Universal Interval Time Capsule ®

Model No. 438UI 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.
