| 356C Series Shawnee II Digital Counter |
| Series Description: A compact version of the 336 counter, the ATC 356 is its exact functional duplicate. Packaged in a 72mm2 DIN-size housing, it occupies 40% less panel space and costs proportionately less. Modern production and assembly techniques have all but eliminated hand wiring, enhancing the reliability and life expectancy of the 356. FAST, ACCURATE AND BOUNCE-PROOF: The repeat accuracy of the 356 is 100%. It maintains full accuracy even at pulse rates up to 4,000/minute, even with pulses that are as brief as 1 millisecond, and even in the face of severe contact bounce, which it ignores by virtue of an extremely effective anti-bounce circuit. |
| Series Operation: The Shawnee 356 operates on a digital logic circuit with three main elements: a pulse circuit; a read-only-memory (ROM) whose output is set by the counters digital setting number wheels; and a comparator that continuously examines the outputs of the pulse circuit and ROM. When power is applied (start signal on), two things happen simultaneously; the instantaneous DPDT relay is energized transferring both sets of contacts, and the pulse circuit begins to count each input pulse whose duration is at least 1 millisecond. The pulse circuit accumulates the count and feeds the total continuously to the comparator. When pulse circuit output exactly equals the output of the ROM, the comparator causes the 356 to count out. At this point, (1) the DPDT delay relay is energized, immediately transferring both sets of contacts and (2) the pulse circuit turns itself off automatically. Since the pulse circuit stops counting even if the start signal remains on, it is not necessary to tie up one of the 356s delayed contacts to do this job. To reset the 356, power must be removed from terminal 1 (L1) for 75 milliseconds or more. The 356 operates in the on-delay mode only, always resetting whenever there is a power outage and starting a new cycle when power is restored. |
