Amperite Co. Time Delay Relay, Spst-No, 2A, 20-28Vdc; Relay Mounting Amperite 24D30MSTB

The Amperite STB Series is a solid-state triggered delay-on-release relay with CMOS digital timing circuitry, offering fixed or field-adjustable delays from 0.1 seconds to 100 hours. It features a 2-ampere continuous load current rating, a voltage drop of 2.5 volts RMS or less at full current, and a 20-ampere maximum inrush capability. The device operates on 24-volt DC input, with an input voltage range of 20 to 28 volts. Enclosed in a 2 x 2 x 0.75-inch black plastic case with epoxy sealing and center hole mounting, it includes four or six 1/4-inch quick-connect terminals. Timing is set via an external resistor or potentiometer, with a tolerance of ±10% for fixed units and repeatability of 2%.
