Omron Corporation H3Y-2 Miniature On Delay Timer Relay

The Omron H3Y-2 is a compact miniature on-delay timer relay that provides a fixed 30-second delay in control circuits, enabling precise sequencing without the need for external timing modules. This model operates from 100–120 VAC and is designed to be mounted in control panels, delivering reliable timing while occupying minimal space in automation layouts. As part of Omron's H3Y-2 family, it energizes a load after the input is applied, making it suitable for sequencing and interlock applications, or timed activation of devices such as pumps, conveyors, and indicator lights. Key specifications include 30-second on-delay timing and 100–120 VAC compatibility, making it a straightforward choice for applications requiring a simple, fixed-delay timing solution in standard AC control circuits.
