Omron H3DK Series Timer Relay, 240V Supply Voltage, 0.1to12s Time Range - H3DK-HDS AC200-240V

This timer relay provides time-delayed switching for control and automation systems, operating on an AC supply to delay contact opening after power is removed. It is intended for DIN rail mounting within control panels and delivers a single changeover contact suitable for routine industrial timing tasks.

Features and Benefits:

• SPDT contact arrangement for single-circuit switching with flexibility
• 5A contact rating enabling moderate load control in automation systems
• Power-off delay function to maintain output for a defined interval
• Time setting from 0.1 to 12 s for precise short-duration timing
• Screw Terminal connections for secure wiring and easy replacement
• RoHS conformity and specified IP20/IP30 protection for panel installations

Applications

• Suitable for sequencing motor shutdowns in conveyor controls
• Ideal for delay timing in machine safety interlocks
• Used for lamp or indicator hold-off after power loss
• Can be used for timed valve shut-off in pneumatic systems

What supply voltage does it require for operation?

It accepts an AC supply rated for 240V AC and is designed to operate at that nominal mains level.

What mounting method is provided for panel installation?

It is configured for attachment to a standard DIN rail for straightforward integration into control enclosures.

What temperature range can it operate within?

The device is specified to function between -20 °C and 55 °C ambient, suitable for typical industrial environments.

How is the product physically secured to wiring?

Electrical connections are MADE via screw terminals to ensure firm conductor retention under vibration.

What form factor should be expected for panel space planning?

The unit uses a Compact housing with a width of 22.5mm for dense mounting arrangements.
