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. Features & Benefits Universal AC or DC voltage Choose from 24 to 240VAC or 9 to 110VDC models Compact 17.5mm size Allows for high rail density Microcontroller based Repeat Accuracy + / -1% Multifunction: 5 timing functions Reduce stocking requirements Knob Adjustable Time Delay Field adjustable delay ranging from 0.1s - 100m 0.7A steady, 10A inrush solid-state output Provides 100 million operations in typical conditions. Mounting fasteners included Each unit ships with both surface and DIN rail quick mount adapters Watchdog circuitry Self monitoring and self correcting for improved performance Specifications Time Delay Type Microcontroller based with ceramic resonator and watchdog circuitry Adjustment 6 switches adjust the time delay;2 switches select 1 of 4 multipliers Range* *For CE approved applications, power must be removed from the unit when a switch position is changed. x0.1s = 0.1 - 6.3s in 0.1s incrementsx1s = 1 - 63s in 1s incrementsx10s = 10 - 630s in 10s incrementsx1m = 1 - 63m in 1m increments Repeat Accuracy ±0.1% or ±20ms, whichever is greater Setting Accuracy ±2% or ±50ms, whichever is greater Reset Time ≤ 300ms Initiate Time Single Shot & Delay-on-Break: ≤ 32ms Time Delay vs Temp. & Voltage ±2% or ±50ms, whichever is greater Input Voltage AC: 24 to 240VAC; -20% - 10%DC: 9 to 110VDC; -0% - 20% @ -25°C9.4 to 110VDC; -0% - 20% @ -40°C AC Line Frequency/DC Ripple 50/60Hz / ≤ 10% Output Type Solid state Form NO Rating 0.7A steady state, 10A inrush Voltage Drop AC ≅ 2.5V @ 0.7A; DC ≅ 1.5V @ 0.7A Protection Surge IEEE C62.41-1991 Level A Circuitry Encapsulated Dielectric Breakdown ≥ 2000V RMS terminals to mounting surface Polarity DC units are reverse polarity protected Mechanical Mounting Two base adaptors are available DIN Rail Snap on to 32 mm DIN 1 & 35 mm DIN 3 rail Surface Two #6 (M3.5 x 0.6) screws or quick mount fasteners Dimensions H 76.2 mm (3.0”)W 17.52 mm (0.69”)D 61.2 mm (2.41”) Termination DSQU 0.25 in.
