Product Description:
The H3DK-M2 is a DIN rail-mounted 8-mode multifunction timer from the Omron H3DK series, 22.5 mm slim width. A front mode switch selects eight operating modes, and a separate range switch covers eight timing scales. Relay R2 can be configured as either a time-limit contact or an instantaneous contact, giving flexible sequence design.
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

Applications:
Motor Control
This category includes applications such as star-delta (also known as wye-delta) reduced-voltage motor starting techniques. It is commonly used to reduce the initial inrush current during motor startup.
Other functions encompass the management of start-up delays for various equipment like pumps, fans, compressors, and conveyors, ensuring smooth and coordinated operation.
Additionally, motor interlock features and run-on timing are implemented to enhance safety and operational efficiency by controlling motor interactions and post-run cycles.
Sequence & Process Control
This area focuses on implementing ON-delay and OFF-delay switching within machine operation sequences to manage timing and order of events effectively.
It also involves generating interval pulses and one-shot output signals that are essential for precise control steps in automated processes.
Moreover, signal-triggered ON/OFF delay loops provide dynamic response capabilities based on input signals, facilitating adaptable control strategies.
Common applications include sequencing for heating elements, lighting systems, and auxiliary circuits to optimize overall machine performance.
Signaling & Alarm
In this domain, control of flashing warning lights and signal tower cycling is key to providing clear visual alerts to operators.
Buzzer and alarm systems are designed for intermittent operation to draw attention effectively without continuous noise pollution.
Additionally, pulsed or intermittent outputs to indicators and sirens are employed to ensure distinct and recognizable signaling in various environments.
Building, HVAC & Utilities
Control systems are applied to manage ventilation, air-conditioning, and lighting delays, enhancing energy efficiency and occupant comfort.
Valve and pump cycling plays a crucial role in water treatment and irrigation systems for maintaining optimal operation and resource management.
Furthermore, timing controls are vital for the operation of elevators, escalators, and auxiliary equipment within buildings, ensuring safety and reliability.
OEM Machinery & Panels
This category covers automation and control panels for various industries including packaging, textile, printing, and machine tools.
It also supports general-purpose automation tasks and serves as a relay replacement solution aimed at improving system performance.
Retrofitting and maintaining existing installations such as H3DK and H3DKZ ensures continued operation and integration with modern control devices.
Packing and Shipping:
Product Packaging and Shipping
The Variable Frequency Converter is carefully packaged to ensure safe delivery and optimal protection during transit. Each unit is securely enclosed in a custom-fitted foam insert within a sturdy, double-walled cardboard box to prevent movement and absorb shocks.
All accessories, manuals, and cables are packed separately within the box to avoid damage. The packaging materials are selected to be environmentally friendly and compliant with international shipping standards.
For shipping, we offer multiple options including standard ground shipping, expedited air freight, and courier services. Each shipment is tracked with a unique tracking number provided to the customer for real-time updates.
Before dispatch, every Variable Frequency Converter undergoes a final quality inspection and functional test to ensure it meets all specifications and performance criteria.
Special handling instructions are included on the packaging to alert carriers to handle the product with care. For bulk orders, pallets are used with shrink wrapping and corner protectors to secure multiple units together.
Our logistics team coordinates closely with shipping partners to ensure timely delivery and to manage any customs documentation required for international shipments.
