Many ways of being safe
The multipurpose safety relay from ifm electronic
T
his safety relay from leading
automation supplier ifm
electronic Ltd may not look
very big, but that belies its
capabilities. The AC041S safety relay
will be very useful to many OEM’s and
end users alike, as it can be used as
either a stand-alone safety relay, or as
part of an AS-interface Safety at Work
network. It goes without saying that
the AC041S complies with the latest
safety standards, having certification to
EN 954-1/SC 4, IEC 61508 / SIL3 and
EN ISO13849-1/PLe.
As a two-channel AS-interface safety
monitor, The AC041S has more features
than it’s predecessors, not least of which
are the standard USB 2.0 interface and
a chip card to backup up settings, and
more than that are extra features built
into the safety software allowing more
functionality. The USB is for configuration
and diagnosis on a PC with the userfriendly safety software from ifm
electronic.
As a stand-alone safety relay, the
AC041S features four safe inputs or
eight standard inputs/outputs locally. It
is becoming more common with control

devices nowadays to be able to configure
a connection as input or output; the
AC041S is no exception, increasing its
versatility. The outputs are solid-state,
and can be used with relay expansion
modules also available from ifm.
When used as an AS-i safety monitor
the AC401S also processes up to four
safe inputs or eight standard inputs /
outputs locally at the same time as
monitoring up to 31 safe slaves in
the AS-i system. ifm’s user-friendly
configuration and diagnostic software
ASIMON V3.0 G2 enables clear and quick
assignment and logical combination
of the safety-related bus components
in the tried-and-tested function block
representation under Windows.
Having the chip card in a pop-out slot
in the front of the AC041S makes it
easy to save a copy of any settings;
handy for OEM’s who need to repeat
configurations, or end users who need to
keep records just in case.
In an AS-i network the AC041S AS-i
safety monitor checks code sequences
which are exchanged on the system.
If these are incorrect, or not received
in time it ensures the safe state of the
system. The unit has two safe semiconductor outputs. It is possible to
trigger up to six further safe outputs
independently in the field. The AS-i
safety monitor can be integrated into
the AS-I system at any position. Several
AS-i safety monitors can be operated via
one AS-i master. So grouping is possible
to evaluate the safe AS-i slaves without
problem.
