High-performance, safe
coupling relays just 6mm wide
he new PSRmini safety
modules from Phoenix
Contact are the world’s
slimmest safety relays with
the power of a large safety
relay. With their compact 6-mm width,
they ensure high safety thanks to
positively driven contacts. For users,
these slim modules require up to 70
percent less space.

A comprehensive package of tests
and approvals ensures that the
modules can also be flexibly used in
applications and environments that
exceed the norm. For example, the
relays are G3-compliant according to
ISA S71.04-1985 for use in especially
corrosive atmospheres and are IECExcertified, thereby facilitating the

down to Ex Zone 2. Repeat tests in a
process plant, which are prescribed
by standards, can easily be performed
visually and directly on the device.
Complex manual measurements that
are currently required when using
standard relays that are not forcibly
guided according to EN 50205 are
therefore often unnecessary. In
addition, in some common control
systems, monitoring of the controls of
the coupling module may be influenced
in the event of an error, so that the
repeat test, the so-called proof test,
can be designed to be almost fully
automated. This increases efficiency
since downtime can be reduced without
necessitating additional effort for
required hardware or installation.
The compact design of the safety
modules is made possible through
Phoenix Contact’s newly developed
relay technology. The design is based
on a slim, powerful, and force-
guided basic relay characterized by
minimal space requirements, low
energy consumption, and high system
availability. Despite its compact width
of just 6 mm, the component features
