Shawnee II Digital Reset Timer

A compact version of the 335 Timer, the ATC 355 is its exact func-

tional 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 355.

COMPUTER TESTED RELIABILITY: The Solid-State 355 is manufac-

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

assembled 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 355’s only significant mechanical compo-

nent — has a life expectancy of 100,000,000 operations (no load).

As a result, the 355 achieves an overall reliability that surpasses

even the high level achieved by previous Shawnee timers.

CYCLE PROGRESS INDICATION: The Shawnee indicating timer

provides cycle progress indication on a four-digit display located

immediately above the digital setting number wheels.

PLUG-IN AND DUST-TIGHT: All 355 timers feature true plug-in de-

sign and can be replaced in seconds without disturbing the housing

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

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

WIDE RANGE: Each Shawnee 355 timer covers the overall span of

0.01 SEC to 999.9 MIN in two field-convertible ranges. The 355

indicating timer also offers two additional field-convertible ranges of

0.1-999.9 SEC or MIN

EASY TO SET AT ALL TIMES: The Shawnee timer is easily and ac-

curately 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

during a cycle.

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

size housing, the 355 occupies 40% less panel space than previ-

ous IC timers. Modern production and assembly techniques have

substantially reduced manufacturing costs and resulted in a 45%

cost saving.

OUTSTANDING REPEAT ACCURACY: Unsurpassed among industrial

timers regardless of cost, the Shawnee has a repeat accuracy of

±10 milliseconds on any setting within its overall range of 999.9

MIN, even in the face of wide swings in temperature or voltage and

regardless of the amount of reset time between cycles.

NOISE IMMUNITY: The 355 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

encountered in typical industrial environments
