AR/ARD Series—Convertible Contact Industrial Control
Product Description
The AR/ARD relays are
electromechanical convertible
contact relays. AR relays are
AC devices and the ARD is
for DC applications.
Application Description
Type AR and ARD relays are
designed for use on machine
tools, process lines,
conveyors and similar
automatic and semi-
automatic equipment.
Features and Benefits
Permanent Magnet Latch
By energizing the relay coil,
the latch attachment “sets”
(when the base relay’s
armature/crossbar assembly
has closed) holding the relay
ON, even after the relay coil
has been de-energized. The
clearing coil on the latch is
energized to release the
armature/crossbar assembly.
●
Field mountable to four-
and six-pole
●
Latch plunger is adjustable
●
Latch coil continuously
rated

Operation
AR relays are available in
either
four- or six-pole
configurations.
AR relays are
easily converted
to eight- or
10-poles simply by adding a
four-pole deck. In addition,
mechanical latch attachments
are available with four- and
six-pole relays.
Contacts are convertible from
NO to NC, to provide any
combination desired up to a
maximum of 10. For the ARD,
the number of poles cannot
exceed four NC in any pole
configuration. Wide spacing
of contacts simplifies
installation, contact testing and
maintenance. Contacts are
electrically and mechanically
isolated from each other.
Overlap contacts are also
available in one or two sets.
These contacts should be
mounted in the center pole
positions. AC and DC contact
cartridges should not be used
in the same relay.
