Safety relays for universal use

Wieland Electric’s new range
of safety relays are only
22.5mm wide and have been
designed for universal use.

The SNO 4083KM relays are
suitable for most mechanical
engineering applications,
particularly special machine
engineering or for smaller
serial machines.

Their safety functions
range from conventional
emergency stop and safety
door monitoring and
monitoring of electrosensitive
protective
equipment (ESPE) – type 4
(safety light curtain) – to the
monitoring of pressure mats
or coded magnet switches
with open/close contact
pairs.

Additional functions
include a selective automatic
or manual monitored restart
of the safety function,
synchronous time
monitoring of 0.5 or 1.5
seconds for all two-channel
applications, and the
integrated Monoflop
function for higher device
availability.

The smart diagnosis of the
device operating state helps
reduce downtime and
supports economical
machine operation, as well as
the high operating capacity
of the contacts and the wide
temperature operating range
of -25 ºC to 65 ºC. The
SNO 4083KM safety relays
are used for conventional
safety tasks in mechanical
and system engineering and
applications in lift
engineering (according to
EN 81-1) or in controls for
industrial combustion plants
(according to EN 50156-1).
