Box 329 West New York, NJ 07093 (800) 752-2329 www.Amperite.com … 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. Timing Diagram: 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. Environmental Information: Temperature Range: -40° C to +65° C (-40° F to +149° F) Timing Specifications: Timing: Factory fixed, or .1 seconds to 100 hours in any one of eight ranges.

For other voltages consult factory. B: Denotes type of input power required for operation A = AC - Alternate Current D = DC - Direct Current C&D: Denotes range of adjustability 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 ST1 Series solid state, normally open time delay. Solving Your Relay Requirements Since 1922
