Description:Delay on Make • Time Delay Relay • Input Voltage : 230 VAC/VDC • Timing Range: 1 - 60 sec • Mounting : Base Mount • Contact Configuration: NO • Output Current: 1 Amp
Delay-On-Make, external load energizes after preset timing period.
Adjustable Timing Ranges
Five (5) models of adjustable delay-on-make timing from 0.1 seconds to 1800 seconds.
Timing Range Accuracy
Minimum time -15%, +0%. Maximum time -0%, +20%
Timing Variation
Less than 6% of set point over full temperature and voltage range.
Repeatability Of Timing Period
±1% at stabilized operating voltage & temperature.
Recycle Time
Operating voltage must be removed for a minimum of 50mS after timing period, 200 milliseconds during timing period to assure new cycle repeats to full time delay period.
Output Rating
10mA to 1A inductive with inrush current to 25A for 8 milliseconds.
Output Switch Characteristics
4 volt drop across output switch when ON, 3mA leakage when OFF.
Transient Protection
Protected by silicon transient suppressors responding to transients within 1 x 10-12 seconds to a peak pulse power dissipation of 1500 watts, with transient surge currents to 200 amperes for durations up to 1/120 second at 25° C. Maximum transient voltage protection is 6000 volts as delivered through a source resistance of 30 ohms with a maximum duration of 8.3ms.

Encapsulated module with .25 quick connect wiring terminals.
Series Features
Model No. 438APS Potentiometer Adjustable Delay On Make Timer
Series Description:The mode 438APS (Adjustable Pot Time Capsule) is an all Solid State timer providing Delay on Make control to any load operating from specified operating voltages. The timer is wired in series with the load without concern for polarity. When power is applied, the 438APS remains in the off state. After the preset period has elapsed the timer switches on energizing the load. The timing period is controlled by a potentiometer wired internally, providing a method by which to panel mount the timer.
