Allen-Bradley 355C351A30PX Digital Reset Timer

355C351A30PX is a Shawnee II digital reset timer designed for panel-mounted installation in industrial control panels. Part of ATC's Automatic Timing & Controls family, it provides a general-purpose reset timer function with a timing window of 0.01 to 99.99 seconds when powered from a 120 VAC supply. A dedicated reset input restarts the timing cycle, making it suitable for sequencing delays, interlocks, and machine-control tasks that require a repeatable timing interval. The unit's compact panel-mounted form factor supports integration alongside standard control circuits and relay logic. Typical applications include dwell delays between process steps, motor-start sequencing, and safety-interlock timing in automation systems that rely on timer devices for deterministic timing behavior. The 355C351A30PX is sold through multiple authorized distributors and is recognized in the Shawnee II product line as a digital timer with GP (general purpose) reset functionality. Key specifications confirmed by distributor listings include model 355C351A30PX, digital timing from 0.01 to 99.99 seconds, 120 V AC input, and panel-mounted installation. This timer enables precise, repeatable delays within control schemes without requiring programming, making it a straightforward component for a wide range of industrial automation tasks.
