The model 438FI (Fixed Interval Time Capsule) is an all Solid State In-Line timing device providing control of any load device operating from 115 or 230V AC or DC. Timing is factory fixed from
250 milliseconds to 1000 seconds. When power is applied, the 438FI turns "On" permitting full load current to flow. At the end of the preset timing period the 438FI turns "Off" and permits only
leakage current to flow through the load. Then interval timing action can be repeated by removing and re-applying the operating voltage.
