The Model 438API is an in-line timing device that performs as a two terminal
interval timer suitable for panel mounting. Operation is exactly the reverse of
the standard Artisan Controls Corporation's 438AP Time Capsule ?. When
connected in series with a load circuit, the 438API will energize the load when
operating voltage is first applied, turning off after the externally set interval time
delay period. The interval timing periods is controlled by an internal adjustment
potentiometer. Eleven models provide interval timing from 0.1 to 300 seconds.
The interval timing action can be repeated by removing and re-applying the
operating voltage. The 438API operates on either 115V or 230V AC or DC, and
operates a load circuit up to .25 amperes.
