Macromatic ARP240A3R Alternating Relay with First-Load Selector
Combines two-load alternating control with LED first-load indication and a selector switch that can hold the same load in the lead position.
Two-Load Alternation with Added Load Capacity
The ARP240A3R is used where two loads must alternate and additional load capacity is needed. Its duplexor function changes the lead load through normal cycling rather than leaving one load permanently favored.
🔄 Automatic Load Alternation
A control switch starts the alternating action. When the initiating switch opens, the output contacts change state so the connected loads alternate.
💡 First-Load LEDs with Lead-Load Override
Two LEDs indicate which load energizes first. The low-profile selector switch can lock the relay into one load so the same load runs first, which can help correct uneven usage if one load has been favored.
