Omron H3Y-4 Series Timer Relay, 0.1 to 3min Time Range, 24V Supply Voltage - H3Y-4 DC24 3M
This timer relay provides adjustable time-delay control for industrial automation and control panels, functioning as a plug-in timing device that fits DIN-rail installations. It is designed for 24V supply systems and multi-contact switching tasks, delivering time delays in the short-range minutes typically required for sequencing, interlocks and process timing in electrical and mechanical set-ups.
Features and Benefits:
• 4PDT contact arrangement enabling simultaneous multi-circuit switching
• Time range adjustable from 0.1 to 3 min for precise short delays
• Rated contact current 5A to drive auxiliary loads directly
• Switching capability up to 250V AC and 30V DC for mixed circuits
• Plug-in terminals for Rapid replacement and maintenance
• IP40 enclosure suitable for protected control-panel environments
• Time range adjustable from 0.1 to 3 min for precise short delays
• Rated contact current 5A to drive auxiliary loads directly
• Switching capability up to 250V AC and 30V DC for mixed circuits
• Plug-in terminals for Rapid replacement and maintenance
• IP40 enclosure suitable for protected control-panel environments
Applications
• Suitable for sequencing auxiliary circuits in production lines
• Ideal for interlock timing in motor control cabinets
• Used with PLCs as a simple timing adjunct or replacement device
• Can be used for delayed start of pneumatic and hydraulic valves
• Suitable for time-controlled signalling and alarm suppression
