Product Description:
The H3DK-S1 is a DIN rail-mounted 4-mode multifunction timer from the Omron H3DK series, 22.5 mm slim width, with a single SPDT (1c) time-limit contact. Timing starts on power-up without an external start signal, making it a compact solution for the most common timing functions.
Operating modes:
- A: ON Delay
- B2: Flicker ON Start
- E: Interval
- J: One-shot Output
Key features:
- 4 commonly used timing modes in one unit
- SPDT (1c) time-limit relay output
- Power-ON start operation, no start signal required
- 8 timing ranges from 0.1 s to 1200 h
- Wide 24-240 VAC/DC supply (12 VDC version available)
- Green power LED and orange output LED
- 35 mm DIN rail mounting, 22.5 mm slim profile
Contact rating: 5 A @ 250 VAC resistive, 5 A @ 30 VDC resistive, 0.15 A max. @ 125 VDC resistive; minimum load 10 mA @ 5 VDC. Accuracy +/-1% FS max.; mechanical life 10,000,000 operations min.; electrical life 100,000 operations min. at 5 A @ 250 VAC. Operating temperature -20 to +55 C, IP30 (terminal block IP20).
Typical applications: compact ON-delay and interval timing, one-shot control, flicker indication, relay replacement in existing panels, lighting and heating delay, simple machine sequences and general industrial automation.

Applications:
Motor Control
This category includes methods such as star-delta (also known as wye-delta) reduced-voltage starting for motors. It is commonly used to reduce the initial surge current when starting large motors.
Additionally, it encompasses delayed start-up mechanisms for equipment like pumps, fans, compressors, and conveyors to ensure smooth operation and avoid mechanical stress.
Motor interlock systems and run-on timing features are also part of motor control, ensuring safe and efficient operation by coordinating the starting and stopping sequences.
Sequence & Process Control
Sequence and process control include ON-delay and OFF-delay switching functions that are integral in managing machine operation sequences effectively.
The use of interval pulses and one-shot output signals facilitates precise timing and control within automated procedures.
Signal-triggered ON/OFF delay loops allow for dynamic response based on input signals, while heating, lighting, and auxiliary circuit sequencing helps in orchestrating complex systems smoothly.
Signaling & Alarm
Applications in signaling and alarm systems include operating flashing warning lights and cycling signal towers to provide visual alerts.
Intermittent operation of buzzers and alarms is employed to draw attention without continuously sounding.
Outputs to indicators and sirens are often pulsed or intermittent, enhancing their effectiveness in alerting personnel.
Building, HVAC & Utilities
This area covers delay control for ventilation, air-conditioning, and lighting systems, optimizing energy use and comfort.
Valve and pump cycling is used in water treatment and irrigation systems to maintain consistent operation and conserve resources.
Timing controls are also essential for the operation of elevators, escalators, and auxiliary equipment within buildings.
OEM Machinery & Panels
Original Equipment Manufacturer (OEM) machinery often utilizes control panels for packaging, textile, printing, and machine-tool industries.
These systems are designed for general-purpose automation and can serve as relay replacements to improve performance and reliability.
Furthermore, retrofit and maintenance services support existing installations such as the H3DK and H3DKZ series, extending their operational lifespan.
