Diversified Electronics ARA-120-AFE, 120 VAC Triplex Alternator
The Triplexor and Quadraplexor Alternating Relays are designed for use in multiple load installations that are required to alternate in sequence while assuring equal run time on all loads. They also allow for additional loads to run in the event of excess load requirements. The Triplexor and Quadraplexor have the option of automatic alterations or external clocking alterations. When the factory installed jumper is in place the alternating action is initiated by a control switch, which is common with one side of the control voltage. When the jumper is removed the alternating action is initiated by an isolated normally open switch. ARA-XXX-AFE Alternating Action. Triplexor: For automatic alterations a factory-installed jumper is in place between terminals 3 and 4. The alternating action is accomplished when the control switch between terminals 2 and 4 opens. For external clocking alterations, remove the factory-installed jumper between terminals 3 and 4 and place an isolated normally open switch between terminals 2 and 3. The alternating action will occur each time this isolated switch is closed and then re-opened.
