Description

 

The model 438USAS (Universal Switch Adjustable Time Capsule) is an all Solid State timer providing Delay on Make control to any load operating from 19 to 288V AC or DC. Timing is set via a binary coded dip switch and is adjustable from 1-1024 seconds. When power is applied, the 438USAS remains in the off state. When the preset time period has elapsed, the 438USAS switches on allowing the load to energize. The load remains energized as long as power is applied
