Omron H3Y-4 Series Timer Relay, 0.1 to 3min Time Range, 24V AC Supply Voltage - H3Y-4 AC24 3M
This timer relay provides time-delayed switching for automation and control panels, functioning as an ON‑delay device compatible with a 24V AC supply. It is designed for DIN-rail mounting and connects via a plug‑in Terminal arrangement to simplify installation in electrical and mechanical systems. The unit operates across a short time interval suited to sequencing and delay tasks in industrial environments.
Features and Benefits:
• Four changeover contacts deliver simultaneous circuit control
• Adjustable delay range from 0.1 to 3 min enables precise timing
• Rated contact current of 5A supports medium‑load switching
• Switching capability up to 250V AC and 30V DC handles diverse circuits
• Plug‑in Terminal design reduces downtime during replacement
• Adjustable delay range from 0.1 to 3 min enables precise timing
• Rated contact current of 5A supports medium‑load switching
• Switching capability up to 250V AC and 30V DC handles diverse circuits
• Plug‑in Terminal design reduces downtime during replacement
Applications
• Suitable for sequence control in conveyor and material‑handling systems
• Ideal for timed activation of motors and solenoids in production lines
• Used for delayed start of auxiliary equipment in control panels
• Can be used for interlock timing in safety and process‑control systems
