Macromatic Industrial Controls, Inc. Duplex Alternating Relays - ARP Series ARP024A3R

Duplex Alternating Relays are used in special applications where the optimization of load usage is required by equalizing the run time of two loads. This alternating action is initiated by a control switch, such as a float switch, manual switch&, timing relay, 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 LED indicators show the status of the output relay.

Cross-wired alternating relays are also used where additional capacity is required in case of excess load requirements. Not only will this version alternate between two loads, but it also allows both loads to run simultaneously when the lead and lag switches are closed, thus providing a way for both loads to operate when running just one does not provide enough capacity.

Duplex Alternating Relays are available in three output configurations: SPDT, DPDT and DPDT cross-wired. See KnowledgeBase Article for more information.

Each version is available with an optional three position selector switch. This allows the unit to alternate the two loads as normal, or lock the relay to one load or the other. By locking the Alternating Relay to one load, the other load can be removed for service without rewiring the first load for continuous operation. In addition, on cross-wired versions, locking a load to always operate first allows the user to balance the run time of both loads if one load has fewer hours of operation than the other. The selector switch has a low profile to prevent any accidental changes in status.

Alternating Relays are used in special applications where the optimization of load usage is required by equalizing the run time of two loads. Each time an initiating switch is opened, the output relay contacts will change state, thus alternating the two loads.
