The Duplexor is used in control panels where two loads are required to
alternate to provide equal run time on the loads. The alternating
action is initiated by a control switch, which is common with one side
of the control voltage. The output contacts will change states each
time the control switch is opened, thus alternating the two loads. The
LED indicators show the position of the output relay. The ARA series is
the standard Duplexor providing automatic alternating sequence. A three
position switch permits the field selection of normal duplexing action,
locking in the A-B sequence, or B-A sequence.
