Omron H3YN-4 Time Delay Relay is designed to operate from a 100–120 VAC supply with 50/60 Hz mains and provides four selectable timing ranges: 1 second, 10 seconds, 1 minute, and 10 minutes. In automation and control circuits, it functions as a timing element to create deliberate delays for activation or deactivation of loads or relays, enabling simple sequencing and interlock behavior. This compact device is suitable for industrial environments where a reliable delay is required on 100–120 VAC systems, consolidating timing control in a single relay.
