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

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

What supply options are supported for installation flexibility?


The unit accepts both 24V AC and 24V DC input supplies allowing use in AC or DC control systems.

How many separate circuits can be controlled independently?


Four changeover contacts are provided, permitting independent switching of up to four circuits.

What mounting and removal method aids field service?


A DIN-rail mount combined with plug-in Terminal connections allows quick replacement without rewiring.

What environmental temperature limits must be observed during operation?


The device is specified to operate within a range from -10 °C up to 50 °C for reliable performance.
