438

Delay-On-Make

Time Capsule®

The Model 438 delay-on-make is another member of the Artisan Controls

Corporation family of Time Capsules®. To use the model 438 connect the outer

two terminals in series with any load circuit that draws between ten milliamperes

and one ampere. Connect to the specified operating voltage between 12 and

240 volts either AC or DC. Connect the proper timing resistor across the center

two terminals (on adjustable models) and apply operating voltage. When the

operating voltage is applied a small amount of current will flow through the load

and the timer. At the end of the delay period, the model 438 turns ON and full

load current is permitted to flow. To recycle, remove the operating voltage for at

least 50 milliseconds.

How The Chart Works. . . . . . .

The -2 range indicates a timing range of 1 to 30 seconds when the external

timing resistance varies from 0 to 1 meg ohm. The -2 extended range of 300

seconds can be achieved by using a 0 to 10 meg ohm external resistance.
