ATC Diversified ARA Series Duplexor Alternating Relays

ARA Duplexor Series*

The ATC Diversified ARA series duplexers are used in control panel applications where two loads are required to alternate in order to provide equal run time. The alternating action is initiated by a control switch, which is common to 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 duplexer, providing automatic alternating sequence.
