Description
The model 438UPI (Potentiometer Adjustable 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 set via a
potentiometer located between the input terminals and is adjustable from 5-480 seconds.
When power is applied, the 438UPI turns "On" permitting full load current to
flow. At the end of the preset timing period the 438UPI turns "Off" and permits
only leakage current to flow through the load.
