438A-12-1產(chǎn)品概述
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.
