The Series DPC is designed for use where two pumps are required to alternate to provide equal runtime on each. The 120-Vac-controlled relay alternates each time a control switch opens. Two LED indicators show the load that is energized by an SPDT output relay. Model DPC-ACS provides an automatic alternating sequence, while the DPC-ALS also offers an A-B or B-A sequence lock selectable by a three-position toggle switch.
