Product Description:
The H3DK-F is a DIN rail-mounted twin flicker timer from the Omron H3DK series, 22.5 mm slim width. Two separate dials set the ON time and OFF time, so the output can produce asymmetric flashing or cycling patterns. A front switch selects flicker OFF start or flicker ON start.
Key features:
- Twin flicker function: OFF start or ON start selectable
- Independent ON time and OFF time setting with dedicated dials and range switches
- 8 timing ranges from 0.1 s to 1200 h
- SPDT (1c) relay output, 5 A @ 250 VAC resistive load
- Wide 24-240 VAC/DC supply (12 VDC version available)
- Separate orange ON and green OFF output indicators
- 35 mm DIN rail mounting, 22.5 mm slim profile
Accuracy of operating time +/-1% FS max.; setting error +/-10% FS +/-0.05 s. Mechanical life 10,000,000 operations min.; electrical life 100,000 operations min. at 5 A @ 250 VAC. Operating temperature -20 to +55 C, protection IP30 (terminal block IP20).
Typical applications: flashing warning lights and signal towers, buzzer and alarm cycling, pulsed output, traffic and indicator flashing, intermittent pump or valve cycling, automation and panel indicator control.

Applications:
Motor Control
This category includes techniques such as star-delta (wye-delta) methods for starting motors with reduced voltage to minimize electrical stress. It also covers delayed start mechanisms for equipment like pumps, fans, compressors, and conveyors, ensuring smooth operation without sudden surges. Additionally, motor interlock systems and run-on timing features help in coordinating motor operations safely and efficiently.
Sequence & Process Control
Sequence and process control involve utilizing ON-delay and OFF-delay switches within machine sequences to manage timing effectively. Generating interval pulses and one-shot output signals is essential for precise operation control. Moreover, loops triggered by specific signals facilitate ON/OFF delays, which are crucial for managing heating, lighting, and auxiliary circuits systematically.
Signaling & Alarm
Signaling and alarm functionalities include the operation of flashing warning lights and cycling of signal towers to alert operators efficiently. Buzzers and alarms can be programmed for intermittent operation to avoid continuous noise. Pulsed or intermittent outputs are also designed for indicators and sirens, ensuring timely and effective attention to system statuses.
Building, HVAC & Utilities
Controls in building management, HVAC, and utility systems encompass ventilation, air conditioning, and lighting delay mechanisms to optimize energy consumption and comfort. Cycling valves and pumps in water treatment and irrigation systems ensure proper resource management. Additionally, timing solutions are applied to elevator, escalator, and auxiliary equipment to maintain smooth and safe operations.
OEM Machinery & Panels
This area focuses on control panels used in packaging, textile, printing, and machine-tool industries, offering customized control solutions. It supports general-purpose automation and serves as a replacement for traditional relay-based systems. Furthermore, it facilitates retrofitting and maintenance for existing installations such as H3DK and H3DKZ, enhancing the longevity and functionality of equipment.
