Industrial 3-0305E004A10PX Timing Relay Module

Industrial 3-0305E004A10PX Timing Relay Module from Automatic Timing & Controls (ATC) is a plug-in ON-delay time relay in the Series 305 lineup, designed for rugged industrial control panels. When the 120 V AC, 60 Hz control supply is applied, it delivers a defined delay in the output of 0 to 15 seconds, with a re-set that occurs on power interruption to ensure a clean restart sequence. The unit uses a knob-set timing adjustment and a standard plug-in form factor, enabling quick substitution in compatible ATC/Marsh Bellofram timer relays without wiring changes. This model is currently discontinued by the manufacturer, and availability depends on distributor stock; buyers should verify compatibility and replacement options before purchase. Typical applications include sequencing of pumps, fans, conveyors, heating elements, and other industrial loads that require a precise start-up delay after power application or trigger events.
