Omron H3Y-4 Series Timer Relay, 1 to 30s Time Range, 24V AC Supply Voltage - H3Y-4 AC24 30S
This timer relay provides timed control for industrial automation and electrical systems, delivering an adjustable delay function for on‑delay applications. It is designed for DIN‑rail mounting and accommodates multiple switching circuits, operating from an AC supply to sequence processes or protect equipment within control panels.
Features and Benefits:
• Four changeover contacts offering simultaneous multi‑circuit control
• Adjustable delay spanning 1–30 s for precise timing control
• Rated switching current of 5A for moderate load switching
• Plug‑in terminals for quick replacement and reduced downtime
• Accepts 24V AC supply enabling low‑voltage control integration
• Withstands switching voltages up to 250V AC for broad compatibility
• Adjustable delay spanning 1–30 s for precise timing control
• Rated switching current of 5A for moderate load switching
• Plug‑in terminals for quick replacement and reduced downtime
• Accepts 24V AC supply enabling low‑voltage control integration
• Withstands switching voltages up to 250V AC for broad compatibility
Applications
• Suitable for sequencing motors and contactors in control panels
• Ideal for timed lighting or signalling circuits on industrial sites
• Used for interlocking routines across multiple control lines
• Can be used for delay functions in conveyor and process equipment

What Terminal arrangement allows independent circuit control?
The device uses four changeover contacts, enabling separate normally open and normally closed circuits for each channel.
What mounting method facilitates panel retrofits?
It is configured for DIN‑rail mounting to simplify installation within standard control enclosures.
What environmental limits govern its use?
The unit operates between -10°C and 50°C and has an enclosure protection rating corresponding to IP40.
Are there recognised standards for its safety and compatibility?
It conforms to multiple international standards including UL508, IEC 60664‑1 and EN 61812‑1 among others.
How Compact is the device for dense panel layouts?
The module occupies a slim profile with a width of 21.5mm to conserve rail space.
