Knob Adjustable Universal Timer
ASQU/ASTU MicroTime
Timing Module
Description
The ASQU/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 top of the unit. Adjustment through the time range is accomplished by an onboard knob.
