Time Delay Relays Multifunction DSQU / DSTU SERIES Description The DSQU and DSTU Series of 17.5 mm, switch adjustable, universal solid-state timers offer multiple functions, voltages, and time delay ranges. Choose one of 5 functions and 4 time delay ranges via 4 selection switches located on face of the unit. Six switches adjust the time delay through the selected range. The DSQU Series has quick connect terminals and the DSTU Series has terminal blocks.
