Littelfuse DSQUD3, DSQU / DSTU Series, 9-110VDC, Programmable (Multi-Function) Time Delay Relay SPST-NO (1 Form A) 0.1 Sec ~ 63 Min Delay Chassis Mount
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.
