Through advanced circuit design and packaging technology, the ON-

Delay ATC 313 packs all of the performance of a conventional plug-in

TDR in a space-saving housing. It features a digital timing circuit which

ensures high repeat accuracy and excellent noise immunity.

MINIATURE HOUSING: You can mount several ATC 313 timers in the

same space as a single conventional TDR.

DIGITAL ACCURACY: A custom C-MOS integrated circuit accurately

measures the dial-adjustable delay by counting the output of an internal

oscillator. Repeat accuracy remains high even with variations in voltage,

temperature and reset time.

STATUS INDICATORS: Two LEDs clearly indicate the operational status

of the 313: one is energized when power is applied; the other is off dur-

ing the delay period and on at time-out.

INDUSTRIAL QUALITY: With a load relay capable of switching 7A resis-

tive loads and a C-MOS design that protects components against noise

and voltage transients, the 313 is built for industrial use.
