ARB and ARA Spec Sheet
 

RELAY OVERVIEW

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.  LED indicators show the position of the output relay.

The ARA series is the standard Duplexor providing automatic alternating sequence.  The ARB has the automatic alternating feature plus the option of locking it into one mode.  A three position switch permits the field selection of normal duplexing action, locking in the A-B sequence, or B-A sequence.
