ATC 339A359Q2X Time Delay Relay

ATC 339A359Q2X Time Delay Relay from Automatic Timing & Controls is a plug‑in timing relay that adds a controlled delay to electrical circuits in control panels and automation systems. It uses a dial to select timing settings and supports on‑delay and interval timing modes, enabling the output to switch after a programmed pause or to operate in timed cycles. The unit is designed for plug‑in installation on a compatible ATC socket base, promoting fast replacement and straightforward field adjustment in equipment such as motors, pumps, fans, interlock circuits, and sequencing loads in industrial or commercial applications. Built as part of the ATC 339 family, it provides repeatable timing performance across typical industrial environments and is intended for use in applications where predictable delay before switching is required.
