The model 438USAI (Universal Switch Adjustable Interval Time Capsule) is an all Solid State In-Line timing device providing Interval timing control of any load device operating from 24 to 240V
AC or DC. Timing is set via a binary coded dip switch and is adjustable from 1-1024 seconds. When power is applied, the 438USAI turns "On" permitting full load current to flow. At the end of
the preset timing period the 438USAI turns "Off" and permits only leakage current to flow through the load.
