ATC 0339A359Q2X Time Delay Relay

The ATC Diversified Electronics 0339A359Q2X Time Delay Relay is a socketable, DPDT (2 Form C) ON-delay timer designed for precise sequencing in industrial control circuits. It provides a fixed delay in the range of 0.3 seconds to 3 seconds and switches its Form C contacts after the interval, with a 10 A rating at 250 VAC or 30 VDC. The unit uses an octal plug-in base for quick replacement in panels and is part of ATC’s 339/359 time-delay relay family, which offers dial-selectable timing and repeatable operation across multiple supply configurations, including 120 VAC, 240 VAC, 24 VAC, 24 VDC, and 12 VDC options. Common applications include start/stop sequencing, interlock logic, delayed signaling, and other control-panel timing tasks where a compact, plug-in timer is advantageous.
