Alternating Relay 120VAC DPDTCross-Wired MPN:ARP120A3R

Alternating Relays with DPDT cross-wired outputs are used in applications requiring both (a) the optimization of load usage by equalizing the run time of two loads and (b) additional capacity in case of excess load requirements. This alternating action is initiated by a control switch, such as a ?oat switch, pressure switch, or other isolated contact. Each time the initiating switch is opened, the output relay contacts will change state, thus alternating the two loads. Two LEDs indicate which load will energize ?rst. These products are typically used to control two loads when the need to have both loads on at the same time for additional capacity is required. However, they can be used with only one input device—simply wiring the single input device where the “LEAD” input is shown on the wiring diagram and disregard the second input, or “LAG” switch. A three-position selector switch is offered. This allows a DPDT cross-wired unit to alternate the two loads as normal, or lock the relay to always operate the same load ?rst each time. A load that has fewer hours of operation than the other load could be used more often to eventually balance the run time of both loads. The selector switch has a low-pro?le to prevent any accidental changes in status.
