Alternating Relay and Duplex Controllers manage pump runtimes.
Rugged ARM Series microprocessor-based controllers evenly distribute runtime by automatically alternating lead and lag loads between 2 pump sequences. Devices include inrush delay to prevent both loads from energizing simultaneously, and five UL913 intrinsically safe low-voltage/-current control switch inputs. Integral device logic allows outputs to function if one input fails to open or close,...
