Omron H3Y-4 Series Timer Relay, 0.5 to 10s Time Range, 24V AC Supply Voltage - H3Y-4 AC24 10S
This timer relay is a Compact timing device designed for control panels and DIN-rail installations, providing timed switching for industrial automation and electrical control systems. It operates from an AC24V supply and delivers multiple isolated switching outputs suitable for sequencing, delay and interlock functions in machinery and process control environments.
Features and Benefits:
• Four changeover contacts provide expanded switching capability
• 5A contact rating supports moderate load circuits
• 0.5–10 s adjustable timing covers short delay functions
• Plug-in terminals enable quick replacement and maintenance
• IP40 enclosure allows protected indoor panel mounting
• Accepts up to 250V AC switching for versatile circuits
• 5A contact rating supports moderate load circuits
• 0.5–10 s adjustable timing covers short delay functions
• Plug-in terminals enable quick replacement and maintenance
• IP40 enclosure allows protected indoor panel mounting
• Accepts up to 250V AC switching for versatile circuits
Applications
• Suitable for sequence control in conveyor systems
• Ideal for delay functions in motor starting panels
• Used for timing interlocks in machine safety circuits
• Can be used for signal timing in control cabinets
• Used with PLCs for auxiliary timed switching tasks

What contact arrangement does it offer and how does that help wiring?
It provides four changeover contacts, allowing independent switching of multiple circuits from a single timing element which simplifies wiring for complex control schemes.
What environmental temperatures can it tolerate during operation?
It is specified to operate between −10 °C and 50 °C, supporting typical indoor industrial environments without additional thermal conditioning.
How is the unit mounted and serviced within panels?
The product mounts on a DIN rail and uses plug-in Terminal connections, which facilitates Rapid removal and replacement during maintenance.
What approvals indicate suitability for industrial use?
It meets several standards including IEC and UL family standards and CCC, reflecting conformity with recognised electrical and safety requirements.
Can it accept DC control supplies as well as AC?
While the timing supply is AC24V, the relay design accepts a DC supply voltage up to 125V for other specified functions.
