ATC 354C Counters
354C Series Shawnee II High Speed Counter

* 4 Digit Display
* Easy to Set
* Noise Immunity
* Plug-In & Dust-Tight
* Control Versatility
* High Repeat Accuracy

The solid-state 354 is manufactured 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 354’s only significant mechanical component-has a life expectancy of 100,000,000 operations (no load), while the optional solid-state switch module has a virtually unlimited life expectancy. As a result, the 354 achieves an overall reliability that surpasses even the high level achieved by previous Shawnee counters.
CYCLE PROGRESS INDICATION: The Shawnee 354 indicating counter provides cycle progress indication on a four-digit display located immediately above the digital setting number wheels. While the non-indicating Model 354B does not provide true cycle progress indication, its pilot light signals when the counter is running.

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 during a cycle.

NOISE IMMUNITY: The 354 does not have to be shielded: its transformer 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.

PLUG-IN AND DUST-TIGHT: All 354 counters feature true plug-in design and are dust-tight from the front of panel. 100% ACCURATE AND BOUNCE-PROOF: The repeat accuracy of the Shawnee 354 is 100% at all rated speeds, even in the presence of contact bounce. The 354 has two selectable levels of bounce suppression: a normal level which eliminates false counts at speeds up to 500 per second with reed switch inputs, and 5,000 per second with DC voltage pulses; and a high level, for speeds up to 80 per second with high-bounce contact closures (relays, precision switches, etc.).

HOUSING, IT OCCUPIES 40% LESS: Packaged in a 72mm2 DIN-size housing, the 354 occupies 40% less panel space than previous IC counters. Modern production and assembly techniques have substantially reduced manufacturing costs resulting in a 45% cost saving.

CONTROL VERSATILITY: The 354 operates either as a repeat cycle pulse generator or in single-cycle interval or delayed mode. You choose the kind of control action you want by installing jumpers on the terminal block. It also provides a choice of control output, a standard plug-in SPDT relay or an optional SPST solid-state switch module…plus an independent and separate DC output signal at Terminal 6.

ATC 356C Counters
356C Series Shawnee II Digital Counter

* Fast, Accurate and Bounce Proof
* Easy to Set
* Plug-In and Dust-Tight
* Cycle Progress Indication
* Computer Tested Reliability
* Noise Immunity

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.

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 during 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. While the non-indicating Model 356 does not provide true cycle progress indication, it can be wired so that the legend light is on during the cycle and the pilot light flashes with each pulse.

COMPUTER-TESTED RELIABILITY: The solid-state 356 is manufactured 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 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 transformer 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.

SAVE 40% IN PANEL SPACE AND COST: Packaged in a 72 mm2 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 expense especially for large users.

ATC 366C Counters
366C Series Long-Ranger Computing Counter

* Industry Standard Counter
* Contact Bounce and Noise Immunity
* Programmable Display
* Wide Range of Counts
* Compact, Plug-In and Dust Tight

Based on a powerful built-in microcomputer, the compact 366 is the most versatile and cost-effective counter ATC has ever built. No industrial counter has ever achieved a higher level of reliability and ruggedness than the 366. It has no moving parts in its electronic logic circuits, only plug-in circuit boards which are computer-tested for reliability and assembled virtually without hand wiring. Its few mechanical components have been selected for reliable service; long life relays with heavy-duty contacts and rotary set point selector switches with extremely low wear characteristics.
CONTACT BOUNCE AND NOISE IMMUNITY: No industrial counter offers greater immunity to noise and contact bounce than the 366. Most noise encountered in typical industrial environments is blocked by such design features as full-wave bridges and a transformer power supply… so effectively that the 366 does not have to be shielded. Furthermore the 366’s microcomputer employs redundant sampling logic to detect and reject any noise pulse that manages to penetrate its defenses. Through the same powerful technique, the microcomputer also detects and rejects even severe contact bounce. As a result, the 366 maintains absolute count accuracy and is virtually immune to false starts and reset, even in difficult industrial environments.

COMPUTATION: Through its internal microcomputer, the 366 keeps track of the set point throughout the count cycle. Whenever there is a change in set point, even during a cycle, it instantly recomputes the remaining count and accurately determines the number of counts before count-out. This unique capability is especially valuable in the count-down modes as it allows you to shorten or lengthen a cycle without loss of accuracy.

PROGRAMMABLE DISPLAY: The 366’s three-digit cycle progress display will count UP to or DOWN from the set point, depending on the position of an internal jumper. After count-out, the display will either STOP or GO. In the UP & GO program, the display counts up to the set point and continues to count after count-out; in the DOWN & GO mode, it counts down to the set point, then begins to count up (from zero) after count-out.

WIDE RANGE: Each 366 Long-Ranger covers the overall span of 1 to 99,900 counts in three switch-selected ranges of 1 to 999, 10 to 9990 or 100 to 99,900. It can be optimized within any selected range simply by removing appropriate selector knobs (e.g. with the counter in the 1 to 999 range, you can obtain a tamper-proof span of 1 to 99 by setting the left selector at 0 and removing the knob.) To the right of the three-digit display, a counting bar () blinks on each time a pulse is received. At left, a marker turns on when the delayed relay is energized at count-out.

SELF-DIAGNOSTICS: A built-in diagnostic program lets you verify-without using any test instrument-that the counter’s functional circuits are operating properly. Just follow the instructions on the flip-up card, using the counter’s own display for the test readout. If all self-test displays are correct, any malfunction is almost certainly due to external circuits or to the relays, not the counter.

COMPACT, PLUG-IN AND DUST-TIGHT: Packaged in a 72mm2 DIN housing, the 366 occupies 40% less panel space than most other industrial counters. It is a true plug-in counter that can be replaced in seconds without disturbing housing or wiring. The 366B is also fully gasketed and O ring sealed to be dust and water-tight whether panel or surface-mounted.

POSITIVE RESET TIME AND PULSE LENGTH: Digitally clocked by the microcomputer, the 366B’s reset time is consistently of the same duration, regardless of variations in line voltage, power supply or cycle length. When the 366B operates in repeat-cycle mode, the output pulse is also digitally clocked so that both the time of occurrence and its duration are consistent from cycle to cycle.
