Macromatic ARP240A2R Alternating Relay with Manual Load Selection
Built for two-load run-time equalization with LED next-load indication plus a selector switch that can hold operation on one load when balancing is needed.
Balance Operating Time Across Two Loads
The ARP240A2R is a duplexor relay for applications where two loads need their run time equalized. Normal operation alternates the loads so one unit is not consistently used more than the other.
🔄 Automatic Alternation from the Control Switch
A control switch initiates the alternating action. When the initiating switch opens, the output contacts change state so the loads alternate as the sequence continues.
💡 Next-Load LEDs with Selector Override
Two LEDs indicate which load energizes next. The low-profile selector switch can lock the relay into one load so only that load remains energized, allowing additional run time to be assigned when one load has been used less than the other.
