A compact version of the versatile 333 Timer, the ATC 353C 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 353C.

  • Control Versatility: The 353C 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 353C 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 353C'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 353C 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 353C 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 353C 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 353C 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 353C indicating timer provides cycle progress indication on a four-digit display located immediately above the digital setting number wheels. While the non-indicating Model 353C 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 353C 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 353C timers feature true plug-in design and are dust-tight from the front of panel.
