. The unit is encased in a
IP40-rated, Polyamide PA 6.6
housing, which protects against
shock and vibration, and offers
users convenient 35 mm DIN rail
mounting capabilities.
