353C Series Shawnee II Digital Programmable Timer

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.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.
