ARA Series Diversified Electronics atcdiversified.com 800.727.5646 Alternating Relays & Controllers // ARA Series The Expandable Alternating Relays are designed for use in multiple load installations that are required to alternate in sequence and have the ability to accept an additional load installation in the future. ARA-120-AME: The ARA-120-AME is a Duplexor/Triplexor Alternating Relay. With the selector switch in position A, this alternating relay will duplex the loads on terminals 7 and 9. With the switch in position B, the Alternating Relay will triplex the three loads on terminals 7, 9 and 11. For automatic alterantions, 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 alterantions, 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. ARA-120-ANE: The ARA-120-ANE is a Triplexor/Quadraplexor Alternating Relay. With the selector switch in position A, the Alternating Relay will triplex between the loads on terminals 7, 8 and 9. With the switch in position B, the Alternating relay will quadraplex the loads on terminals 7, 8, 9 and 10. For automatic alterantions, a factory installed jumper is in place between terminals 11 and 12. The alternating action is accomplished when the control switch between terminals 2 and 3 opens. For external clocking alterantions, remove the factory installed jumper between terminals 11 and 12 and place an isolated normally open switch between terminals 2 and 12. The alternating action will occur each time this isolated switch is closed and then re-opened. In the event of a power failure the Alternating Relays will return to their quiescent state and continue sequencing loads on one-at-a-time.
