Safe speed & standby relay

The new MOC3SA Speed
Monitor from SICK (UK)
offers improved speed
limiting functionality on
machine tool and general
rotating machinery while
enhancing the ease of set-up
and maintenance.

Competitively priced, it
enables engineers and factory
managers to meet safety
requirements with greater
day-to-day production
flexibility and less downtime.

“SICK’s configurable
safety controller, Flexi Soft,
introduced the concept of a
simple standstill monitor,”
comments SICK (UK) safety
specialist, Iain Keetley-Smith.

“Now we are launching our
new MOC3SA Speed
Monitor as a dedicated safe
speed and standstill relay to
add further capabilities.”
A typical application for
the standstill function would
be to limit access to an area
until the machine has come
to a complete stop. Once this
has been detected a solenoid
is released from a safety gate
switch allowing access.

Safe standstill is not always
practical and in some
instances personnel need
access to the machine to
carry out setup tasks. In this
situation the machine needs
to operate at a slow speed.

Should this speed increase
for any reason the machine
needs to come to a safe stop.

The MOC3SA is simple to
setup through the use of
rotary switches and two
variants are available
depending on the frequency
being monitored.
