Aproviding interval timing control of a load device operating
from DC voltage and switching up to ten amperes of DC load current. The
interval timing period is adjustable from 1 to 1024 seconds in increments
of 1 second. When DC voltage is applied, the 438USA-PIN turns on
permitting full load current to flow. At the end of the preset timing period the
438USA-PIN turns off and permits only leakage current to flow through the load To repeat a
cycle, the operating voltage must be removed for at least 100 milliseconds.
The model 438USA-PIN Switch Adjustable Interval Time Capsule is an all solid state timer
