Product Information
Full details
The Omron Timer Relay H3DK-F (H3DK6006R) is designed for industrial automation professionals needing precise control over timing sequences. Its key benefit lies in its dual pulse/pause functionality with independent time settings, allowing for complex cycle control. A potential caveat is its specific application within industrial settings, requiring basic electrical knowledge for installation.

FAQs
What is the maximum load this timer relay can switch?
The H3DK-F features an SPDT contact rated for a maximum of 5A at 250VAC or 30VDC. For loads exceeding this, an external contactor or relay is necessary.
Can this timer be used with both AC and DC power supplies?
Yes, the H3DK-F is designed to operate with a wide voltage range of 24-240 VAC/DC.
What does 'Dual Pulse/Pause Timing' mean?
It means the timer can independently control two distinct time periods: a 'pulse' duration (when the output is active) and a 'pause' duration (when the output is inactive). This allows for complex on/off cycling.
How do I set the time range?
The time range is typically set using rotary switches or dials on the front of the unit. Refer to the specific markings for the desired time units (seconds, minutes, hours) and range.
What are the 'Flicker OFF Start' and 'Flicker ON Start' modes?
These are operating modes. 'Flicker OFF Start' typically means the timing cycle begins with the first OFF time. 'Flicker ON Start' typically means the timing cycle begins with the first ON time.
Is this timer suitable for high-precision timing applications?
The H3DK-F offers precise timing within its specified ranges for industrial automation. For extremely high-precision laboratory or measurement applications, specialized timers might be more appropriate.
What is the physical size and mounting method?
It has a compact 22.5mm width and is designed for mounting on a standard 35mm DIN rail.
Troubleshooting
Timer not powering on
Verify that the correct voltage (24-240 VAC/DC) is applied to the power terminals and that the power source is active. Check all wiring connections for proper security.
Relay does not switch contacts
Ensure the timer has reached its set time limit. Confirm the correct mode (e.g., Flicker ON/OFF Start) is selected and that the input signal (if applicable) is correctly wired and functioning. Check if the load is within the 5A rating.
Inconsistent timing or inaccurate delays
Double-check that both time range dials are set accurately. Ensure the operating voltage is within the specified range and stable. Avoid environmental factors like extreme temperatures or voltage fluctuations that could affect performance.
Timer cycles incorrectly
Review the selected operating mode (Flicker OFF Start, Flicker ON Start) and ensure it matches the intended application. Verify the settings for both independent time ranges (pulse and pause) are correct.
Pros and Cons
Pros
- Versatile dual timing functions for complex sequences
- Wide voltage compatibility simplifies integration
- Space-saving design ideal for crowded control panels
- Reliable performance for industrial automation
- Extensive time range adaptability
Cons
- Requires basic electrical wiring knowledge for installation
- SPDT contact rating may be insufficient for high-power loads
- Specific industrial application focus may limit consumer use
- Dual settings might require careful configuration
Setup, Compatibility & Care
Setup:
- Mounting: Securely mount the timer relay onto a standard 35mm DIN rail within a control panel.
- Wiring: Connect the power supply (24-240 VAC/DC) to the designated power terminals. Wire the control input and output load according to your circuit diagram and the SPDT contact configuration (Common, Normally Open, Normally Closed).
- Setting Adjustment: Use the rotary switches or dials to set the desired time ranges for both the pulse and pause functions, and select the operating mode (e.g., Flicker OFF Start, Flicker ON Start).
Compatibility:
- Voltage: Compatible with a wide range of AC and DC voltages from 24V to 240V.
- Load: The 5A SPDT contact is suitable for switching AC loads up to 5A at 250VAC or DC loads up to 5A at 30VDC. For higher loads, an external relay or contactor is required.
- Environment: Designed for industrial environments; ensure protection from excessive moisture, dust, and extreme temperatures.
Care:
- Cleaning: Periodically dust the unit with a dry cloth. Avoid using solvents or wet cloths, as this may damage the components.
- Inspection: Regularly check wiring connections for tightness and signs of wear.
