Product Description:
The H3DK-M1 is a DIN rail-mounted 8-mode multifunction timer from the Omron H3DK series, 22.5 mm slim width, fitted with one SPDT (1c) time-limit contact. It shares the eight timing modes and eight time ranges of the M2 version in a more compact 6-terminal configuration, with an external voltage start input (B1).
Operating modes:
- A: ON Delay
- B: Flicker OFF Start
- B2: Flicker ON Start
- C: Signal ON/OFF Delay
- D: Signal OFF Delay
- E: Interval
- G: Signal ON/OFF Delay
- J: One-shot Output
Key features:
- 8 selectable timing modes in one unit
- SPDT (1c) time-limit relay output
- Voltage start input (B1) for signal-triggered timing
- 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).

Applications:
Motor Control
This category involves starting motors with reduced voltage using the star-delta (wye-delta) method. It includes managing start-up delays for pumps, fans, compressors, and conveyors to ensure smooth operation. Additionally, motor interlock mechanisms and run-on timing are implemented to enhance safety and efficiency.
Sequence & Process Control
Sequence and process control covers ON-delay and OFF-delay switching within machine sequences, ensuring precise timing for operations. It also incorporates interval pulses and one-shot output signals to trigger specific actions. Signal-triggered ON/OFF delay loops are utilized, along with sequencing for heating, lighting, and auxiliary circuits to maintain optimal process flow.
Signaling & Alarm
This area focuses on the management of warning lights and signal towers, including flashing and cycling patterns. It also includes intermittent operation for buzzers and alarms to capture attention effectively. Pulsed or intermittent outputs are supplied to various indicators and sirens to enhance safety and communication on-site.
Building, HVAC & Utilities
In the context of building services, ventilation, air-conditioning, and lighting are controlled with delay functions to improve comfort and energy efficiency. Valve and pump cycling is performed in water treatment and irrigation systems to maintain proper operation. Timing control is also critical for elevators, escalators, and auxiliary equipment to ensure safety and reliability.
OEM Machinery & Panels
OEM machinery applications include control panels for packaging, textile, printing, and machine tools. These systems serve as general-purpose automation solutions and can replace traditional relays. They are also suitable for retrofitting and maintaining existing H3DK and H3DKZ installations, extending the life and functionality of the equipment.
Packing and Shipping:
Product Packaging and Shipping
The Variable Frequency Converter is carefully packaged to ensure it arrives in perfect condition. Each unit is securely placed in an anti-static bag to protect against electrostatic discharge, then cushioned with foam padding inside a robust, corrugated cardboard box. The packaging is designed to withstand handling and transportation stresses, minimizing the risk of damage.
For shipping, the product is labeled with all necessary handling instructions, including “Fragile” and “This Side Up” to ensure proper care during transit. Depending on the destination, the Variable Frequency Converter can be shipped via air, sea, or land freight, with tracking information provided to the customer for real-time shipment monitoring.
We recommend inspecting the package upon arrival for any visible damage and reporting any issues immediately to ensure prompt resolution. Our packaging and shipping procedures comply with international standards to guarantee safe and reliable delivery worldwide.
