Datasheet

Omron H3DK Series Timer Relay, 200/240V AC Supply Voltage, 1 to 12 and 10 to 120s Time Range - H3DK-HDL AC200-240V

This timer relay provides adjustable delay control for automation and electrical systems, designed to be mounted on a DIN rail and integrated into control panels. It operates from industry AC supplies and can also accept a wide DC supply range, offering a single switching contact for timed control of loads up to standard switching voltages. Its construction meets common international electrical safety and performance standards for use in industrial environments.

Features and Benefits:

• 200/240V AC supply compatibility for straightforward mains connection
• 12–240V DC supply option allowing flexible DC interfacing
• Single contact rated for 5A supporting moderate load switching
• Time ranges selectable between 1–12s and 10–120s for flexible timing
• Screw terminals enable secure, vibration-resistant wiring
• IP30 enclosure protection suitable for enclosed panel installations

Applications

• Suitable for sequential control in assembly-line automation
• Ideal for timing functions in motor starter circuits
• Used with PLC interfaces for external time-delay tasks
• Can be used for interval control of industrial signalling circuits

What ambient temperatures can it withstand during operation?

It is specified to operate between −20°C and 55°C allowing use across typical plant environments.

How is the device physically secured in control cabinets?

It is designed for DIN rail mounting which enables Rapid installation and removal on standard rails.

What approvals indicate suitability for international installations?

It carries multiple recognised approvals including EN and North American safety listings to meet various regulatory requirements.

How does the relay handle insulation and clearance requirements?

The product conforms to relevant IEC insulation standards to ensure adequate electrical separation in rated conditions.
