Shawnee II Digital Counter

A compact version of the 336 counter, the ATC 356 is its exact func-

tional duplicate. Packaged in a 72mm2 DIN-size housing, it occupies

40% less panel space and costs proportionately less. Modern pro-

duction 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.

EASY TO SET AT ALL TIMES: The Shawnee counter is easily and

accurately set even with work gloves on. Push any of its four toggle

levers in any sequence until the number you want appears above it.

You can decrease as well as increase each number by pushing the

levers up or down. You can change the setting at any time, even dur-

ing a cycle.

PLUG-IN AND DUST-TIGHT: All 356 counters feature true plug-in

design and can be replaced in seconds without disturbing the housing

or disconnecting the wiring. The dial assembly is gasketed so that the

counter body is dust-tight from the front of panel.

CYCLE PROGRESS INDICATION: The Shawnee 356 indicating counter

provides cycle progress indication on the four-digit display located

immediately above the digital setting number wheels. When the

counter is in the reset condition, the VFD display is blank. During

the cycle, the display counts up from 0, thus always indicating the

number of counts that have elapsed since the start of cycle. At count-

out, the display shows the total elapsed count and thus equals the

numbers on the digital setting wheels.

COMPUTER-TESTED RELIABILITY: The solid-state 356 is manufac-

tured from a series of computer-tested plug-in circuit boards and as-

sembled virtually without hand wiring. Because it has no moving parts

in its logic circuits, its life expectancy is practically unlimited. Even the

load relay – the 356’s only significant mechanical component – has a

life expectancy of 10,000,000 operations (no load). As a result the

356 achieves an overall reliability that surpasses even that achieved

by previous Shawnee counters.

NOISE IMMUNITY: The 356 does not have to be shielded: its trans-

former power supply, full-wave bridges, buffered logic and other

design characteristics render it immune to the electrical noise that is

sometimes encountered in industrial environments thus eliminating

false starts and reset due to voltage spikes.

The 356C Directly Replaces 356B & 356A.

SAVE 40% IN PANEL SPACE AND COST: Packaged in a 72mm2 DIN-

size housing, the 356 occupies 40% less panel space than previous IC

timers. Modern production and assembly techniques have substantially

reduced manufacturing costs resulted in a 45% cost saving.

LOW INVENTORY COSTS: Each Shawnee 356 covers the active count

range of 1 to 9,999, easily satisfying the vast majority of industrial

requirements and thus greatly reducing inventory.
