ARC120AAA

The ARC/ARD Series is a duplexor that detects input of float switch inputs and determines outputs to turn on with line voltage. As the lag and lead switches open, the loads remain energized. When all switches open both loads de-energize simultaneously and the lead load alternates. The ARD series has a 3 position selector switch to lock it into normal duplexing action, 1-2 sequence or 2-1 sequence.
