Omron H3Y-4 Series Timer Relay, 0.1 to 3min Time Range, 24V AC Supply Voltage - H3Y-4 AC24 3M

This timer relay provides time-delayed switching for automation and control panels, functioning as an ON‑delay device compatible with a 24V AC supply. It is designed for DIN-rail mounting and connects via a plug‑in Terminal arrangement to simplify installation in electrical and mechanical systems. The unit operates across a short time interval suited to sequencing and delay tasks in industrial environments.

Features and Benefits:

• Four changeover contacts deliver simultaneous circuit control
• Adjustable delay range from 0.1 to 3 min enables precise timing
• Rated contact current of 5A supports medium‑load switching
• Switching capability up to 250V AC and 30V DC handles diverse circuits
• Plug‑in Terminal design reduces downtime during replacement

Applications

• Suitable for sequence control in conveyor and material‑handling systems
• Ideal for timed activation of motors and solenoids in production lines
• Used for delayed start of auxiliary equipment in control panels
• Can be used for interlock timing in safety and process‑control systems

What environmental limits must I observe during operation?

The relay is intended for use between −10 °C and 50 °C and is not sealed for outdoor exposure, having an IP40 rating.

How is the unit secured within an electrical panel?

It mounts onto a standard DIN rail and plugs into mating sockets via its plug‑in terminals for Rapid installation and replacement.

What standards and approvals relate to its use in industrial settings?

It conforms to relevant industrial electrical standards including EN 61812‑1 and IEC 60664‑1 and holds approvals from recognised certification bodies.

What electrical supply flexibility does it offer?

The device is specified for a 24V AC supply and also accommodates a 125V DC supply rating for its Coil circuitry.
