Description
The model 438FI (Fixed Interval Time Capsule) is an all Solid State In-Line timing
device providing Interval timing 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.
