Solving your relay requirements since 1922 ST2 Series Solid State Interval (One-Shot) Timer Amperite Co. 567 52nd Street P.O. Box 329 West New York, NJ 07093 (800) 752-2329 www.Amperite.com … 100% solid state circuitry - no moving parts … CMOS digital timing circuitry … Fixed or field adjustable delays from milliseconds to hours … 2 amperes continuous load current (10 amperes available, consult factory) … UL File # Pending … CSA File #Pending Timing Mode: Upon application of power the load is energized and the time delay cycle is initiated. At the end of the delay time the load is de-energized. Reset is accomplished by removing input power. Timing Diagram: Contact Information: Solid state switching device 1 form A; normally open series connection. Continuous current rating 2 amperes. Maximum inrush 20 amperes. Voltage drop 2.5 volts RMS or less @ 2 amperes. (For 10 ampere load current rating consult factory) Timing Specifications: Timing: Factory fixed, or .1 seconds to 100 hours in any of the ranges below. Timing is set by user supplied resistor or potentiometer. Custom timing available. Solving your relay requirements since 1922 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 Outline Dimensions: AC (60 Hz) and DC Input Voltages & Limits Nominal Minimum Maximum 12V 10V 14V 24V 20V 28V 48V 41V 55V 110V 95V 125V 120V 105V 130V 230V 190V 255V Amperite Co. 567 52nd Street P.O.

B: Denotes type of input power required for operation: A = AC - Alternating Current; D = DC - Direct Current. C & D: Denotes range of adjustability by using an external resistor or potentiometer, where C is the minimum timing and D is the maximum timing. Standard timing span is 100:1. For fixed timing units specify a single number. E: Denotes unit of time delay: S=seconds; M=minutes; H=hours. F: Denotes Amperite ST2 Series solid state, normally open time delay.
