Available timing functions include “A” & “At” delay on make, “B” single shot, “C” delay on break, “H” & “Ht” interval, “L” & “Li” repeat cycle, and “U” multifunction that includes A, At, Ac, B, Bw, C, D, Di, H, and Ht functions. Basic timing function selection is user settable via screw slot rotary switches on the side of the SeriesOne DR Timers, while unit and fine timing adjustments are made on the front panel of the Timers. This arrangement provides easy access to Technicians for simple timing adjustments but significantly reduces accidental changes to the basic function.
Control for the SeriesOne DR Timers, depending on model, is 12 to 24 VAC/DC for all models, with options of either 90 to 140 VAC or 180 to 240 VAC for AC outputs only. All Crydom SeriesOne DR Timers are UL listed and cUL recognized, UL Motor Control rated, RoHS and China RoHS compliant, and CE certified to the Low Voltage and EMC Directives.
