Description Specifications Literature Description A compact version of the 335 timer, the ATC 355C is its exact functional duplicate, packaged in a 72 mm2 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 355C.Computer Tested Reliability: The solid-state 355C 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 355C's only significant mechanical component - has a life expectancy of 100,000,000 operations (no load). As a result, the 355C 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 355C timers 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 timer body is dust-tight from the front of panel.Wide Range: Each Shawnee 355C timer covers the overall span of 0.01 sec to 999.9 min in two field-convertible ranges. The 355C 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 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.Save 40% in Panel Space and Cost: Packaged in a 72mm2 DIN-size housing, the 355C 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.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 355C 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 encountered in typical industrial environments.Features: Computer Tested Reliability Cycle Progress Indication Plug-In and Dust Tight Wide Timing Range Easy to Set at All Times ±10 Milliseconds Repeat Accuracy State of California Proposition 65 WARNINGCancer and Reproductive Harm - www.P65Warnings.ca.gov.
