Omron H3Y-4 Series Timer Relay, 24V AC Supply Voltage, 2 to 60s Time Range - H3Y-4 AC24 60S

This timer relay provides adjustable time-delay control for industrial automation and control panels, designed to switch circuits after a set interval within a 2 to 60 s range. It operates from a 24V AC supply and mounts on standard DIN-rail systems, offering multi-contact switching for sequential or delayed operations in electrical and mechanical installations.

Features and Benefits:

• Four changeover contacts enabling multi-circuit sequencing
• 5A contact rating supporting moderate load switching
• Plug-in terminals for Rapid installation and serviceability
• 250V AC switching capability for common control voltages
• Temperature tolerance from −10 °C to 50 °C for varied site conditions

Applications

• Suitable for staging motor start sequences in plant control panels
• Ideal for delay functions in conveyor and material-handling systems
• Used for timed control in HVAC and building-management circuits
• Can be used for interlock delays in safety and machinery systems

What mounting method does it use for panel integration?

It clips to a DIN rail to allow secure rail-mounted installation and easy replacement without panel rewiring.

How many independent switching points are available?

There are four changeover (4PDT) contacts permitting simultaneous control of multiple outputs.

Which approvals ensure it meets recognised manufacturing standards?

It conforms to a range of international standards including UL 508, IEC 60664-1, EN 61812-1, CCC and relevant certification bodies.

What Terminal style facilitates maintenance and wiring changes?

The plug-in Terminal arrangement allows Rapid withdrawal and reconnection for servicing or module swaps.

What environmental protection and operating limits apply?

The unit carries an IP40 enclosure rating and is specified for operation between −10 °C and 50 °C.
