Time Delay Relays Multifunction ASQU / ASTU SERIES Description The ASQU and ASTU Series of 17.5 mm, knob 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. Adjustment through the time range is accomplished by an onboard knob. The ASQU Series has quick connect terminals and the ASTU Series has terminal blocks.
