| 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. |
