Fixed Interval Time Capsule ®

Model No. 438FI 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.
