Omron H3Y-4 Series Timer Relay, 1 to 30min Time Range, 24V AC Supply Voltage - H3Y-4 AC24 30M
This timer relay provides time-delay control for industrial automation and electrical systems, operating from an AC supply to manage switching sequences in control circuits. It is designed for DIN-rail mounting with a plug-in Terminal arrangement and supports multiple contact changes to control loads in sequence or timed intervals.
Features and Benefits:
• 4PDT contact arrangement enables four simultaneous switching paths, improving circuit flexibility
• Time range 1–30 min allows adjustable delays for process sequencing
• Contact rating 5A supports moderate current loads for control devices
• Switching voltage 30 VDC/250 VAC permits AC and DC load-switching versatility
• Supply options 24 VAC and 125 VDC accommodate varied control supplies
• Standards including UL, CE and CCC attest to recognised test conformity
• Time range 1–30 min allows adjustable delays for process sequencing
• Contact rating 5A supports moderate current loads for control devices
• Switching voltage 30 VDC/250 VAC permits AC and DC load-switching versatility
• Supply options 24 VAC and 125 VDC accommodate varied control supplies
• Standards including UL, CE and CCC attest to recognised test conformity
Applications
• Suitable for sequencing motor starters in manufacturing lines
• Ideal for staged lighting control in industrial facilities
• Used for timed valve actuation in fluid control systems
• Can be used for delayed relay interlocks in electrical panels
• Ideal for staged lighting control in industrial facilities
• Used for timed valve actuation in fluid control systems
• Can be used for delayed relay interlocks in electrical panels
What mounting method is required for installation?
It mounts on standard DIN rails and uses a plug-in Terminal Interface for quick insertion and removal.
Which environmental limits should I observe during operation?
Operate between -10°C and 50°C and ensure enclosure protection aligns with the IP40 rating.
How many independent switching functions can be achieved simultaneously?
Four separate changeover contacts are available, allowing multiple circuits to be switched at once.
