Description
The model 438UI (Universal Interval Time Capsule) is an all Solid State In-Line timing
device providing Interval timing control of any
load device operating from 19 to 288V AC or DC. Timing is set via a remote resistor
ranging from zero to 10 Meg Ohms to achieve an interval of 1-1000 seconds. When power is
applied, the 438UI turns "On" permitting full load current to flow. At the end
of the preset timing period the 438UI turns "Off" and permits only leakage
current to flow through the load.
