A compact version of the versatile 333 Timer, the ATC 353B 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 353B.
CONTROL VERSATILITY: The 353B 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. Choose a standard plug-in SPDT relay or optional SPST solid-state switch module plus an independent-24VDC output signal at Terminal 16.

COMPUTER TESTED RELIABILITY: The solid-state 353B 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 353B’s only significant mechanical component - has a life expectancy of 100,000,000 operations (no load), while the optional solid-state switch module has virtually unlimited life expectancy. As a result, the 353B achieves an overall reliability that surpasses even the high level achieved by previous Shawnee timers.

SAVE 40% IN PANEL SPACE AND COST: Packaged in a 72mm2 DIN-size housing, the 353B occupies 40% less panel space than previous IC timers. Modern production and assembly techniques have substantially reduced manufacturing costs and resulted in a 45% cost saving.
WIDE RANGE: Each Shawnee II 353B timer covers the overall span of 0.01 sec to 999.9 min in four field-convertible ranges.

EASY TO SET: The Shawnee timer 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 353B 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.

CYCLE PROGRESS INDICATION: The Shawnee 353B indicating timer provides cycle progress indication on a four-digit display located immediately above the digital setting number wheels. While the non-indicating Model 353B does not provide true cycle progress indication, it has a pilot light which is on during the timing cycle and a legend light which is on when there is power to the timer.

OUTSTANDING REPEAT ACCURACY: Unsurpassed among industrial timers regardless of cost, the Shawnee 353B 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.

PLUG-IN AND DUST-TIGHT:
All 353B timers feature true plug-in design and are dust-tight from the front of panel.

ATC 365C Digital Timers
365C Long-Ranger Computing Timer

* Industry standard digital timer
* Adjustable range 0.01 sec. to 999 hours
* High brightness VF display
* High noise immunity
* UL recognized

The ATC 365C Timer is microprocessor-based digital timer with three rotary knobs for setting and adjustment of the Preset. The Preset can be any three-digit value from .01 Sec to 999 Hrs. The Decimal and Range are switch selectable. The high-intensity blue vacuum fluorescent display is DIP switch selectable to Timeup or Timedown. Two heavy-duty 7A DPDT relays provide instantaneous, interval or delayed output control. Plug-in panel mounting allows easy replacement without the removal of field wiring.

COMPUTATION: Through its internal microcomputer, the 365C keeps track of the set point throughout the time cycle. Whenever there is a change in set point, even during a cycle, it instantly re-computes the time remaining and accurately determines time-out. This unique capability is especially valuable in the time-down modes as it allows you to shorten a cycle without loss of accuracy.

POSITIVE RESET TIME AND PULSE LENGTH: Digitally clocked by the microcomputer, the 365C’s reset time is consistently of the same duration, regardless of variations in line voltage, power supply or time cycle. As a result, the 365C is not subject to false reset from momentary power interruptions (less than 30 ms). When the 365C operates in repeat-cycle mode, the output pulse is also digitally clocked so that both its occurrence and duration are consistent.

WIDE RANGE: Each 365C Long-Ranger covers the overall span of 0.01 sec. to 999 hrs., in nine switch-selected ranges of 0 to 9.99,99.9 or 999 sec., min. or hrs. The timer can be optimized within any selected range simply by removing appropriate selector knobs (e.g. with the timer in the 9.99 sec. range, you can obtain a tamper-proof span of 0.99 by setting the left selector at 0 and removing the knob).

PROGRAMMABLE DISPLAY: Depending on the position of an internal jumper, the 365C’s three-digit cycle progress display will time UP to or DOWN from the set point; after time-out, it will either STOP or GO (i.e. display the time elapsed after time-out). To the right of the three-digit display, a timing bar “-” blinks once per second during the timing cycle and rapidly after time-out. At left, a marker “∇” turns on when the delayed relay is energized. The 365C is also available without display but with a pilot light that blinks once per second during the cycle and rapidly after time-out.

NOISE IMMUNITY: The 365C has formidable defenses against noise: transformer power supply, full-wave bridges, buffered logic. Furthermore its microcomputer detects; and rejects; noise pulses that manage to penetrate its defenses. No industrial timer has ever offered greater noise immunity.

RELIABILITY AND RUGGEDNESS: ATC firmly believes that no industrial timer has ever achieved a higher level of reliability and ruggedness. The 365C’s electronic components have no moving parts and are assembled, virtually without hand wiring, from computer-tested circuit boards. Its few mechanical components have been selected for reliable service; the two load relays have a life expectancy of 100,000,000 operations and heavy-duty contacts rated at 7 amps; and the three rotary set point selector switches exhibit extremely low wear.

COMPACT, PLUG-IN AND DUST-TIGHT: Packaged in a 72mm2 DIN housing, the 365C occupies 40% less panel space than conventional timers. It is a true plug-in timer that can be replaced in seconds without disturbing housing or wiring. The 365C is also fully gasketed and O-ring sealed to be dust and water-tight.

SELF DIAGNOSTICS: The time will display “FAIL” anytime there is a problem or the knobs are in between digits.

WIDE RANGE: Each 365M timer covers the overall span of 0.01 Sec. to 999 Hrs., in nine switch-selectable ranges of 9.99, 99.9, or 999 Sec, Min, or Hrs.

EASY-TO-ADJUST PRESET: ATC’s unique three rotary switches for easy setting and adjustment of the preset time is an industry standard. The switches can be adjusted anytime, even during a timing cycle. The timer is constantly scanning the preset setting and instantly
re-computes the time cycle if a preset change is detected. This is especially valuable in the Timedown mode allowing you to shorten or abort the current time cycle without the removal of power.

SELF-CALIBRATING: The microprocessor automatically calibrates the timer for 50 or 60Hz power operation, there are no switches or jumpers to set.

PROGRAMMABLE DISPLAY: An internal DIP switch can be set for Timeup or Timedown and Stop display operation on the Arrangement 30 model. The Arrangement 50 model can be set for Timeup or Timedown and go. There is a horizontal timing bar “
-” which appears to the right of the display and blinks once per second during timing and rapidly at time-out. At left, a timed-out symbol “∇” blinks after time-out indicating when the magnetic delayed relay is latched.

MAGNETIC LATCH RELAY: The 365M utilizes a unique magnetic latch delayed relay which energizes, latches, at time-out. Once latched it will not unlatch even with power removed or the unit is unplugged from the housing. It will only unlatch when power is momentarily applied to the Reset, terminal 16.

NON-VOLATILE MEMORY: An EEPROM memory chip to retain the time value during a loss of power and continues timing when power is restored. No battery is required.
