Overview

The Macromatic AE1U2R is a duplex alternating relay. It shares run time evenly between two loads, typically pumps, compressors or fans, so neither one wears out first and the spare is proven every cycle. A single control switch, such as a float or pressure switch, runs it. Each time the switch closes, the load whose turn it is runs; when the switch opens, the relay toggles so the other load runs next time. The slim 17.5 mm case snaps onto 35 mm DIN rail (no screw panel mounting), takes universal control voltage (24-240 V AC and 12-240 V DC), and is cULus listed. LEDs show power and which load is next. A selector switch chooses normal alternation or locks either load to run first, which is handy while one pump is out for service. The 10A DPDT output is rated 10A at 250V AC / 8A at 30V DC. Mechanical life is 10 million operations (100,000 at full load). Typical uses are duplex pump panels, lift stations, and compressor and HVAC staging.
