Universal Switch Adjustable Interval Time Capsule ®

Model No. 438USA-INT Description:
The model 438USA-INT (Universal Switch Adjustable Interval Time Capsule) is an all Solid State timer provide Internal timing control of any load device operating from 24 to 240V AC. Timing is set via a binary coded dip switch and is adjustable from 1 to 1024 seconds. When power s applied, the 438USA-INT turns On permitting full load current to flow. At the end of the preset timing period the 438USA-INT turns Off and permits only leakage current to flow.
