ST1 Series Solid State Delay-On-Make Timers

  • 100% solid state circuitry-no moving parts
  • Two terminal series connection to load
  • Fixed or field adjustable delays from milliseconds to hours
  • UP to 1 ampere continuous load current
  • CMOS digital circuitry
  • UL File #E96739 (M)
  • CSA File #LR62586

Timing Mode: Delay on operate begins upon application of input power. The load is energized at the end of the delay period and remains so until input power is removed

Contact Information: Solid state switching device 1 form A, normally open series connection. Continuous current rating 1 ampere. Maximum inrush 10 amperes. Minimum load current 5 milliamperes. Voltage drop typically 2.5 volts RMS @ 1 ampere.

Timing Specifications:

  • Timing: Factory fixed, or 0.1 seconds to 100 hours. Timing is set by user supplied resistor or potentiometer. Custom timing available.
  • Timing ranges:

.1 to 10 seconds 1 to 100 minutes

.2 to 20 seconds 10 to 1000 minutes

1 to 100 seconds .1 to 10 hours

10 to 1000 seconds 1 to 100 hours

.1 to 10 minutes

  • Timing tolerance: fixed units = +/- 10%
  • Timing repeatability: +/- 2%
  • Timing cycle interrupt transfer: none

Mechanical Information: Enclosure 2 x 2 x 3/4 inch black plastic, epoxy sealed. Center hole mounting. Two or four 1/4 inch quick connect male terminals.
